Optical vision aid with additional astigmatism Description The invention relates to the use of an optical vision aid with at least one spectacle lens by an observer for viewing an object, wherein the visual aid for at least one viewing direction has a matched to an eye of the observer dioptric action, which is composed of several dioptric components of action. Moreover, the invention also relates to a method and a system for determining a parameterization of an optical visual aid for an eye of an observer who has a dioptric effect tuned to the eye of the observer. In particular, this invention relates to a pair of spectacles having a spectacle lens which can be positioned in front of the eye of an observer. However, an optical vision aid in the sense of the invention is also an arrangement of optical elements which can be positioned in front of the eye of an observer and which has at least one spectacle lens or several spectacle lenses with different optical properties. By a dioptric action component of the dioptric power of the visual aid, this invention means a contribution of the visual aid for compensating for the visual deficiency of the observer in the form of at least spherical effect (sphere) and astigmatic effect (cylinder and associated axial position). The spherical power (spherical power) of an optical element is given below in unit [D] = [1 / m] (diopter), the astigmatic effect (cylindrical power) of an optical element in unit [DC] = [1 / m ] and the axis position in degrees. For the purposes of the invention, a best possible corrective effect of a dioptric component of the dioptric action of the visual aid is understood to mean the property of the dioptric component of effect that the contribution of the dioptric component to the dioptric function of the visual aid as a whole is at least up to 1/5 of the observer's habitual refractive error D, preferably up to 1/8 D of the spherical effect, at least to 1/5 DC, preferably up to 1/8 DC of the astigmatic effect and ± 5 ° Achslage compensates. The habitual refractive deficit can z. B. be determined by a refraction. In general, the optician or ophthalmologist creates a prescription (prescription) with prescription values for the best possible corrective effect of the o.a. dioptric effect component of the visual aid. Under the partially corrective effect of a dioptric component of the dioptric action of the visual aid, this invention understands the property of this dioptric component of effect that the contribution of the dioptric component to the dioptric function of the visual aid as a whole at least partially corrects the so-called habitual refractive deficit of the observer. However, in the context of the invention, a dioptric component of effect is only partially correct if, due to the only partially corrective effect, the visual acuity of the observer is reduced by no more than 0.2 logMAR from the visual acuity achieved with a dioptric component of action which is the best possible corrective Has effect in the context of the invention. The invention combines one or more dioptric activity components for best possible corrective action and one or more dioptric activity components for a partial corrective effect. The partially corrective effect can be achieved by combining different optical elements in a visual aid or by a single optical element, for. B. a spectacle lens with a dioptric power Reali Siert, which is composed of dioptric components with a spherical effect and / or an astigmatic effect and / or a prismatic effect. In order for an observer to be able to see sharply an object located in a certain distance range, a sharp image of the object on the retina of the eyes of the observer is required. The prerequisite for this is that the image produced on the retina is either located exactly in an image plane conjugate to the object plane, or that the depth of field of the image of the object is so great that the blur associated with an image on the retina of the image plane conjugate to the object plane can not be perceived by the observer. The vision of the human eye is also called visual acuity V. The visual acuity of the human eye is defined as the angle of vision, measured in angular minutes, below which an observer can just detect an object with an eye at an opening angle α of the observation beam: V: = α / 1 ' Thus, the eye of an observer with visual acuity 1 can barely resolve a 1.5 mm object at a distance of 5 m. For checking the visual acuity are called Sehprüfgeräte use such. For example, the vision tester i.Polatest® or the vision tester Vi-suscreen 500 from Zeiss. With this visual inspection device, the eyes of an observer can be visualized by projecting on a display surface different Sehzeichen in the form of a Landolt ring or as a Snellen E-hook or as numbers or letters formed characters in different sizes. In EP 1 880 663 A1 is a Visual inspection device with a display for the display of optotypes described. The different sizes of the optotypes displayed in the visual inspection devices of an observer correspond to different values of the visual acuity. In order to check the visual acuity, the optotypes displayed to an observer are reduced until the observer can no longer clearly recognize the optotypes, but can only guess. The healthy human eye has the ability to ensure a sharp image on the retina by altering the shape of the natural eye lens for objects that are in different ranges of distance. This ability is called the accommodation capacity. With age, the human eye loses the ability to clearly recognize small objects in a short distance of the subject. This is because the accommodation capacity of the human eye decreases with advancing age and therefore becomes misleading for nearby objects (presbyopia). Defective vision of the human eye can often be completely or at least partially corrected by means of optical vision aids. An optical vision aid of the aforementioned type is known from EP 0 857 993 A2. There, a lens designed as a progressive lens is described which has a tuned to the eye of an observer dioptric effect. This dioptric effect of the spectacle lens is composed here of several dioptric components of action that belong to different visual zones of the progressive lens. In this way, an observer will be able to see clearly in different distance ranges even with limited accommodative power. The object of the invention is to allow an observer to observe objects with increased depth of field and to provide a method and a system for determining a parameterization of an optical visual aid with which an observer with an increased depth of field can observe objects. This object is solved by the use of an optical vision aid given in claim 1, the method specified in claim 7, the computer program indicated in fig. 12 and the system for determining a sought parameterization of an optical visual aid indicated in claims 13 and 14. Advantageous developments of the invention are specified in the dependent claims. The spectacle lens of an optical vision aid used according to the invention can, for. B. as a multifocal gl as, in particular be designed as a progressive lens. The spectacle lens of an optical vision aid used according to the invention can also have a prescription surface. This recipe surface can z. B. be a spectacle lens back surface. A vision aid used in accordance with the invention has, for at least one viewing direction, a dioptric effect which is matched to an eye of the observer and which is composed of a plurality of dioptric components of action. In this case, a first dioptric component of action of the plurality of dioptric components of action for the eye of the observer in a defined distance range has an optimally correcting effect for the viewing direction. Another dioptric action component of the multiple dioptric activity components for the eye of the observer in the defined distance range has an additional astigmatic, partially correcting effect for the viewing direction. In other words, the vision aid provided for the spectacle wearer does not have exactly the recipe values for the spherical effect, the antigmatical effect and its axial position and, if necessary, for the prismatic effect and its basis, which are determined by a refraction determination, for a line of sight provide the best possible corrective effect, but it has an additional astigmatic effect with possibly over the axis position according to the prescription deviating or coincident axis position for a partial corrective effect. Namely, the inventors have recognized that the natural depth of field of the human eye can be increased with an optical vision aid having an additional astigmatic effect. With an optical visual aid used according to the invention, an astigmatism is thus induced for the eye of the observer. In this case, the use of a visual aid is to be understood as meaning, in particular, that the visual aid is selected from a stock in virtual or figurative form, which provides the dioptric effect specified above for the observer. Alternatively, of course, a visual aid can be individually calculated and manufactured for the observer. One can still speak here of a prescription production, wherein the production based data - as described above - are not exactly the determined from a refraction measurement recipe values, but these are the above-described additional astigmatic effect with associated axis position for a partial corrective effect modified. In this regard, the inventors have found, in particular, that when the first action component has a far-correcting eye-effect optimizer effect and the second action component other than the first action component has an additional negative astigmatism for the observer's eye, the natural depth of field of the human eye can be optimized. In particular, the inventors have found that if the first component of action has an eye direction optimizing eye correction effect for a distance As ^ 4m of an object from the corneal vertex of the eye, then the additional dioptric power component has an additional negative astigmatism for the eye Eye of the observer for the viewing direction, a particularly good visual impression can be achieved by the additional negative astigmatic effect is a cylinder power BK, wherein for the cylinder power BK is -1,0 DC < BK < -0.125 DC, se -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC, and wherein the additional negative astigmatic effect has an axis position φ of 70 ° < φ < 110 °, preferably 80 ° < φ < 100 °, particularly preferably φ * 90 °, or an axis position φ given in the TABO scheme with an axis position φ given in the TABO scheme with -20 ° < φ < 20 °, preferably -10 ° < φ < 10 °, more preferably φ «0 ° has. A particularly good visual impression can also be achieved by the fact that the first dioptric component of effect has the eye direction of the observer for a distance As ^ 1 m of an object from the corneal vertex of the eye optimally correcting effect for the line of sight and the further dioptric component of effect an additional negative astigmatic For the eye of the observer, the additional negative astigmatic effect having a cylinder power BK of -1.0 DC < BK < -0.125 DC, se -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and an axis position φ given in the TABO scheme with 70 ° < φ < 110 °, preferably 80 ° < φ < 100 °, more preferably φ * 90 °. The inventors have also found that a good visual impression can be obtained by having the first dioptric action component an eyesight optimizing eye correction effect for a distance As ^ 1 m of an object from the corneal vertex of the eye and the other dioptric action component has an additional negative astigmatic effect for the eye of the observer for the line of sight, the additional negative astigmatic effect having a cylinder refractive power BK with -1.0 DC ^ BK < -0.125 DC, preferably -0.7 DC ^ BK < -0.3 DC, more preferably BK "-0.5 DC and an axis position φ given in the TABO scheme with -20 ° < φ < 20 °, preferably -10 ° < φ < 10 °, more preferably φ * 0 °. Namely, it has been found by the inventors that this astigmatism described above does not adversely affect the depth of field perceived by an observer. The inventors have recognized that the addition in progressive lenses can be reduced if, in the near zone, they have an additional astigmatism with the above-mentioned effect, which increases the depth of field, while the accommodation-supporting effect remains the same. It is therefore also an idea of the invention that in the optical vision aid the first dioptric power component with respect to an eye of the observer for a distance 25 cm < As ^ 40 cm, preferably As * 33 cm of an object of the corneal vertex of the eye, the best possible corrective effect of a value of -1.0D < ASBK < -0,1 D reduced spherical power has SBK for the line of sight. In an optical vision aid according to the invention, the dioptric effect tuned to the eye of the observer can also be composed of at least two first and two further dioptric components of action. One of the two first dioptric components of action then has an effect for the viewing direction that optimally corrects the eye of the observer for a distance As 1 m of an object from the corneal vertex of the eye. The other of the two first dioptric action components has an effect optimally correcting for the eye of the observer for a distance As ^ 4m of the object from the corneal vertex of the eye for a further viewing direction. In this case, one of the two second dioptric components has an additional negative astigmatic, partially correcting effect for the eye of the observer with a cylinder power BK with -1.0 DC < BK < -0.125 DC, preferably -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and an axis position φ given in the TABO scheme with 70 ° < φ < 110 °, preferably 80 ° < φ < 100 °, particularly preferably φ * 90 ° for the viewing direction. It should be noted, however, that in an optical vision aid according to the invention can also be provided that the matched to the eye of the observer dioptric effect composed of at least two first and two other dioptric components of action, one of the two first dioptric activity components one for the eye of the The observer for a distance As ^ 1 m of an object from the corneal vertex of the eye has the best possible corrective for the line of sight and the other of the two first dioptric components of effect best for the eye of the observer for a distance As ^ 4m of the object from the corneal vertex of the eye Correction effect for a further line of sight and wherein one of the two second dioptric components of action thereby an additional negative astigmatic, partially corrective effect for the eye of the observer with a cylinder power BK with -1.0 DC < BK < -0.125 DC, preferably -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and an axis position φ given in the TABO scheme with -20 ° < φ < 20 °, preferably -10 ° < φ < 10 °, particularly preferably φ «0 ° for the viewing direction. The other of the two second dioptric components in an optical vision aid given above then has an additional negative astigmatic effect for the eye of the observer with a cylinder power BK of -1.0 DC < BK < -0.125 DC, se -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and with an axis position φ given in the TABO scheme with 70 ° < φ < 110 °, preferably 80 ° ^ φ ^ 100 °, particularly preferably φ «90 ° for the further viewing direction or with an axial position φ with -20 ° < φ < 20 °, se -10 ° < φ < 10 °, particularly preferably φ «0 ° for the further viewing direction. In order to determine the parameterization of the visual aid required for an observation person, the invention proposes as a method that from a best possible correction of the eye of the observer for at least a defined distance As of an object from the corneal vertex of the eye for a viewing direction, a first parameterization of optical vision aid is determined. The determined first parameterization is then corrected by an additional dioptric effective component and the correspondingly corrected first parameterization thereon is defined as the desired parameterization. The first parameterization can, for. Example, the determination of the recipe values for the spherical effect, the astigmatic effect and their Achslage and optionally for the prismatic effect and its basis from a subjective and / or objective refraction measurement. In the case of a presbyopic person, the refraction measurement may include not only a far-sighted view of the person (far-end refraction) but also, or alternatively, one or more refraction measurements at different viewing directions and or at different object distances. Preferably, the best possible correction for the eye of the observer is the best possible correction for a distance As ^ 1 m of an object from the corneal vertex of the eye for the line of sight, the additional dioptric component having an additional negative astigmatic effect for the eye of the observer, and wherein the additional negative astigmatic effect is a cylinder power BK with -1.0 DC < BK < -0.125 DC, preferably -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and with an axis position φ given in the TABO scheme with 70 ° < φ < 110 °, preferably 80 ° ^ φ ^ 100 °, more preferably φ * 90 °. However, the inventors have also found that when correcting for the eye of the observer, the best possible correction for a distance As ^ 1 m of an object from the corneal vertex of the eye for the line of sight, wherein the additional dioptric action component is an additional negative astigmatic effect for the eye Eye of the observer, and wherein the additional negative astigmatic effect is a cylinder power BK with -1.0 DC < BK < -0.125 DC, preferably -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and with an axis position φ given in the TABO scheme with -20 ° < φ < 20 °, preferably -10 ° < φ < 10 °, more preferably φ << 0 °, does not noticeably deteriorate the depth of field perceived by the observer. The inventors have recognized that this special astigmatism has a very positive effect on the distribution of astigmatisms in a near field in a progressive lens, because it is associated with a widening of the near field at close range. The determined first parameterization can then also be calculated by a dioptric power component with respect to the eye of the observer for a distance of 25 cm < As < 40 cm, preferably As * 33 cm of an object of the corneal vertex of the eye optimally correcting effect for the viewing direction by the value -1.0 D < ASBK < -0,1 D reduced spherical power SBK be corrected. In addition, the best possible correction for the eye of the observer can then also be the best possible correction for a distance As ^ 4 m of an object from the corneal vertex of the eye for a further viewing direction. Then the first parameterization of the optical vision aid is also determined therefrom and the thus determined first parameterization is corrected by an additional dioptric component of effect. The corrected first parameterization is then defined as the desired parameterization. The additional dioptric power component for the eye of the observer, by which the first parameterization is corrected, is a negative astigmatic effect with the cylinder power BK at -1.0 DC < BK < -0.125 DC, se -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and with an axis position φ given in the TABO scheme with 70 ° < φ < 110 °, preferably 80 ° < φ < 100 °, more preferably φ * 90 °, or with -20 ° < φ < 20 °, preferably -10 ° < φ < 10 °, more preferably φ «0 °. The best possible correction for the eye of the observer may also be the best possible correction for a distance As ^ 4m of an object from the corneal vertex of the eye for the line of vision. The additional dioptric power component may then have an additional negative astigmatic effect for the eye of the observer, the additional negative astigmatic effect for the line of sight being a cylinder power BK of -1.0 DC < BK < -0.125 DC, preferably -0.7 DC < BK < -0.3 DC, more preferably BK "-0.5 DC and with an axis position φ given in the TABO scheme with 70 ° < φ < 110 °, preferably 80 ° < φ < 100 °, more preferably φ «90 °, or with -20 ° < φ < 20 °, preferably -10 ° < φ < 10 °, more preferably φ «0 °. The invention also extends to a computer program with program code means for carrying out the steps of the above-mentioned methods and to a data carrier having such a computer program. In addition, the invention also extends to a computer A program product having program code means stored on a computer readable data memory to perform the steps of the aforementioned methods. In addition, the invention extends to a computer program product which can perform the steps of the aforementioned method via the Internet or comparable networks regardless of the place of detection of the best possible correction of the eye of the observer. An inventive system for determining a desired parameterization of an optical visual aid for an eye of an observer may have a measuring device for determining the best possible correction of the eye accommodated to a predetermined distance (As). Such a system according to the invention then contains a computer unit, to which the best possible correction of the eye accommodated to a predetermined distance (As) can be supplied, determined by the measuring device. The computer unit contains a computer program for determining the desired parameterization (PE) from the supplied best possible correction with a method specified above. An inventive system for determining a sought parameterization of an optical visual aid for an eye of an observer may also include means for displaying optotypes at different distances As from the corneal vertex of the eye of the observer with means for the best possible correction of the eye of the observer in the different distances As included. Such a system also includes a measuring device for determining the distance As from the optician displayed optotype to the corneal vertex of the eye of the observer. Preferably, there is an OLED display in the system for displaying differently sized optotypes for determining the visual strength of the eye of the observer. It is advantageous for the system to have a display which displays the optotypes in the form of letters arranged to words or sentences. In particular, it is advantageous if the system has an actuatable by the observer switching element, which is operatively coupled to a computer unit and which is used for generating an information signal supplied to the computer unit on the depth of field perceived by the observer (ST). Hereinafter, advantageous embodiments of the invention will be described, which are shown schematically in the drawings. Show it: 1 shows a first system for the determination of a parameterization of an optical vision aid with an additional astigmatic effect with respect to the refraction compensation at a defined distance; FIG. 2 is a graph showing experimental values of the depth of field perceived by an observer for various distances through a spectacle lens with an additional astigmatism in relation to the refractive compensation; FIG. 3 is a graph showing experimental values of the depth of field perceived by different observers for different distances through a spectacle lens with an additional astigmatic effect in relation to the refraction compensation; 4a shows a first graph with experimental values for the change in the perception of a change in the depth of field observed by an observer when looking through a spectacle lens with an additional astigmatism for refraction compensation, when the visual acuity is reduced by 0.1 logMAR; 4b shows another graph with experimental values for the change in the visual acuity perceived by an observer when looking through a spectacle lens with astigmatism for refraction compensation when the depth of field is increased by 1D; 5 shows a second system for determining a parameterization of an optical vision aid with an additional astigmatic effect in relation to the refraction compensation in a defined distance range; 6 shows a third system for determining a parameterization of an optical vision aid with an additional astigmatic effect in relation to the refraction compensation in a defined distance range; FIG. 7 shows an optical vision aid with an eyeglass lens tuned to an observer in a side view with an additional astigmatic effect; FIG. 8 shows the spectacle lens of the visual aid in a front view with a near reference point and a distance reference point; FIG. 9 shows the axial position of the additional astigmatic effect in the near reference point according to the TABO scheme; FIG. 10 shows the axial position of the additional astigmatic effect in the distance reference point according to the TABO scheme; and 11a to 11 e show the influence of an additional astigmatic effect on the course of the surface astigmatisms in a progressive lens. FIG. 1 shows a first system 26 for determining a parameterization of an optical vision aid with an astigmatic effect for the eyes 11 that is additional to the refraction compensation at a defined distance A s of an object from the fulcrum vertex of the eyes 11, 11 'of an observer , 11 'of the observer 28. The system 26 comprises a sample goggles 30 with interchangeable trial glasses 31. By inserting suitable sample glasses 31 into the sample goggles 30, a spherical refractive power and a cylinder power as well as a prismatic effect can be set for the left and right eyes 11, 11 'of the observer 28 Corresponding eye 11, 11 'best possible to correct. In the system 26, there is a chin rest 32 to hold the head of the observer 28 therewith. The system 26 further includes a visualization device 34, with which the left and right eyes 11, 11 'of the observer 28 different Sehzeichen 36 can be displayed on an OLED display 38 for display. The system 26 includes a computer unit 42 connected to the OLED display 38 for adjusting the type and size of optotypes on the OLED display 38. The OLED display 38 in the system 26 is received on a rail 40. It is there linearly guided in relation to the chin rest 32 and can be positioned by means of the computer unit 42 with a stepping motor 44 corresponding to the double arrow 45 at several different distances 47 from the eyes 11, 11 'of the observation person 28. For the optotypes displayed on the OLED display 38, different distances A s of the optotypes from the corneal vertex of the eyes 11, 11 'of the observer can thus be displayed. The system 26 thus makes it possible to determine the depth of field ST of the visual impression of an observer 28 for different distances As * 25 cm, As * 33 cm, As * 40 cm, As * 55 cm, As * 66.7 cm, As s 100 cm, As «4 m by this corresponding to the OLED display 38 Optotypes are displayed at different distances As at different parameterizations of the sample goggles 30. The depth of field ST is the difference ST = Ai-A2 of a first distance Ai from a second distance A2 < Ai of the OLED display 38 from the eyes 11, 11 'of the observer 28, where the observer displayed on the OLED display 38 optotypes whose size compared to the maximum visual acuity of the observer is increased by 0.1 logMAR, then the visual acuity is reduced by 0.1 logMAR, just barely recognizable. It should be noted that in healthy people the maximum visual acuity is usually at least 0.0 logMAR. FIG. 2 shows a graph 50 with experimental values for the depth of field ST perceived by an observer 28 through the sample goggles 30 with a different spherical effect of the glasses arranged therein. For a corresponding distance of the curve 52 of the OLED display 38 of the eyes 11, 11 'of the observer 28 cause the glasses of the sample glasses 30 due to their parameterization with the specified on the abscissa spherical effect a complete refraction compensation. The curves 54, 54 'correspond to the depth of field ST perceived by the observer 28 without the additional astigmatism of the lenses. The curves 56, 56 'show the depth of field perceived by the observer 28 in one of the curves 52 underlying dioptric power of the glasses of the sample goggles 30 with an additional astigmatism, the cylinder power -0.5 DC and based on the TABO scheme axis position φ = 0 ° has. The curves 58, 58 'correspond to the depth of field perceived by the observer 28 in one of the curve 52 underlying dioptric We effect the glasses of the sample glasses 30 with an additional astigmatism of the cylinder power -0.5 DC and related to the TABO scheme axis position φ = 90 °. As the graph 50 shows, with the additional astigmatism of the lenses of the trial specimen 30, the depth of field ST perceived by the observer 28 can be increased in the distance range near the eyes of the observer 28, if the additional astigmatism is the cylinder power -0.5 DC and the axis position φ = 90 ° relative to the TABO scheme. At long distances A from the eyes of the observer 28, d. H. A > 1 m, the depth of field ST perceived by the observer 28 is increased with an additional astigmatism of the sample glasses 30 with the cylinder power -0.5 DC and the axis position φ = 90 "related to the TABO scheme. FIG. 3 shows a graph 60 with experimental values of the depth of field ST perceived by different observers 28 at the distances As = 40 cm and As = 500 cm through a sample goggles 30. In addition to a parameterization required for the refraction compensation of the observers 28, 30 glasses were used in the test specimen, which had an astigmatic effect with the cylinder power -0.5 DC and the axis position φ = 0 ° or φ =, respectively, based on the TABO scheme Have 90 °. As can be seen from graph 60, the increase in the depth of field ST associated with the additional astigmatism is different for different observers. However, it can be seen from the graph 60 that, on average, with the additional astigmatism, the cylinder power -0.5 DC and the axial position φ = 90 ° in the vicinity, that is, in the vicinity of the axis. H. small distances As, and the axial position φ = 90 ° for the distance, d. H. great distances As, the perceived depth of field ST of an observer greatly increases. With the system 26, a parameterization of eyeglass lenses 10 for the left and / or right eye 11, 11 tuned to the eyes 11, 11 'of the observer 28 to increase the observation depth for a particular line of sight can be made favorable for an observer 28, z. B. can be determined as follows: First, the head of the observer 28 is positioned in the chin rest 32. Thereafter, the OLED display 38 is moved to a defined target distance, in which the OLED display 38 has a first distance ASi * 33 cm from the corneal vertex of the eyes 11, 11 'defined by an observer 28 on the computer unit 42 Distance range is close. The observer 28 is then used in a first step, the correction, with the best possible correction for this distance is achieved, inserted into the sample goggles. In a second step, the depth of field for the distance As * 33 cm perceived by the observer 28 is determined by moving the OLED display 38 towards the observer 28 until it can no longer recognize the optotype displayed on the OLED display whose size is increased by 0.1 logMAR compared to the maximum visual acuity of the observer, the visual acuity being reduced by 0.1 logMAR. The associated displacement path of the OLED display 38 is then stored in the computer unit 42. Then the second step is repeated for distances As * 36 cm, As * 40 cm, As * 44 cm and As * 50 cm. The values determined for the depth of field are also stored in the computer unit 42. The best possible corrective correction of the observer's eyes for 33 cm with the test specimen 30 is attenuated in each case as follows: at the distance As * 36 cm by 0.25 D, at As * 40 cm by 0.5 D, at As * 44 cm by 0.75 D and with As * 50 cm by 1 D. In a fourth step, the observer 28 in the sample goggles 30 is then used in addition to the correction determined in the first step, an astigmatism -0.5 DC at 0 ° and a spherical glass of 0.25 D in the pro beer goggles, so that the spherical equivalent to the best possible corrective correction found in the first step remains the same. In a fifth step, the second and third steps are repeated thereon and then the data of the depth of field are stored in the computer unit 42. Following this, in a sixth step, in addition to the correction from the first step, the observer 28 is placed an astigmatism -0.5 DC in 90 ° and a spherical glass of 0.25 D in the sample glasses 30, so that the spherical equivalent to the the best possible corrective correction from the first step remains the same. Then the second and third steps are repeated in a seventh step, and then the data of the depth of field are again stored in the computer unit 42. In an eighth step, the data thus obtained are displayed thereon in a graph corresponding to the graph 50 of FIG. In a ninth step, an addition reduction of the correction in the sample goggles 30 is then determined from this graph 50 as follows: The addition of the correction is reduced by the amount at which the depth of field ST of the eye 11, 11 'for the observer 28 still allows a clear image of the optotypes at a distance of As * 33 cm on the abscissa of the count. Alternatively, with the system 26, a parameterization of eyeglass lenses 10, which is favorable for an observer 28, of eyeglass lenses 10 matched to the eyes 11, 1T of the observer 28 can also be determined as follows, for the left and / or right eye 11 perceived by the observer. 11 'increase: First, the head of the observer 28 is positioned in the chin rest 32. The OLED display 38 is then moved to a defined target distance, in which the OLED display 38 has a first distance As * 33 cm from the corneal vertex of the eyes 11, 11 'set by an observer 28 on the computer unit 42 Distance range is close. The observer 28 is then used in a first step, the correction, with the best possible correction for this distance is achieved, inserted into the sample goggles. Then in a second step on the OLED display 38 optotypes are displayed in a different size and thus the eyes 11, 11 'of the observer 28 by inserting different optical glasses 46, 48 with a spherical and / or cylindrical power and / or a prismatic effect in the sample glasses 30 for the distance As corrected. The size of the optotypes is chosen so that their size compared to the maximum vision of the observer 28 is increased by not more than 0.1 logMAR, then the visual acuity is reduced by 0.1 logMAR. The dioptric power required for an eye 11, 11 'for the refraction equalization is then defined in a memory of the computer unit 42 as an initial parameterization PA for a spectacle lens tuned to the corresponding eye 11, 11' and stored in the memory of the computer unit 42. In a third step, then optical glasses 46, 48, which for a corresponding eye 11, 11 'of the observer 28 at a certain distance A have the best possible corrective effect, which the observer 28 through a sample glasses 30 with these glasses 46, 48 determined at the distance As perceived depth of field ST. In a fourth step, an astigmatism with the cylinder power of -0.5 DC and 90 ° axis position is then superimposed with an additional optical element in the sample goggles 30 of the dioptric action of the determined output parameterization PA. Then, in a fifth step, the distance A of the OLED display 38 from the eyes 11, 11 'of the observer 28 is varied by displacing the OLED display 38 on the rail. As a result, the possible shelves of the OLED display 38 are determined by the distance As * 5 m up to which the observer 28 perceives no change in her visual impression with an eye 11, 11 'of optotypes displayed on the OLED displays 38. In this way, the depth of field STu of the visual impression for the distance, i. H. determines the distance range infinity. The determined depth of field STu is then defined as the depth of field of the visual impression of the corresponding eye 11, 11 'of the observer 28 at the distance range infinity and stored in the memory of the computer unit 42. In a sixth step, the OLED display 38 is then moved to a target distance As * 30 cm different from the first target distance As, in which the OLED display 38 has a second distance, which is determined by an observer 28 on the computer unit 42 and corresponding to the proximity range As * 30 cm from the corneal vertex of the eyes 11, 1T of the observer 28 has. In a seventh step, an astigmatism with the cylinder power of -0.5 DC and 0 ° -axis position or 90 ° - is then combined with another optical element in the form of a sample glass with an astigmatic effect in the test specimen 30 of the dioptric action of the determined output parameterization PA. Superimposed axis position. Then, in an eighth step, by displacing the OLED display 38 on the rail, the distance A of the OLED display 38 from the corneal vertex of the eyes 11, 11 'of the observer 28 is varied to determine the possible shelves of the OLED display 38 of FIG the Distance As * 30 cm, up to which the observer 28 perceives no change in her visual impression with an eye 11, 11 ', to determine the depth of field of this visual impression for the distance range proximity. The determined depth of field STn is then defined as the depth of field of the visual impression of the corresponding eye 11, 11 'of the observer 28 at the distance range near and stored in the memory of the computer unit 42. In a ninth step, a parameterization of PF is then defined as the final parameterization for a spectacle lens tuned to the corresponding eye 11, 11 'as follows: The parameterization PF is, with respect to the output parameterization PA, by a spherical effect for the distance range infinity corrected, which corresponds to a reduced by the determined depth of field STu object distance. On the other hand, the output parameterization PA is corrected by a spherical addition for the distance range proximity, which corresponds to an increased object distance by the determined depth of field STN. In addition, a spectacle lens with the final parameterization PF with respect to a spectacle lens with the initial parametrization PA has an additional astigmatism with the cylinder power -0.5 DC and 0 ° -axis position or 90 ° -axis for the distance range proximity and an additional astigmatism with the Cylinder power -0.5 DC and 90 ° axial position or 0 ° axis position for the distance range infinity. In a tenth step, the visual impression of the observer 28 for the final parameterization PF is then checked by displaying this corresponding optotype with the OLED display 38 on both eyes 11, 11 'in different distance ranges. For determining a convenient for an observation person 28 parameterization PF of abge on the eyes 11, 11 'of the observer 28 agreed spectacle lenses 10 for the left and / or right eye 11, 11' in the system 26 are optotypes in the form of words or sentences Strung letters advantageous. The inventors have found that the influence of the reading capability can also be taken into account with this measure. Thus, a high reproducibility of a parameterization PF determined for an observer 28 can be achieved for the method described above. 4a shows a first graph 86 with experimental values for the ratio Q = ^ of the depth of field STM perceived by an observer 28 when observing an object at 500 cm distance through a spectacle lens 10 having a dioptric effect resulting from a first and another dioptric power component, and the depth of field ST0 perceived by the observer 28 when observing the subject through a spectacle lens 10 having a dioptric power produced by the same first dioptric power component and where there is no other dioptric power component. The first dioptric activity component has the best possible corrective effect for the observer 28 in a defined distance range. The further dioptric component corresponds to an astigmatism with the cylinder power BK = -0.25 DC or BK = -0.50 DC or BK = -0.75 DC and the axis position φ = 0 ° or TABO scheme. φ = 90 °. The graph 86 shows how the depth of field perceived by an observer increases when, with additional astigmatism with the cylinder power BK = -0.50 DC and the axis position φ = 90 ° related to the TABO scheme, the visual acuity increases by 0.1 logMAR reduced. Fig. 4b shows in another graph 88 with experimental values the observer's perceived change ΔV of the visual acu V when observing an object at 500 cm distance through a spectacle lens 10 having a dioptric action consisting of a first and a second another dioptric component of activity when the depth of field increases by 1 D. The first dioptric activity component has the best possible corrective effect for the observer 28 in a defined distance range. The further dioptric component corresponds to an astigmatism with the cylinder power BK = -0.25 DC or BK = -0.50 DC or BK = -0.75 DC and the axis position φ = 0 ° or TABO scheme. φ = 90 °. The graph 88 shows that the visual acuity achieved by an observer only worsens only slightly when the depth of field is increased with an astigmatism of -0.5 DC and the axis position φ = 90 ° based on the TABO scheme. FIG. 5 shows a second system 62 for the determination of a parameterization of an optical vision aid with an astigmatic effect for the eyes 11, 11 'of an observer 28 that is additional in relation to the refraction compensation in a defined distance range. The system 62 also includes a sample goggles 30. In the system 62, there is a visualization device 64 having a first display 66 having a display area 67 for displaying optotypes in the distance range infinite at a distance As s 5 m from the eyes 11, 11 'has the observer 28. The visualization device 64 further comprises a second display device 68 with an OLED display 38 for displaying optotypes 36 near the eyes of the observer 28 at a distance As a 30 cm. The OLED display 38 has a pixel density which, at the distance As ® 30 cm from the corneal vertex of the eyes of the observer 28, allows the display of optotypes 36 in a size that allows visual acuity to be determined with the -0.3 logMAR visual acuity. The OLED display 38 is therefore z. For example, an eMAgine SVGA + Rev2 OLED that has 800 x 600 pixels. The display 68 in the system 62 is designed as a reading panel. The display device 68 has a handle 70 with which it from the Observant 28 can be held with one hand. In the system 62, there is a position sensor 72 attached to the head of the observer 28. On the sample goggles 30, a position sensor 74 is fixed. On the display device 68, a position sensor 76 is provided. The system 62 includes a computing unit 42 that communicates wirelessly with the display device 66 and the display 68 as well as the position sensors 72, 74 and 76, e.g. B. by WLAN or Bluetooth. On the handle 70 of the display 68 there is a button 78 designed as a response button. The push button 78 is operatively connected to the computer unit 42. The computer unit 42 is a measuring device for determining the distance As from the optometrist 28 displayed optotypes to the corneal vertex of the eye 11, 11 'of the observer 28. It calculates from the position sensors 72, 74, 76 transmitted position signals, the relative position of the display surface 67th the first display device 66 and the relative position of the OLED display 38 of the second display device 68 to the eyes 11, 11 'of the observer 28. The push button 78 serves to capture the information from the observer 28 for a specific parameterization of the glasses of the sample 30 the perceived depth of field of his visual impression of the optotype 36 displayed with the OLED display. The computer unit 42 can communicate to the observer 28 the distance A s with the pushbutton 78, at which point he or she can sample the goggles 30 on the OLED display 38 displayed optotypes are no longer able to perceive clearly. The system 62 may in principle be operated by the observer 28 or a third person. It thus allows non-contact, automatic and fast without care or guidance of technicians or engineers in particular the measurement of the depth of field and visual acuity of the eyes 11, 1T of the observer 28 in the vicinity. The System 62 may, for. B. be used by an optometrist. It is also suitable for use in clinics, research institutes and medical practices. With the system 62, the eyes of an observer 28 can be measured both monocularly and binocularly. Preferably, the system 62 also includes a docking station 80 for the display device 68, the z. B. for charging an accumulator 83 in the display device 68 is used. It should be noted that the position sensors 72, 74, 76 in the system 62 e.g. B. may be formed as ultrasonic sensors. Alternatively or additionally, it is also possible to provide for the determination of the relative position of the eyes of the observer to the display surface 67 of the display device 66 and the display 28 of the display device 68 optical sensors, which are designed to detect the corresponding distances by means of image evaluation in the computer unit 42 , With the position sensors 72, 74, 76 it is possible, when the observer 28 looks at the OLED display 38 of the display device 68 and when the observer 28 looks at the display surface 67 of the display device 66, both the head position and orientation as well as position and orientation the sample goggles 30 record in a common coordinate system. This allows the creation of individual posture profiles for observers 28 as they look through a spectacle lens. The display 68 may also include a camera 82 located below the reading field for detecting movements of the eyes of an observer 28 when reading. It should be noted that the camera 82 can also be arranged above the reading field. Here, the image sensor of the camera 82 can then be used particularly advantageously for determining the pupil size or act as a so-called eye tracker. It is advantageous if the display device 68 contains a slide-in frame 84 for reading text panels, by means of which the real reading behavior of an observer 28 can be tested out. The function of an eyetracker given above makes it possible to check the gaze behavior. It is also advantageous to provide start-stop buttons in the display device 68, which serve for the quantitative detection of the reading capability of the observer 28. It is also advantageous if the display device 68 includes a slot for one or more color filters. This makes it possible for the observer 28 to view the optotypes or texts displayed on the OLED display 38 through a color filter. In addition, it is to be noted that the display device 68 may optionally also include IR illumination LEDs disposed in the peripheral areas of the display 68 to allow for glare-free illumination of the eyes of the sample end. FIG. 6 shows a third system 92 for determining a parameterization of an optical vision aid with an astigmatic effect which is additional to the refraction compensation in a defined distance range for the eyes 11, 11 'of an observer 28 for a viewing direction. The system 92 includes a measuring device 94, as it z. For example, in the oph-thalmological measuring system i.Profiler® from Zeiss, with which, as described in detail in DE 10 2007 032 001 B4, a laser light beam 97 is applied to the eye 11 of an observation person 28 in a given state of accommodation Retina is projected. With a wavefront measuring device 94, the wavefront of the light of the laser light beam 97 reflected by the retina 96 is detected here and the objective habitual refractive deficit of the eye 11 determined therefrom. The deviation of the waveform of the wavefront from a reference for a non-vision defect measured with the wavefront meter 94 is then considered to be the aberration sought, i. H. determines the deviation of the wavefront from the ideal case. This method is described, for example, in the dissertation by G. M. Spitzlberger " Change of optical aberrations of the human eye by laser in situ keratomileusis " from 2004, to which reference is hereby made in full and the disclosure of which is fully incorporated in the description of the invention, is explained in detail. It should be noted that the system 92 may also include a measuring device 94, as described in DE 10 2007 032 001 B4 in paragraph [0022], for determining refractive power errors of the eye 11 to provide an observer 28 with a laser beam the retina of the eye penetrates through the pupil and with which the retina is scanned. The point of light generated by the laser beam on the retina 96 is then detected here in each case as a reflex on the macula of the eye 11. With the measuring device 94 in the system 92, the habitual refractive deficit of the eye is determined in two accommodation states corresponding to the distance of an object As * 30 cm and As * 5 m from the corneal vertex of the eye 11. In principle, it should be noted that with the measuring device 94 in the system 92, the habitual refractive deficit of the eye 11 can also be determined in more than two accommodative states, e.g. B. Conditions of accommodation which correspond to the different distances As * 25 cm, As * 33 cm, As * 40 cm, As * 55 cm, As * 66.7 cm, As s 100 cm, As s 4 m correspond to the corneal vertex of the eye. In the system 92 there is a computer unit 98 connected to the measuring device 94 with a computer program which calculates a first parameterization PA as an initial parameterization from the accommodation state corresponding to the object distance As * 30 cm from the corneal vertex of the eyes 11, 11 'of the observer 28 , The computer program then corrects this first parameterization PA by an additional dioptric component of effect by superimposing the parameterization PA on an astigmatism with the cylinder power -0.5 DC and 0 ° -axis position or 90 ° -axis position. Accordingly, the computer program calculates in the computer unit 98 from the accommodation state corresponding to the object distance As s 5 m from the corneal vertex of the eyes 11, 11 'of the observer 28 a further first parameterization PA as an output parameterization. The computer program then corrects this further first parameterization PA by an additional dioptric effective component by superposing an astigmatism with the cylinder power of -0.5 DC and 90 ° axial position or also 0 ° axis position on the parameterization PA. The corrected first parameterization PA and the corrected further parameterization PA are then output by the computer program at an output interface 102 of the computer unit 98 as the final parameterization PF of the optical vision aid. FIG. 7 shows a visual aid 6 designed as glasses for the eye 11 of an observer is a spectacle. The optical vision aid 6 contains a spectacle lens 10, which is held in a socket 7 on a spectacle frame 9. The spectacle lens 10 is shown in Fig. 7 in a side view. Through the spectacle lens 10, an observer can see an object 15 in the distance As from the corneal vertex of the eye 11 with a different areas of the spectacle lens 10 passing through the viewing direction A, B sharp. The spectacle lens 10 is a progressive lens. The spectacle lens 10 has a spectacle lens front surface 12 which faces away from an eye 11 of an observer when used as intended, and has a spectacle lens rear surface 14 facing the observer's eye when used as intended. The spectacle lens front surface 12 is here designed as a progressive lens surface. The spectacle lens front surface 12 has a near zone 16 with a near reference point 18 and has a long range zone 20 with a remote reference point 22. The spectacle lens rear surface 14 is presently a prescription surface, d. H. Sphere, cylinder and Achslagen this area were made in accordance with the requirement of a modified according to the above explanations spectacle recipe. FIG. 8 shows the spectacle lens 10 as a part of a spectacle lens blank 8 in a front view. The spectacle lens 10 is designed as a left spectacle lens 10 for the eye 11 of the observer. It has on the eyeglass lens front surface 12 a near reference point 18 in a near zone 16 and a far zone zone 20 with a far reference point 22. Between the near zone 16 and the far zone 20 a progression channel 24 is extended. The dioptric power of the spectacle lens 10 can be converted in the near reference point 18 and in the distance reference point 22 into a plurality of dioptric effective components Ki, K2, K3, K4 having a different refractive power BKN-i, BKN2, BKF1; Disassemble BKF2. In the near reference point 18, the spectacle lens 10 has a dioptric power with the refractive power BKN = BKNi + BKN2. There, the dioptric power of the spectacle lens 10 is composed of a first dioptric effective component K2 having the spherical refractive power BKN1 and a second dioptric acting component K4 having the cylinder refractive power BKN2. The first action component Ki corrects the eye 11 of the observer at near-sighting point 18 for the proximity. Correspondingly, the spectacle lens in the distance reference point 22 has a dioptric power with the refractive power BKF = BKFi + BKF2, which is composed of an action component Ki and a further action component K3. The effect component K-i causes in the remote reference point 22, the correction of the corresponding eye 11 of the observer for the distance. The dioptric components K2, K4 each correspond to astigmatism with the cylinder power -0.5 DC. However, the axis position of the astigmatism of the dioptric components K3, K4 is different. FIG. 9 shows the TABO scheme of the additional astigmatism of the dioptric action component K4 in the near reference point 18. The dioptric action component K4 has the cylinder power BKN2 and the axis position φ = 0 °. FIG. 10 shows the axial position of the additional astigmatism of the dioptric effective component K3 of the dioptric power of the spectacle lens 10 in the distance reference point 22. The dioptric component K3 has the cylinder power BKF2 and the axial position φ = 90 °. The inventors have recognized that the proximity depth of field ST perceived by an observer can be increased by adding to the dioptric power of a spectacle lens optimally correcting the eye 11 of the observer an additional astigmatism with cylinder power -0.5 DC and the TABO scheme related axis position φ = 90 ° is superimposed. Further, the inventors have recognized that the depth of field of view perceived by an observer can be increased by adding to the dioptric power of a spectacle lens optimally correcting the eye 11 of the observer an additional astigmatism with cylinder power -0.5 DC and the TABO scheme related axis position φ = 90 ° or φ = 0 ° is superimposed. In particular, the inventors have recognized that the depth of field perceived by an observer can be increased by adding the above-mentioned additional astigmatism to both the dioptric Effect of a lens optimally correcting the left eye of the observer lens as well as the dioptric effect of the right eye of the observer optimally correcting spectacle lens is superimposed. The spectacle lens rear surface 14 of the spectacle lens 10, which is a prescription surface, has a sphere adapted to the observer, and a cylinder with a certain axis position to produce the additional astigmatism indicated above. In general, the spectacle lens rear surface 14 also has a further cylinder with a certain axial position in order to ensure that, for. B. to compensate for a corneal curvature. FIGS. 11 a to 11 e explain the influence of an additional astigmatic effect on the expansion of the near and far zone 16, 20 and the progression channel 24 in the case of a progressive lens 10. 11 a shows a progressive lens 10 which has a dioptric power adapted to an eye 11, 11 'of an observer 28, which exactly corrects the eye 11, 11' of the observer 28 when looking through the near zone 16 and the far zone zone 20 , The astigmatism of the progressive lens 10 here has the course indicated by the isoastigmatism lines 100. The dioptric effect here does not include additional astigmatism. FIG. 11b shows the progressive lens 10 with a dioptric effective component K1 adapted to the eye 11, 11 'of the observer 28; K3, which optimally corrects the eye of the observer 28 when looking through the short-range zone 16 and the long-range zone 20, wherein in the short-range zone 16 another dioptric effective component K4 namely an additional negative astigmatism with the cylindrical power -0.25 DC and the axial position φ = 0 ° is superimposed. This measure me advantageous widening of the short-range zone 16, wherein the expansion of the long-range zone 22, however, decreases. In FIG. 11c, the progressive lens 10 is shown when the dioptric power component K2 of the dioptric power, which is adapted to the eye 11, 11 'of the observer 28, sees the eye 11, 11' of the observer 28 looking through the short-range zone 16 and In the short-range zone 16, the additional negative astigmatism with the cylindrical refractive power -0.25 DC and the axial position φ = 90 ° is superimposed in the short-range zone 16 as a further dioptric active component K4. Compared to the progressive power lens 10 shown in FIG. 11 a, here the long-range zone 22 is wider and the short-range zone 16 is somewhat narrower. In the case of the progressive lens 10 shown in FIGS. 11 a, 11 b and 11 c, the average dioptrically fully correcting effect is constant in each case in the region indicated by the circle line 21. In contrast, the spherical effect in the progressive lens 10 shown in Figs. 11d, 11e, and 11f is identical in the near zone 16 and the far zone zone 20. In the progressive lens 10 in FIG. 11d, the dioptric power dioptric power component K2 adapted to an observer 28, which optimally corrects the eye of the observer 28 looking through the near zone 16 and the far zone zone 20, is not overlaid with any additional astigmatism. 11 e shows the progressive lens 10 with one of the dioptric action component K 2 adapted to the observer 28 as additional negative astigmatism with the cylindrical power -0.25 DC and the axial position φ = 0 ° superposed on another dioptric component K 4. FIG. 11f shows the progressive lens 10 with one of the dioptric action component K2 of the dioptric power adapted to the observer 28 as a further dioptric effective component K4 overlaid additional negative astigmatism with the cylindrical power -0.25 DC and the axial position φ = 90 ° , 11 e shows that with the additional negative astigmatism with the axial position φ = 0 °, the distance between the isoastigmatism lines with the cylindrical refractive power +0.5 DC and +1.00 DC compared to the progressive addition lens 10 from FIG becomes. It can be seen from FIG. 11 f that, in the case of the additional negative astigmatism with the axial position φ = 90 °, the distance between the isoastigmatism lines with the cylindrical power +0.5 DC and + 1.00 DC compared to the progressive power lens 10 from FIG. 11e decreases. FIGS. 11 a to 11 e show that in the case of a progressive lens 10 which has an additional negative astigmatism in the near zone 16 with the cylindrical refractive power -0.25 DC and the axial position φ = 0 ° and that in the long-range zone 20 an additional negative astigmatism with the cylindrical power -0.25 DC and the axial position φ = 90 °, an advantageous extension of the short-range zone 16 and the long-range zone 20 is made possible. From FIGS. 11 a to 11 e it can be seen that in the case of a progressive lens, therefore, with an additional negative astigmatism with the cylindrical refractive power -0.25 DC and the axial position φ = 0 ° for the proximity and an additional negative astigmatism with the axial position φ = 90 ° for the distance of an observer not only the viewing of the object area with a correspondingly higher depth of field ST can be effected, but also that such a progressive lens due to the greater extent of the near and far zone 16, 20 with the same course of the spherical power also offers improved visual comfort. In addition, it should be noted that a progressive lens 10 having an additional astigmatism described above in the near and Fernbe zone 16, 20, for an observer 28 because of the correspondingly increased depth of field with a progression between distance reference point and near reference point and reduced spherical power may be formed in the near reference point. This measure also results in a correspondingly greater expansion of the near and far zone 86, 88. In summary, the following preferred features of the invention are to be noted in particular: The invention relates to the use of an optical vision aid 6 with at least one spectacle lens 10 by an observer 28 for viewing an object 15. The visual aid 6 has at least one viewing direction A, B matched to an eye 11, 11 'of the observer 28 dioptric action, which is composed of several dioptric activity components Ki, K2, K3, K4. A first dioptric component Κ-ι, K2 of the plurality of dioptric components Ki, K2, K3, K4 has for the eye 11, 11 'of the observer 28 a best possible corrective effect at a defined distance As of the object 15 from the tuft of the eye 11th '11'. At the same time, another dioptric component K2, K4 of the plurality of dioptric components Ki, K2, K3, K4 for the eye 11, 11 'of the observer 28 at the defined distance As has an additional astigmatic, partially correcting effect for the viewing direction A, B. The invention also relates to a method for determining the parameterization of a visual aid 6 suitable for the indicated use as well as a system 26 for determining the parameterization of such a visual aid 6.
