    Field of the invention
    The invention relates to a method for demonstrating the optical properties of a lens of a pair of glasses for an observer. It relates to a demonstration tool comprising a light source and a light sensor, which make it possible to measure the optical properties of glass.
    State of the art
    We know how to produce optical glasses intended to correct an ametropia of the human eye, like myopia, farsightedness or astigmatism. In addition, it is known to provide optical glasses with anti-reflective coatings (AR), for example to reduce the reflected light which could be perceived as irritating by a person looking at a wearer of glasses not having an AR coating. In addition, the AR coating increases the amount of light transmitted through the glass. AR coatings therefore produce two effects: 1) they offer better optical transmission performance and 2) they produce less surface reflections. As there are more and more ways to individualize glasses, the number of options available when choosing glasses is correspondingly increasing. As a result, the task of finding the optimal lenses for a pair of glasses best suited to the wearer's needs is also becoming increasingly complex.
    The interaction between various external parameters required to find the optimal lenses further increases this complexity. For example, spectacle lenses should not only match the wearer's aesthetic preferences, but should also be tailored to the wearer's vision habits and lifestyle. Thus, a spectacle frame must not only be aesthetic, but must also be able to adapt to the lifestyle of the wearer. At the same time, even if a specific frame is desirable for a consumer buying new glasses, the frame may not be suitable for a lifestyle that involves frequent and / or high intensity physical activity.
    Likewise, it is becoming increasingly complex to recommend glasses to a consumer. For example, an ophthalmologist or optometrist not only has the task of determining the refractive error of the eye, the wearing position and the adjustment parameters of the preferred frame, but he must also take into account external parameters, such as vision habits when recommending a particular type of glass. In addition, when choosing a lens, different patients may prefer explanations with different levels of detail with regard to the underlying optical properties of a lens which make it particularly suitable for them.
    Purpose of the invention
    The object of the present invention is to advise a consumer in the choice of a spectacle lens and to educate the persons who recommend or sell glasses by providing a process for demonstrating an optical property of a spectacle lens in using a demonstration tool.
    Presentation and advantages of the invention
    According to one aspect of the invention, a method for advising a consumer in the choice of a spectacle lens consists in: i) obtaining from the consumer information relating to at least one of the consumer's habits in terms of vision and the style of consumer life; ii) provide a demonstration tool comprising a light source and a light sensor for measuring the light emitted by the light source; iii) establish electronic communication between the demonstration tool and a display device; iv) place a spectacle lens between the light source and the light sensor; v) measuring an optical property of the glass; vi) present to an observer the optical property of the glass on the display device; vii) optionally inform the observer of how the optical property could affect at least one of a visual perception, well-being, eye health condition and eye condition of a wearer of spectacle lenses which include the lens; and viii) make a recommendation for the lens, which takes into account the optical property of the lens.
    According to another aspect of the invention, a method of educating an observer on how to demonstrate an optical property of a spectacle lens consists in: i) providing a demonstration tool comprising a light source and a light for measuring the light emitted by the light source; ii) establish electronic communication between the demonstration tool and a display device; iii) place a spectacle lens between the light source and the light sensor; iv) measuring an optical property of the glass; v) present to an observer the optical property of the glass on the display device; and vi) optionally informing the observer how the optical property could affect at least one of a visual perception, well-being, eye health condition and eye condition. a wearer of spectacle lenses which include the lens.

    Description of embodiments
    In a representative embodiment, the method for advising a consumer in the choice of a lens consists in measuring the optical property of the lens in the form of a ratio between the measurement provided by the light sensor when the lens is placed between the light source and the light sensor and when the glass is not placed between the light source and the light sensor.
    In another representative embodiment, an operator places at least one comparison lens between the light source and the light sensor and measures the optical property of the comparison lens. The operator then displays the optical property of the comparison lens next to the optical property of the lens on the display device. In another representative embodiment, the optical property of the lens is compared to the optical property of a lens which is mounted in a frame that the consumer is currently using. The consumer can thus compare a new lens with the performance of the consumer's usual spectacle lens, because the demonstration tool is configured so as to be able to test not only unique lenses, but also spectacle lenses (i.e. say glasses with frame).
    In a particular embodiment, a lens is preselected from a plurality of lenses on the basis of information obtained from the consumer with regard to his habits in terms of vision or his lifestyle. In another particular embodiment, a base material or a glass coating material is preselected based on information obtained from the consumer.
    Generally, the operator displays on the digital display how ultraviolet light (UV) or visible high energy light (HEV) can potentially damage ocular structures and / or compromise the quality of glass in terms of vision . In another particular embodiment, the demonstration tool further includes a model of a human eye. In addition, the display device is generally a tablet, a smart phone or a computer screen. More particularly, the display device is a tablet.
    In a representative embodiment, the optical property is at least either a transmittance of the glass or an attenuation value of the glass. In another representative embodiment, the electronic communication is wireless or wired.
    In a particular embodiment, the demonstration tool comprises a plurality of light sources, in which each light source of the plurality of light sources can be selected separately to measure the optical property. In another representative embodiment, the demonstration tool includes a plurality of light sensors, and each light sensor of the plurality of light sensors can be selected separately to measure the optical property. In yet another particular embodiment, at least one light source is a UV light source or an HEV light source.
    In a particular embodiment, the education of the observer consists at least either of training the observer on how to use the demonstration tool or of informing the observer about the optical property of the glass.
    Referring to the drawings, Figure 1 shows a schematic illustration of a demonstration tool Γ, which is used to demonstrate the optical properties of a lens for an observer. The chassis 2 of the demonstration tool generally houses a battery (not shown). In addition, a processor and / or a computer storage medium can be integrated into the chassis 2. The chassis includes buttons 3 allowing to activate or deactivate the demonstration tool and to select a light source 4 and / or a sensor of light 5. After the demonstration tool has been activated, the light source 4 emits a light beam 6. The intensity of the light beam 6 is measured by the light sensor 5. The measurement provided by the light sensor is stored on the computer storage media. The battery indicator 7 indicates the state of charge of the battery. In addition, in an exemplary embodiment, the demonstration tool has connectors intended for a power supply, a computer and / or a display device. In accordance with the present invention, the term and / or appearing in a list means that at least one item from the list is selected, but any number of items - including all of the items may be present. If fewer elements are selected, and / or should be considered to cover any possible combination or permutation of the selected elements. One or all of the characteristics of the demonstration tool Γ shown in Figure 1 may also be present in the demonstration tool 1 shown in Figure 2, and vice versa.
    Figure 2 shows another exemplary embodiment of a demonstration tool 1, which further includes a model of a human eye 8. More specifically, the model 8 is a sectional representation of a human eye along a vertical plane passing through the center of the lens and through the optic nerve. In an exemplary embodiment, a representation of the optic nerve appears in the semi-cylindrical section 9. The model 8 is therefore in the form of a hemisphere whose interior can be engraved to represent the anatomy of the human eye. Model 8 can in particular be engraved or sculpted to represent ocular structures such as the iris, ciliary body, uvea, sclera, retina, blood vessels, nerves, etc. The level of detail may vary from one model to another. Model 8 is presented to demonstrate how the eye can be affected by light, in particular by ultraviolet (UV) or visible high energy (HEV) light. However, model 8 does not affect the determination of the optical properties of spectacle lenses. In particular, as shown in FIG. 2, the light beam 6 is not incident on the model 8, but can reach the light sensor 5 without being attenuated, that is to say in the same way as the beam light 6 reaches the light sensor 5 in the demonstration tool Γ.
    Figure 3 schematically illustrates a top-down view of the demonstration tool 1 and shows that the sectional plane of the model 8 can be tilted relative to the beam path
    6. The sectional plane is also inclined with respect to a vertical plane perpendicular to the ground and comprising the beam path. However, the specific arrangement of the eye model relative to the frame is not particularly limited, provided that the eye model is arranged so as not to prevent the light beam 6 from reaching the light sensor 5 .
    In FIG. 4, the glass 10 whose performance must be evaluated is placed between the light source 4 and the light sensor 5. If the glass absorbs at least part of the light emitted by the light source 4, a smaller quantity of light reaches the light sensor 5, so that the light sensor delivers a different measurement. By comparing the measurement provided by the light sensor in the absence of glass on the beam path with the measurement obtained when the glass is on the beam path, it is possible to measure an optical property of the glass.
    FIG. 5 represents the demonstration tool 1 in electronic communication with a computer or a display device such as the tablet 11 or the computer station 13. The electronic communication can be wireless or wired communication. Wireless communication includes, without any limitation, Bluetooth® or a Wi-Fi connection. The demonstration tool can be fully controlled by the display device so that the optical property of the glass can be calculated and represented on the device display.
    FIG. 6 represents an exemplary embodiment of a method for advising a consumer in the choice of a spectacle lens. Although the method is shown as a sequence of successive steps 601 to 608, the precise sequence is not a requirement and variations are possible. For example, some steps may be performed in a different order or may be performed more than once. The steps can be carried out sequentially, overlapping (partially) over time or simultaneously. Steps that are performed more than once can be done before, during, or after any of the other steps. In step 601, the consumer contemplating buying new spectacle lenses is asked questions about his vision habits and / or his lifestyle. Some of the questions provide information about the consumer's vision habits and lifestyle. Generally, the person asking the questions is an ophthalmologist or an optometrist. For the sake of simplicity, the person asking the question is hereinafter called an optometrist, even if he is an ophthalmologist. It is also typical that the optometrist performs all of the steps. However, the steps can also be performed by two or more people; for example, an optometrist employee can help set up the demonstration tool.
    Questions regarding consumer vision habits that may be asked by the optometrist include, without limitation, any of the following questions: Do you feel uncomfortable driving at night Are you sensitive to light Do you need to clean your glasses frequently Are you sensitive to glare and sun reflections, for example on reflective surfaces, such as a windshield or a wet road Do you perform tasks that expose you to increased amounts of dust or debris, such as woodworking Do pressure marks appear on your current glasses Do your current glasses slip frequently
    Questions that may be asked about lifestyle include, without limitation, any of the following questions: What is your profession What kind of tasks do you do at home, for example, do you cook and if so, in what proportion. What other tasks do you do Do you go to school or university Will you pursue higher education, such as doctoral studies How do you get around, that is, do you cycle or drive a car or motorcycle What types of digital devices do you use, such as a smartphone, tablet or personal computer How much time do you spend in front of these digital devices What are your hobbies What sports do you practice Do you travel How much time do you spend in the sun
    While the questions are being asked or after, the optometrist provides the demonstration tool 1 or 1 ′ indicated in step 602 of FIG. 6. In the following, the term of demonstration tool 1 designates the tool 1 with the eye model 8 or the demonstration tool Γ without the eye model, unless the eye model is specifically described. If the demonstration tool 1 is not yet activated, the optometrist presses the power-on button 3. In step 603, electronic communication between the demonstration tool 1 and the device is established manually or automatically. Once the electronic communication has been established, the optometrist can control the demonstration tool from the display device.
    The demonstration tool includes at least one light source and at least one light sensor. If only one light source and only one light sensor are provided, the light source is activated and a measured value is delivered by the light sensor. However, if more than one light source is present, the optometrist chooses one. In general, at least one UV light source and one HEV light source are provided. In general, the UV light source can also emit light lying in the wavelength range between 350 nm and 400 nm, more generally between 370 nm and 400 nm, and even more generally in the vicinity of 385 nm. In particular, the HEV light source emits light lying in the wavelength range between 400 nm and 490 nm, more particularly between 400 nm and 450 nm, and even more particularly in the vicinity of 430 nm. In a particular embodiment, the UV light source can be a light emitting diode (LED) emitting light having a wavelength of about 385 nm and the HEV light source can be a LED emitting light having a length of wave of about 430 nm. In another particular embodiment, an infrared (IR) light source is provided. Generally, the IR light source emits light having a wavelength of 750 nm or more.
    If the optometrist has determined that the consumer could benefit from a pair of glasses that notably offer protection against ultraviolet rays, the UV light source is chosen. Likewise, the HEV light source is chosen when the optometrist has determined that the consumer would benefit from glasses offering protection against visible high energy light. In the latter case, the optometrist can show the additional benefit of the HEV light protection glasses also providing UV protection. In a representative embodiment, a light sensor is sensitive to light from more than one light source, such as a sensor sensitive to UV rays and HEV light. However, it is also possible to select a light sensor which is particularly sensitive to the light emitted by the selected light source. Generally, two or more light sensors are provided in the demonstration tool. More generally, two or more light sensors are provided, one of the light sensors being particularly sensitive to UV light and another light sensor is particularly sensitive to HEV light. In another representative embodiment, an IR light sensor is provided.
    As soon as the optometrist has activated either the single light source or the selected light source, a measurement can be obtained from the single light sensor or from the selected light sensor. This measurement value represents a measure of the amount of potentially harmful light, such as UV light, which reaches the eye of the consumer without glasses. In step 604, the optometrist places a lens which protects the eye from UV light on the beam path 6. The light beam reaching the light sensor 5 is now attenuated due to the fact that the lens transmits less light at the wavelength or in the wavelength range emitted by the light source 4. Therefore, the part of the beam path 6 having been transmitted through the glass 10 in FIG. 5 is represented by a dashed line.
    In step 605, an optical property of the glass is measured. For example, the processor of the demonstration tool can calculate the ratio of the measurement obtained by the light sensor when the glass is on the beam path to the measurement obtained by the light sensor when the glass does not is not on the beam path to determine the transmission of the glass at the wavelength or in the wavelength range of the light source 4. Additionally or alternatively it is possible to measure the attenuation value glass at wavelength or in the wavelength range, this value being defined as a transmittance of 100%. For example, the glass placed on the beam path of the demonstration tool in Figure 5 has a transmittance of 67%. Glass could also be described as having an attenuation rate of 33%, i.e. in the example above, 33% of the harmful UV light is prevented from reaching the eye. As indicated above, the memory of the computer, which is a non-transient storage medium readable by computer, stores the measurement provided by the light sensor in the presence and in the absence of the glass on the beam path. However, the measurements can be obtained in any order, i.e. it is allowed, but not required, to obtain the measurement in the first place without the glass being on the beam path .
    In step 606, the display device displays the optical property of the glass 10. In the exemplary embodiment shown in FIG. 5, the glass has a transmission factor of 67%. The display device also makes it possible to display previously measured glasses. In FIG. 5, the display device indicates the transmittance values of two previously measured glasses, which have values of 79% and 42% respectively. In another representative embodiment, three previously measured transmittances can be displayed near the value of the glass currently measured. As a result, the consumer can see a side-by-side comparison of different spectacle lenses within the same active window on the display. In addition, the comparison lens can be a lens of the pair of glasses that the consumer wears when entering the optometrist's shop.
    The optometrist can now inform the consumer, in step 607, of how the optical property could affect at least one of a visual perception, well-being, eye health and an eye condition of a wearer of glasses that include the glass. For example, if glass is particularly suitable for reducing solar glare, the optometrist may open a new window on the display device and show the consumer a side-by-side comparison of two images, one perceived by a wearer of glasses who have the glass with reduced glare, and the other perceived by the same wearer, but with glasses which do not have the same properties of reduction of solar glare.
    In step 608, the optometrist can now make a recommendation for one of the glasses which have been demonstrated using the demonstration tool 1. Unlike a recommendation made without the demonstration tool 1, l The exemplary embodiment of FIG. 6 allows the optometrist to solicit and involve the consumer more. Therefore, the recommendation becomes much less abstract since the consumer can intuitively experience the benefits of a particular glass. In addition, the ability to show other information, such as a side-by-side comparison of images illustrating glare reduction alongside the optical properties of the glass, allows the consumer to better understand why a particular glass is recommended. Other information that can be provided includes, without any limitation, information showing how the lens facilitates reading at different distances, how the lens provides a greater field of vision or how the lens improves the three-dimensional perception of the wearer.
    The optometrist can apply the method of the exemplary embodiment of FIG. 6 as an autonomous process, for example when the consumer has already obtained a prescription to correct his ametropia. In addition, the optometrist can interrupt the task sequence, for example to recommend the design of progressive focus glasses (PAL) or others, and return to the task sequence. In addition, the optometrist can implement the method of the exemplary embodiment of Figure 6 as part of another consultation or an eye examination, so that the method of the example mode of realization becomes part of a sequence of tasks which includes for example the measurement of the refraction of the eye, the determination of the interpupillary distance, a test of sensitivity to the contrast or other processes known to the man of the 'art.
    An optometrist advising a consumer wishing to buy spectacle lenses can use the demonstration tool 1 to make recommendations for a much more efficient, personalized and informative lens. In particular, the process becomes smoother because, although the number of options available for lenses is more important than ever, the optometrist can help the consumer find a subset of lenses that meet all external parameters, all by offering him an important choice. In addition, the consumer can obtain additional information concerning glass, such as how the glass reduces solar glare or improves driving at night, while also discovering the optical properties of glass. The demonstration tool thus brings together all the different aspects necessary for the intuitive choice of a glass.
    In addition, the optometrist advising a consumer can recommend a lens not only for its optical properties, but also by direct comparison with another lens. In addition, the additional information available on the display device makes it possible to highlight the advantages of protection against UV or HEV light, the reduction of solar glare, or the benefits of glass for the individual habits of the consumer. vision material, just to name a few. Thus, the recommendation of lenses is brought to a new level thanks to a relevant combination of optical measurements, information concerning eye health and the expertise of the optometrist.
    In the exemplary embodiment of a method making it possible to educate an observer on how to demonstrate an optical property of a spectacle lens, as shown in FIG. 7, a demonstration tool 1 is used to set up performs steps 602 to 607 as described above with regard to the exemplary embodiment of a method for advising a consumer in the choice of a spectacle lens, as shown in FIG. 6. However , in the exemplary embodiment shown in FIG. 7, the observer is generally not a consumer wishing to buy glasses, but may for example be an optometrist wishing to use the demonstration tool in his business. In addition, the observer can be an optometrist or a salesperson wishing to know more about a particular type of glass. The seller can thus implement the method for educating an observer on how to show an optometrist the optical property of spectacle lenses, as shown in Figure 7. The optometrist can be the observer of the method of the example of embodiment of figure 7, which will be able later to be able to advise a consumer by using the example of embodiment of figure 6.
    The method represented in FIG. 7 enabling an observer to be educated on how to demonstrate an optical property of spectacle lenses allows the observer to discover the optical properties of unknown lenses, that is to say of glasses that the observer did not know, much more quickly and efficiently. In addition, the observer will be able to recommend the glasses more convincingly due to the fact that the observer was able to see directly and in a more illustrative manner how these glasses compare to known glasses.
    Demonstration tool 1 is a powerful aid to better understand the potential health benefits of certain glasses. However, the demonstration tool 1 should not be considered and should not be used as a measuring device providing measured values or technical data for possible future scientific exploitation. Furthermore, the demonstration tool is not a medical device intended to assist an optometrist, an ophthalmologist or any other professional during a medical consultation process.
