[0054] This disclosure may include a recommendation system configured to generate user-specific recommendations for at least one photochromic optical product for a user. The user-specific recommendations may be based on feedback data from the user and performance attributes associated with the photochromic optical product. The recommendation system may generate a compatibility score that quantifies the compatibility of each photochromic optical product with the user's preferences, based on the feedback data (and / or other data described below). This compatibility score may take into account the user's living environment to more accurately determine the most compatible photochromic optical product. The compatibility score may also take into account optical characteristics associated with the user's eye, such as measured optical characteristics, to more accurately determine the most compatible photochromic optical product. In this way, the systems, methods, and computer program products of this disclosure determine which photochromic optical product(s) are best suited for the individual user.

[0055] Reference Figure 1 and Figure 2 Systems 10 and 11 are shown for generating customized recommendations for photochromic optical products for users. The photochromic optical products may include optical products, elements, or devices selected from: ophthalmic products, elements, and devices; display products, elements, and devices; windows; mirrors; or active and passive liquid crystal cell products, elements, and devices. In some non-limiting examples, the photochromic optical product is a lens. Systems 10 and 11 may include a recommendation system 12 communicating with computing device 14 and / or attribute database 16.

[0056] Continue to refer to Figure 1 and Figure 2The computing device 14 may include a display and input devices (e.g., a keyboard, touchscreen, etc.) to allow a user (e.g., a consumer of photochromic optics) to input data into the computing device 14, which can then be passed to the recommendation system 12. The computing device 14 may be a user-owned computing device, such as a smartphone, tablet, or other mobile or non-mobile computer. The computing device 14 may also be an in-store kiosk or other computing device 14 located at a merchant's location, such as a retail location or optometrist's office associated with photochromic optics.

[0057] Data input to computing device 14 and transmitted to recommendation system 12 may include location data. This location data may include geographic locations associated with the user, such as locations where the user resides or spends sufficient time (e.g., on vacation, at a second home, on a business trip, etc.). User location data can be input into computing device 14 by the user entering a location name, associated coordinates, identifying the location on a map displayed on the computing device, or other sufficient means. User location data may be generated by computing device 14 based on GPS data or other location data collected by computing device 14. Multiple locations may be input as location data. User location data may be input into computing device 14 in response to a questionnaire requesting data on the locations(s) associated with the user.

[0058] Continue to refer to Figure 1 and Figure 2Recommendation system 12 can use location data to determine the living environment associated with a user. This living environment may include at least one of the following: outdoor air temperature, radiation exposure, or a combination thereof, that the user is expected to experience at the location associated with them. Radiation may include at least one of UVA, UVB, blue light, visible light, infrared light, or any combination thereof. The living environment of the user's location can be determined by testing and / or based on known statistical data for that location. Databases and modeling software such as Cesora, Solargis, or the National Renewable Energy Laboratory (NLRE) can be used for this purpose. Therefore, the user's daily, weekly, monthly, quarterly, or annual exposure to UVA, UVB, blue light, visible light, infrared light, temperature, etc., can be determined. The average values ​​of these factors over a year, and / or their average values ​​over a portion of the year, can be considered. For example, the average maximum outdoor air temperature of a location over 12 months of the year can be used. The average maximum outdoor air temperature over a portion of the year (such as the hottest or coldest months of the year, March, April, May, June, July, August, September, October, or November) can also be used. The highest average outdoor air temperature can be used for the whole year or a part of the year to more closely represent daylight temperatures, which are the temperatures at which photochromic optics darken due to exposure to photochemical radiation. Furthermore, the difference between the highest outdoor air temperatures of the warmest eight months and the annual average highest outdoor air temperature can help distinguish between more consistent demand in coastal areas and greater temperature variation demand in inland areas. The type of average outdoor air temperature for that location to be considered during recommendation generation can be chosen based on any number of other factors.

[0059] The data input into computing device 14 and transmitted to recommendation system 12 may include lifestyle data. Lifestyle data may be input in response to questionnaires inquiring about the user's lifestyle. Lifestyle data may include factors such as time spent outdoors or indoors, occupation, the user's usual activities / hobbies, usual travel destinations, or other information indicating environments where photochromic optics may be used.

[0060] The data input to computing device 14 and transmitted to recommendation system 12 may include feedback data associated with user preferences in response to questionnaire data. Computing device 14 may be configured to display questionnaire data associated with performance attributes of photochromic optics. This questionnaire data may include questions associated with the relative importance set by the user for each performance attribute.

[0061] Non-limiting examples of such performance attributes include at least one of the following: outdoor darkness, indoor transparency, rate of darkening, rate of transparency, indoor blue light protection, outdoor blue light protection, UV radiation protection, reactivity under indirect sunlight, time-based performance, in-vehicle activation, and color consistency. Table 1 below describes each performance attribute and the tests associated with determining each performance attribute.

[0062]

[0063] The following provides the test protocols associated with the test methods listed in Table 1.

[0064] Indoor Transparency Testing: In each test, photochromic optics were pretreated to achieve a completely unactivated state by activating them with a 365nm UV lamp for 5 minutes, then heating them to 70°C and exposing them to a yellow fluorescent lamp for 25 minutes, followed by storage in darkness for at least 1 hour. Decolorized phototransmittance % was read using Hunter UltraScan Pro. As used herein, phototransmittance % refers to the spectrally weighted transmittance associated with visual perception under adequate light conditions, as defined by the 1931 CIE photometric function.

[0065] Outdoor darkness combination test: The photochromic optics were activated for 15 minutes in two 150W xenon arc lamp optical platforms with 50:50 beam splitters. UVA / VIS was provided through a KG2 filter, and a second beam with both a KG2 and a GG400 filter produced only supplemental VIS, providing 50 klux of VIS and 6.7 W / m². 2 UVA. Photopic transmittance was measured using a Zeiss M601 spectrophotometer after activation at 23°C and 35°C for 15 minutes.

[0066] Indirect sunlight testing: The activation method for photochromic optics is similar to that of outdoor dark-light combination testing, except that a Schott 320nm LP filter is used instead of the KG2 filter and an Asahi 395nm LP filter is used instead of the GG400 filter to provide a closer match to UVA at 6.6W / m. 2 Furthermore, the VIS is the irradiance spectrum curve for non-direct illumination at 30 klux. The photopic transmittance was measured using a Zeiss M601 spectrophotometer after activation at 30°C for 15 minutes.

[0067] Transparency rate combination test: As described above, the photochromic optics were activated in an outdoor dark test at 23°C, then the activation shutter was closed and transmittance was collected over time to determine when the visible transmittance reached 70%T at 23°C. If the measurement taken at a specific time did not accurately record 70%T, linear interpolation between two adjacent data points was used to derive the time to reach 70%T. Using the same irradiance as in the outdoor dark test described above, the photochromic optics were activated at 10°C for 15 minutes, and the fading was collected after 30 minutes, at which point the visible transmittance was recorded.

[0068] Darkening Rate Test: As described above, the photochromic optics were activated in an outdoor darkness test at 23°C, and the percentage of visible transmittance was recorded over time to determine when 18%T was reached. During activation, if a measurement taken at a specific time did not accurately record 18%T, linear interpolation between two adjacent data points was used to derive the time to reach 18%T. This 18%T represents the darkness of a Category 3 lens.

[0069] Indoor blue light test: When the test is conducted at 23°C as described above, the spectrum in 5nm increments is weighted in the range of 280-460nm from the first data measurement before the activation shutter is opened, according to the weighting function in Table B-1 of ISO8980-3, and the integral sum is reported.

[0070] Outdoor blue light test: When the test is conducted according to the above 23°C test, the spectrum is weighted in 5nm increments starting from the spectrum 15 minutes before the shutter of the active beam is closed, according to the weighting function in Table B-1 of ISO 8980-3, and the integral sum is reported.

[0071] UV blocking test: After preprocessing the optical articles reported above as described above, the spectra measured on the Cary 4000 spectrometer in 5 nm increments are weighted according to the weighting function in Table B-1 of ISO 8980-3 for UVB in the 280-315 nm range and UVA in the 315-380 nm range, and these integral sums are reported.

[0072] Time-based testing: As reported above, this combined indoor transparency testing and testing in water at 100°F with a single 300W xenon lamp featuring a KG2 filter at 18W / m. 2 UVA was used to pretreat photochromic optical products. Changes in photosensitive light density (absorbance) were recorded. The photochromic optical products were then exposed to an Atlas Ci5000 aging tester at 340 nm at 0.25 W / m². 2The lenses were exposed continuously for 65 hours. They were then pretreated again and measured again on a single lamp stand. The percentage loss of optical density (%) was calculated as the difference between the initial change in optical density and this change after exposure, divided by the initial change in optical density.

[0073] In-vehicle testing: As reported above, the photochromic optical products were pretreated in conjunction with indoor transparency testing and activated using a 150W lamp on an A-BMP. The KG2 filter and windshield filter were positioned appropriately, and the irradiance was adjusted to 1.0W / m² integrated between 380-420nm. 2 The transmittance was 1.7 klux at 27°C. The windshield consists of two 2.3 mm solar green glass panels, with Solutia-UV reinforced polyvinyl butyrate as the laminating material. The visible transmittance after 15 minutes of activation was reported as %.

[0074] Color consistency test: a* and b* color coordinates were recorded over time increments during activation and fading at 23°C, and each region was pixelated. Using the Wavemetrics procedure, which distinguishes merged regions from outer regions, the pixelation of the merged region was reported to provide figures consistent with the total merged region (with straight lines enclosing the start and end points of fading over 30 minutes).

[0075] In response to the questionnaire data, the user can input feedback data into the computing device 14. The feedback data may include user preferences regarding the relative importance of various performance attributes. The computing device 14 can then transmit the feedback data to the recommender system 12.

[0076] Feedback data, including the relative importance of various performance attributes, can be indicated by responding to specific questionnaire data from the recommender system 12. Relative importance can be indicated by users ranking each performance attribute relative to one another, such as by sorting performance attributes from most important to least important (or vice versa), and / or by assigning numerical importance to each performance attribute (e.g., importance on a scale of 1-100). Relative importance can also be indicated by users indicating which performance attributes are important to them and / or which are not.

[0077] Continue to refer to Figure 1 and Figure 2The data input to computing device 14 and transmitted to recommendation system 12 may include user eye data. This user eye data may include data associated with the optical characteristics of the user's eyes. Optical characteristics may include the shape and / or size of the user's eyes or the user's eye or visual glare sensitivity. User eye data may be input to computing device 14 in response to a questionnaire asking about the user's eyes. User eye data may include eye sensitivity data associated with the user's sensitivity to certain types of radiation or situations involving the user's exposure to radiation. For example, eye sensitivity data may include data on the user's sensitivity to bright sunlight, night driving, bright indoor light, light from the computing device's display, transitions from indoor light to outdoor light, or transitions from bright to dark environments (and vice versa). Sensitivity questionnaires can be used to determine glare sensitivity, such as by using the De Boer scale (1967) to determine the user's sensitivity to glare, ranging from "unbearable" to "just perceptible." Glare sensitivity can be assessed using ophthalmic devices such as the Luminous Acuity Tester (BAT) (available from Marco Ophthalmic) to assess functional visual acuity and visual acuity recovery in bright light conditions, and / or wearable devices such as Lumiz. TM The Essilor instrument (100) objectively quantifies the eye's sensitivity to light by simultaneously testing both of the user's eyes and determines the light sensitivity threshold under different lighting conditions. Data input to the computing device 14 and transmitted to the recommendation system 12 may include user demographic data. User demographic data can be input to the computing device 14 in response to questionnaires inquiring about the user's demographics. User demographic data may include age, gender, eye color, etc.

[0078] Continue to refer to Figure 1 and Figure 2 The computing device 14 can transmit location data, lifestyle data, feedback data, user eye data and / or user demographic data to the recommendation system 12, which can generate customized photochromic optical product recommendations for the user in response and at least in part based on the received data, as described below.

[0079] Continue to refer to Figure 1 and Figure 2The attribute database 16 can store data associated with performance attributes of multiple photochromic optical products. The data associated with performance attributes can include data on the quantified performance attributes exhibited by the photochromic optical products, measured and / or calculated. The data associated with performance attributes can be determined through the aforementioned laboratory and / or field tests corresponding to various performance attributes. The attribute database 16 can store this data associated with the performance attributes of each corresponding photochromic optical product.

[0080] The attribute database 16 may also include historical feedback data associated with responses (e.g., feedback data) to previously described questionnaire data related to the relative importance of various performance attributes.

[0081] The feedback data received by the recommendation system 12 from the user's computing device 14 can be stored in the attribute database 16 as further historical feedback data, so that as more user-specific data is received over time, the historical feedback data will also increase. This allows the recommendation system 12 to adjust its recommendations over time as more feedback data accumulates.

[0082] Continue to refer to Figure 1 and Figure 2 The recommendation system 12 can determine multiple performance attributes for each of a plurality of photochromic optical articles. Determining multiple performance attributes may include the recommendation system 12 receiving (e.g., passively receiving or actively retrieving) data associated with the performance attributes from the attribute database 16. Determining multiple performance attributes for each of the plurality of photochromic optical articles may also include the recommendation system 12 parsing and / or analyzing the data received from the attribute database 16.

[0083] In response to determining these performance attributes, recommender system 12 can generate a compatibility score for each of the multiple photochromic optics. The compatibility score can initially be determined at least in part based on historical feedback data (from other users) of previously described questionnaire data associated with the relative importance of the various performance attributes, or it can be determined solely based on user feedback data without considering historical feedback data. Historical feedback data can be used to generate initial relative weights associated with the various performance attributes based on how historical users weighted them. Initial weights can be generated using all or only a portion of historical feedback data. This segment of historical feedback data can be associated with similar users of the current user for whom recommendations are being generated, such as users with similar location data, lifestyle data, feedback data, user eye data, and / or user demographic data. These initial weights can be used to generate an initial compatibility score based on an algorithmic approach to the results of using the various performance attributes exhibited by the photochromic optics. This initial compatibility score can be used to generate a user compatibility score by including user-specific feedback data in the algorithm, which illustrates specific user preferences regarding performance attributes (e.g., compared to historical feedback data). User-provided feedback data can be used to generate relative weights and / or adjust the initial weights associated with various performance attributes so that the algorithm's results (such as compatibility scores) reflect the user preferences provided by the feedback data.

[0084] Reference Figure 2 The compatibility score can be further modified based on the location data received by the recommendation system 12. Based on this location data, the recommendation system 12 can determine the user's associated living environment. Based on the determined user living environment, the recommendation system 12 can communicate with a climate database 30, which stores data related to the performance of each of a plurality of photochromic optical products in a specific geographic region and / or climate.

[0085] The performance of each of several photochromic optics in a specific region or climate can be determined by testing the various photochromic optics under real outdoor environmental conditions in different regions and / or climates. As used herein, a region refers to a geographical location. A geographical location can be of any size, depending on the specificity of the environmental conditions to be determined. For example, the region can be as small as a city block or as large as a continent. A region can refer to a village, city, state, country, group of countries, a specific area within a continent, or any other geographic spatial region. A region can also refer to neighboring countries or intercontinental regions that have similar environmental conditions. A region can also refer to a geographic area with the same global latitude or longitude. A region can also refer to a geographic area with the same elevation. As used herein, climate refers to the average weather conditions of a region over a long period of time. For example, climates can be classified as tropical, arid, temperate, continental, polar, etc. As used herein, environmental conditions refer to conditions associated with climate. Non-limiting examples of environmental conditions include outdoor air temperature, percentage humidity, time of day, albedo, sky conditions, global irradiance, directional irradiance, air pressure, precipitation, wind, or any other measurable climate variable or combination thereof.

[0086] Sky conditions in the region can include clear, cloudy, partially cloudy, rainy, snowy, foggy, dark, or any combination thereof at the time of testing. Outdoor air temperature can include the average outdoor air temperature for the entire year or a portion of the year. Average outdoor air temperature can include the average maximum outdoor air temperature for the hottest or coldest months of the year (3 to 11 months). For example, average outdoor air temperature can include the average maximum outdoor air temperature for the hottest or coldest months (4 to 10 months). For example, average outdoor air temperature can include the average maximum outdoor air temperature for the hottest or coldest months (5 to 9 months). For example, average outdoor air temperature can include the average maximum outdoor air temperature for the hottest or coldest months (6 to 8 months). Global irradiance can be measured by placing a six-inch (15.2 cm) sphere on a spectroradiometer, which has a near-ideal cosine response and can measure almost a full 180° angle. Irradiance can also be measured using a sphere placed directly towards the sky on a horizontal plane approximately three feet (0.91 meters) above the ground. Global irradiance can non-exclusively include global irradiance in the range of 360 nm to 430 nm. Directional irradiance can be measured using a two-inch (5.1 cm) integrating sphere placed on a spectroradiometer. The sphere's measurement range is approximately ±45° of the port normal. Directional irradiance can include directional irradiance in the range of 360 nm to 430 nm.

[0087] When testing photochromic optics to determine the environmental conditions of a region and the performance of the photochromic optics under those conditions, these variables can be recorded during testing. The recorded data can be used to determine both the characteristics of the photochromic optics under test and the typical environmental conditions of the region.

[0088] Various photochromic optics can be tested in any number of regions or climates worldwide to determine their performance in different types of environments with the desired degree of specificity. Photochromic optics can be tested in any number of regions at different latitudes, longitudes, or altitudes. Photochromic optics can be tested in any number of geographical areas listed above. For example, photochromic optics can be tested in cities (or other areas) where users typically use them and are subjected to varying degrees of irradiance reflection from surrounding buildings or trees.

[0089] Referring to Figures 3A to 3C, the performance of photochromic optical products in a specific region or climate can be determined by generating an outdoor temperature and an average directional irradiance of 360–430 W / m² for each optical product. 2 The percentage of visible transmittance is determined using a chart that includes a band of visible transmittance % for each lens. The visible transmittance % can be determined for each photochromic optics based on the tests described above. The visible transmittance % can also be determined based on a predictive model. Therefore, each product has a specific optimal performance range to ensure that the product is neither too bright nor too dark under viewing conditions.

[0090] The prediction model may be based on at least one of the following: incident irradiance of the optical product facing at least one direction, surface temperature of the optical product facing at least one direction, spectrum of the optical product facing at least one direction, global irradiance of the region, environmental conditions of the region, or any combination thereof.

[0091] As used herein, incident irradiance refers to the irradiance acquired through a two-inch (5.1 cm) integrating sphere collinearly facing the optical object. Irradiance measurements can be performed using any adequate means. Irradiance measurements can be performed using a spectroradiometer, such as the OL-756 spectroradiometer which records data in the 200–800 nm range, and can be used to determine spectral data of radiation, such as UVA, UVB, UVC, visible light, and radiation for activation in the 360–430 nm range. To determine the global irradiance of the region, a six-inch (15.2 cm) global acquisition sphere can be placed on the spectroradiometer. After allowing the spectroradiometer to warm up appropriately and to be fully calibrated according to the manufacturer's instructions, global irradiance measurements can be performed and recorded. Several global irradiance measurements of the region can be performed at intervals of short or long relative to each other. To determine the incident irradiance of each photochromic optics being tested, a six-inch (15.2 cm) collecting sphere can be removed and replaced with a two-inch (5.1 cm) collecting sphere. The incident irradiance of each optics in at least one direction can then be measured using a spectroradiometer. The incident irradiance of the photochromic optics can be taken after the optics have completely darkened due to photochemical radiation exposure under outdoor conditions.

[0092] As used herein, surface temperature can be measured by bringing an infrared thermometer close to an optical object facing at least one direction. The infrared thermometer can be held a few inches away from the optical object, such as 1–12 inches (2.5–30.5 cm), 3–9 inches (7.6–22.9 cm), or 4–6 inches (10.2–15.2 cm), and the temperature can be determined and recorded.

[0093] As used in this article, the spectrum can be determined using a spectrometer. A spectrum refers to the light transmitted through a lens facing at least one direction, within the visible wavelength range (380-800 nm).

[0094] Multiple incident irradiance, surface temperature, and spectrum can be determined for each optical product, where the optical product faces different directions (e.g., towards the sun, away from the sun, etc.).

[0095] This prediction model can generate a predicted photosensitive transmittance % based on input outdoor temperature and average directional irradiance (such as directional irradiance in the 360-430 nm range). (For example, based on the data shown in Figures 3A to 3C, the photosensitive transmittance % can be expressed as a function of outdoor temperature and average directional irradiance.) This model allows prediction of the photosensitive transmittance % of an optical product based on outdoor temperature and average directional irradiance in any region (even untested regions) to determine if the optical product is suitable for that region. Statistical software can be used to generate this prediction model. The prediction model can show the target photosensitive transmittance % of a photochromic optical product based on certain combinations of outdoor temperature and directional irradiance, such that a target of 5%-50% photosensitive transmittance, such as 10%-20%, 10%-15%, 15%-20%, 5%-25%, or 5%-20%, is expressed as a function of outdoor temperature and directional irradiance. The photosensitive transmittance % is based on the darkening of the optical product due to exposure to photochemical radiation.

[0096] Referring to Figures 3A to 3C, outdoor temperature and average directional irradiance (W / m²) are shown for several different photochromic optical products (lenses 1-3). 2 An exemplary chart is provided. This chart includes bands (white areas) indicating that the visible transmittance % for each of lenses 1-3 is between 10% and 20%, to indicate the conditions under which each particular lens might be suitable for the user's outdoor temperature and average directional irradiance at 360nm-430nm. In this non-limiting example, the 10%-20% visible transmittance % is assumed to be within the user's comfort range, although this range can be adjusted. As can be seen in Figures 3A to 3C, the white bands for lenses 1 and 2 indicate that these lenses may be more suitable for areas or climates associated with lower outdoor temperatures, while lens 3 may be more suitable for areas or climates associated with higher outdoor temperatures. These predictions of visible transmittance % for various photochromic optics can be stored in a climate database 30 (from...). Figure 2 It is used to modify the compatibility score.

[0097] Therefore, based on the above tests, the performance of each of the multiple photochromic optical products in a specific region or climate can be determined. Based on the user's living environment and the performance of each of the multiple photochromic optical products in regions or climates similar to the user's from the climate database 30, the recommendation system 12 can adjust the compatibility score to provide the user with more suitable photochromic optical product recommendations.

[0098] The compatibility score can be further modified based on the lifestyle data received by the recommendation system 12. For example, for users who spend more time outdoors, the recommendation system 12 can adjust the compatibility score based on the user's expected increase in exposure to photochemical radiation, corresponding to optical products that provide darker characteristics (better radiation protection) when exposed to such radiation. Therefore, optical products can be recommended to users at least in part based on their lifestyle data.

[0099] The compatibility score can be further modified based on the user's eye data received by the recommendation system 12. For example, a user who is highly sensitive to glare may be most comfortable and / or efficient when selecting a visual transmittance level lower than that typically required in their living environment, such as 15%-20% instead of 20%-25%, 10%-15% instead of 15%-20%, and 5%-10% instead of 10%-15%. Therefore, optical products can be recommended to users at least in part based on user eye data.

[0100] The compatibility score can be further modified based on the user demographic data received by the recommendation system 12.

[0101] Based on the compatibility scores generated by the recommendation system 12, the recommendation system 12 can generate recommendations including at least one of a plurality of photochromic optical products. The recommendation system 12 can provide a user with the most compatible photochromic optical products(s), thus customizing recommendations for that user. The recommendation system 12 can transmit the recommendations to the computing device 14. The transmitted recommendations may include the product(s) names associated with the most compatible photochromic optical products(s). The transmitted recommendations may include more detailed results showing the compatibility scores associated with each of the plurality of photochromic optical products. Based on the received recommendations, the user can view further information about the recommended photochromic optical products(s) (and non-recommended photochromic optical products) and can initiate transactions, such as payment transactions, for desired and / or recommended photochromic optical products.

[0102] Reference Figure 4 This illustrates a method 20 for generating customized recommendations for photochromic optical products for users. In a first step 22, method 20 may include a recommendation system 12 (from...) Figure 1 and Figure 2 In the second step 24, the recommendation system 12 can determine multiple performance attributes for each of a plurality of photochromic optical products. Figure 1 and Figure 2The system receives feedback data associated with each of the multiple performance attributes. In the third step 26, based on the multiple performance attributes and the feedback data, the recommendation system 12 can generate a compatibility score for each of the multiple photochromic optical products. In the fourth step 28, the recommendation system 12 can generate a user-specific recommendation including at least one of the multiple photochromic optical products based on the compatibility scores for each of the multiple photochromic optical products.
