DETAILED DESCRIPTION OF THE INVENTION

[0014] This embodiment will be described in detail below. The retinal sensitivity adjusting member providing device 100 of this embodiment outputs a retinal sensitivity adjusting member selected based on input user design information. The user of this embodiment is a customer who is planning to purchase lenses at a store selling eyeglasses, etc.

[0015] Fig. 1 is a block diagram showing an example of the system configuration of a retinal sensitivity adjusting member providing system 10 according to the first embodiment. As shown in Fig. 1, the retinal sensitivity adjusting member providing system 10 includes a retinal sensitivity adjusting member providing device 100 and a design device 200 connected via a network N. Note that the design information database stored in the design device 200, which will be described later, can be stored in the retinal sensitivity adjusting member providing device 100, thereby making the design device 200 unnecessary.

[0016] The retinal sensitivity adjusting member providing device 100 shown in FIG. 1 is a device such as a smartphone terminal, tablet terminal, or personal computer owned by a user or assigned to a store selling eyeglasses, an eye clinic, or the like. The retinal sensitivity adjusting member providing device 100 has an interface, for example, as shown in FIGS. 10 to 13 described below. The interface allows input of effect information related to the effect desired by the user, light source information for the visual environment that is affected to obtain the effect, and subject movement information in the visual environment. The interface also displays the designed retinal sensitivity adjusting member and recommended usage information for the retinal sensitivity adjusting member. In this embodiment, the retinal sensitivity adjusting member will be described using eyeglass lenses as an example.

[0017] 1 can be configured as a computer including a CPU, RAM, and a ROM that stores programs and various data for executing each processing routine described below. Because the retinal sensitivity adjusting member providing device 100 and the design device 200 are basically general computer configurations, the retinal sensitivity adjusting member providing device 100 will be described as a representative.

[0018] For example, the retinal sensitivity adjusting member providing device 100 can be realized by a computer 180 shown in Fig. 2. The computer 180 includes a CPU 181, a memory 182 as a temporary storage area, and a non-volatile storage unit 120. The computer 180 also includes an input / output interface (I / F) 184 to which an input / output device or the like (not shown) is connected, and a read / write (R / W) unit 185 that controls reading and writing of data from and to a recording medium. The computer 180 also includes a network I / F 186 that is connected to a network such as the Internet. The CPU 181, memory 182, storage unit 120, input / output I / F 184, R / W unit 185, and network I / F 186 are connected to one another via a bus 187.

[0019] The storage unit 120 can be realized by a hard disk drive (HDD), a solid state drive (SSD), a flash memory, etc. The storage unit 120 as a storage medium stores data that can determine an association between a lens and recommended lens usage information, and a program for causing the computer 180 to function. The CPU 181 reads the program from the storage unit 120, loads it into the memory 182, and sequentially executes the processes contained in the program.

[0020] The above is an explanation of an example of the electrical configuration of the computer in FIG.

[0021] Here, the storage unit 120 stores selection candidates for effect information, light source information, and subject movement information.

[0022] It should be noted that the effect information, light source information, and subject mobility information are not limited to being stored in the storage unit 120. In the present embodiment, as shown in Figures 10 to 13, such information needs to be stored in advance in the storage unit 120 because a user, a doctor, or a clerk at a store selling lenses selects and inputs the information stored in the storage unit 120. However, if the information is input by a user, a doctor, a clerk, or the like without being selected and input, the information does not need to be stored in advance. Furthermore, the effect information, light source information, and subject mobility information are not limited to being stored in the storage unit 120 of the retinal sensitivity adjusting member providing device 100, and may be stored in the storage unit 220 of the design device 200.

[0023] Furthermore, the input information may be stored in the storage unit 120, or some or all of the information may be deleted or anonymized before being stored. The information may also be encrypted before being stored. The information stored in the storage unit 120 includes information that is temporarily stored. That is, the effect information, light source information, and object mobility information input by a user or the like are temporarily stored, and the information is transmitted to the design device 200. After transmission, the effect information, light source information, and object mobility information are deleted.

[0024] Here, the effect information, light source information, subject movement information, and recommended use information will be described with reference to FIGS. 3A to 3C. The effect information is information about the effect desired by the user of the lenses, such as "to make reading easier," "to sleep better," "to wake up refreshed," "to drive more easily," etc., as shown in Figure 3A.

[0025] The light source information is information related to the light source information of the visual environment that is affected to achieve the effect desired by the user. For example, as shown in FIG. 3B, if the effect desired by the user is to make text easier to read when reading, the information is information such as whether the light source information of the visual environment in the room where the user reads is "LED" or "sunlight." If the effect desired by the user is to "sleep," the information is information such as whether the light source information of the visual environment in the bedroom or the room where the user mainly stays before sleep is the type of lighting source, for example, "LED."

[0026] The object mobility information is information about the movement of the object, such as whether the object viewed using the lens is dynamic or static. For example, as shown in FIG. 3C , the information is information about whether the object viewed using the lens is primarily dynamic or static, based on the user's living environment, work, etc. Note that the object mobility information is not limited to selection by the user, but may be selected in accordance with the selected effect information. That is, if "reading" is selected as the effect information, "still" may be selected because the object mobility information represents a stationary book, etc. Furthermore, if "driving a car" is selected as the effect information, "dynamic" may be selected because the object mobility information represents a moving car, scenery, passersby, etc.

[0027] The recommended use information is information that recommends situations other than the effect information desired by the user in which the lenses designed (selected) based on the user design information determined from the effect information, light source information, and subject movement information (hereinafter also referred to as "user design information") can be suitably used. The recommended use information is information that is predetermined based on the effect information, light source information, and subject movement information. For example, as shown in FIGS. 3A to 3C , when the effect information is "reading," the light source information is "LED," and the subject movement information is "stationary," "display work," "art appreciation," "study," etc. are extracted. When the effect information is "driving a car," the light source information is "sunlight," and the subject movement information is "dynamic," "outdoor sports" is extracted. When the effect information is "driving a car," the light source information is "LED," and the subject movement information is "dynamic," "indoor sports" is extracted. By determining the recommended use information in this way and displaying it to the user, the user can see that the lenses can be suitably used in various situations. Another advantage is that it becomes easier for users to select a lens that can be used in a variety of situations rather than a lens that can be used in only one situation.

[0028] Note that the effect information, light source information, subject movement information, and recommended use information are not limited to those shown in Figures 3A to 3C, and other information may be included, or it may not be necessary to include all of the information shown in Figures 3A to 3C.

[0029] Below, we will explain each processing unit in the retinal sensitivity adjusting member providing device 100 in Figure 1. Functionally, as shown in Figure 1, the retinal sensitivity adjusting member providing device 100 includes an acquisition unit 110, a storage unit 120, a transmission unit 130, and a display unit 140.

[0030] The acquisition unit 110 acquires effect information, light source information, and subject movement information input from an input device connected to the retinal sensitivity adjusting member providing device 100, such as a touch panel (see FIG. 10), and stores the information in the storage unit 120. The acquisition unit 110 also acquires the lens and recommended use information for the lens transmitted from the design device 200.

[0031] The transmitting unit 130 transmits the effect information, light source information, and subject movement information acquired by the acquiring unit 110 to the design device 200 .

[0032] The display unit 140 displays the lens acquired by the acquisition unit 110 and the recommended use information for the lens to the user, a doctor, or a store clerk at a store that sells the lens.

[0033] Next, a description will be given of each processing unit in the design device 200 in Fig. 1. Functionally, the design device 200 includes an acquisition unit 210, a storage unit 220, a determination unit 230, and a transmission unit 240, as shown in Fig. 1.

[0034] The acquisition unit 210 acquires the effect information, light source information, and subject movement information transmitted from the retinal sensitivity adjusting member providing device 100.

[0035] The storage unit 220 stores the effect information, light source information, and object mobility information acquired by the acquisition unit 210. The effect information, light source information, and object mobility information may be stored in the storage unit 120, or some or all of the information may be deleted or anonymized before being stored. The information may also be encrypted before being stored. The information stored in the storage unit 220 includes information that is temporarily stored. That is, the effect information, light source information, and object mobility information are temporarily stored, and the determination unit 230 determines a lens and recommended lens use information based on the information. After the determination, the effect information, light source information, and object mobility information used in the determination are deleted.

[0036] The storage unit 220 also stores a design information database. The design information database, not shown, is a database related to lens design information. Specifically, it contains information relating the difference and effect of the ratio of the relative stimulation amount of melanopsin and the luminous transmittance when a neutral density filter is used. For example, the relative stimulation amount of melanopsin and the luminous transmittance for each lens shown in FIG. 6 (described later) are associated with the difference between each lens and each light source shown in FIG. 8, and the effect of each lens, such as "wanting to sleep," are stored. Additionally, the design information database may also include lens materials, manufacturing methods, amounts of pigments, model names, and the like.

[0037] The determining unit 230 selects suitable design information from the lens design information database based on the effect information, light source information, and subject movement information, and then selects a lens corresponding to the selected design information.

[0038] When the determination unit 230 selects suitable design information from the design information database, it takes into consideration the degree of consideration of the influence of melanopsin cells based on information on the subject's mobility in the visual environment. Here, the degree of consideration is calculated by selecting, or weighting and averaging, the relative luminosity efficiency obtained by the cross-illumination method and the relative luminosity efficiency obtained by the direct comparison method based on the mobility information.

[0039] Here, the relative luminous efficiency adapted to the viewing environment will be described. 4A and 4B are conceptual diagrams showing the relative luminous efficiency using the alternating illumination method and the direct comparison method. Specifically, FIG. 4A shows the relationship between wavelength and relative luminous efficiency when the field of view changes rapidly, such as when driving a car. FIG. 4B shows the relationship between wavelength and relative luminous efficiency when the field of view changes slowly, such as when reading a book. The alternating illumination method involves alternately presenting a reference light and a test light at a high temporal frequency of about 25 Hz. The direct comparison method involves simultaneously presenting a reference light and a test light and directly comparing them.

[0040] As shown in Figure 4A, when the field of view is rapidly changing, the relative luminosity is well matched with the long-wavelength sensitive cones (L cones) and the middle-wavelength sensitive cones (M cones). This is thought to be because, under the cross-illumination method, only the L and M cones respond, and the short-wavelength sensitive cones (S cones) are unable to keep up with the stimulus and therefore do not contribute to brightness sensitivity.

[0041] Furthermore, as shown in FIG. 4B, it can be seen that the relative luminosity factor when the change in field of view is slow is well matched with L-, M-, and S-cones. This is thought to be because, in the direct comparison method, all of the L-, M-, and S-cone cone cells contribute to brightness sensitivity, resulting in higher sensitivity on the short wavelength side. It is also thought that melanopsin cells contribute in the direct comparison method. Based on the idea that melanopsin cells contribute, this embodiment takes into consideration the influence of melanopsin cells (the amount of stimulation to melanopsin cells) when selecting lenses from the design information database.

[0042] Conventionally, lens design has generally been carried out taking into account the relative luminous efficiency under the cross illumination method. Figure 5 shows specific examples of the relative luminous efficiency under the cross illumination method and the relative luminous efficiency under the direct comparison method. As can be seen, the relative luminous efficiency under the direct comparison method differs from that under the cross illumination method. For this reason, lenses are designed taking into account the fact that the relative luminous efficiency varies depending on the viewing environment.

[0043] That is, when the object movement information is "dynamic," an appropriate lens is selected based on the luminous transmittance derived from the relative luminous efficiency obtained by the cross illumination method. When the object movement information is "stationary," an appropriate lens is selected based on the luminous transmittance calculated from the relative luminous efficiency obtained by the direct comparison method. When the object movement information is both "dynamic" and "stationary," the relative luminous efficiency obtained by the cross illumination method and the relative luminous efficiency obtained by the direct comparison method may be weighted and averaged for calculation.

[0044] Furthermore, conventionally, luminous transmittance and spectral transmittance (lens color) have been used to evaluate lenses. In this embodiment, instead of spectral transmittance, the degree to which the photoreceptors in the retina are stimulated by illumination light is quantitatively calculated. Lenses are then designed using this amount of photoreceptor stimulation (amount of stimulation to melanopsin cells). In other words, by using the amount of stimulation to melanopsin cells instead of spectral transmittance (lens color), the amount of stimulation to melanopsin cells varies depending on the light source, even for the same lens, allowing appropriate lens selection depending on the viewing environment.

[0045] Figure 6 shows the relationship between melanopsin stimulation and luminous transmittance for seven types of functional lenses that cut specific wavelengths and 26 types of light-blocking lenses. The functional lenses are: 480cut+UV400 lenses (prepared by the method described in International Publication No. 2015 / 037627) that selectively cut ultraviolet rays and wavelengths around 480 nm; 460cut+UV400 lenses (prepared by the method described in International Publication No. 2020 / 218508) that selectively cut ultraviolet rays and wavelengths around 460 nm; 460cut+UV420 lenses (prepared by the method described in International Publication No. 2020 / 218508) that selectively cut wavelengths around 420 nm and 460 nm; and 460cut+UV420 lenses (prepared by the method described in International Publication No. 2020 / 218508) that selectively cut ultraviolet rays and wavelengths around 585 nm. There are seven types of lenses: 585cut + UV400 (prepared by the method described in JP 2013-061653 A), which selectively cuts wavelengths around 420nm, 420cut (prepared by the method described in Patent No. 6861819 A), 460cut (prepared by the method described in WO 2020 / 218508 A), which selectively cuts wavelengths around 585nm, and 585cut (prepared by the method described in JP 2013-061653 A). Examples of light-shielding lenses include EyeLife (light-shielding glasses) (manufactured by Tokai Optical Co., Ltd.) "CCP" and "CCP400", and can be selected appropriately.

[0046] The dotted line in Figure 6 indicates a luminous transmittance of 75%, and the solid line is the locus when the lens has the same characteristics as a neutral density filter (ND filter). Lenses below the solid line suppress stimulation to melanopsin cells more selectively than ND filters, while lenses above the solid line suppress stimulation to L and M cone cells more selectively than ND filters. Light-blocking lenses with low luminous transmittance are plotted below the solid line, indicating that they selectively suppress the amount of stimulation to melanopsin cells. On the other hand, even among functional lenses, 480cut+UV400 and 585cut+UV400 have similar luminous transmittances (480cut+UV400: 0.79925345, 585cut+UV400: 0.77313853), resulting in the same perceived brightness. However, the 480cut+UV400 lens exhibits low melanopsin stimulation, while the 585cut+UV400 lens exhibits high melanopsin stimulation. Melanopsin cells are known to significantly influence circadian rhythm regulation. Therefore, for example, if the effect information is "good awakening," the light source information is "sunlight," and the subject movement information is "still," while still achieving the same perceived brightness, the 585cut+UV400 lens would be selected to increase the stimulation to melanopsin cells. This is thought to reset the body clock. Furthermore, when the effect information is "want to sleep," the light source information is "LED," and the subject movement information is "still," a 480cut+UV400 lens is selected to reduce the amount of stimulation to melanopsin cells. This is thought to improve sleep quality. Furthermore, because the subject movement information is "still," it is desirable that the luminous transmittance of the selected lens be calculated using the relative luminous efficiency obtained by the direct comparison method, as described above. That is, a lens can be selected based on effect information, light source information, and subject movement information, taking into consideration the degree of consideration of the influence of melanopsin cells. In addition, when the effect information is "driving a car," the light source information is "sunlight," and the subject movement information is "dynamic," a lens with low luminous transmittance and a high relative stimulation level to melanopsin cells, such as "585 cut," is selected to reduce the luminous transmittance and increase the stimulation level to melanopsin cells. When the effect information is "driving a car," the light source information is "dark," and the subject movement information is "dynamic," a lens with high luminous transmittance and a high relative stimulation level to melanopsin cells, such as 420 cut, is selected to increase the stimulation level to melanopsin cells without reducing the luminous transmittance. Furthermore, because the subject movement information is "dynamic," it is desirable that the luminous transmittance of the selected lens be calculated using the relative luminous efficiency obtained by the cross-illumination method, as described above.

[0047] Furthermore, Figure 7 shows the luminous transmittance and stimulation level to melanopsin cells for the same lens under different light sources. The white dots in Figure 7 represent plot points for the LED light source, and the black dots represent plot points for the C light source. This shows that even with the same lens, the luminous transmittance and stimulation level to melanopsin cells can differ depending on the light source. This means, for example, that the perceived brightness (luminous transmittance) can increase or decrease when the same lens is used in a visual environment with a different light source.

[0048] Figure 8 shows the spectral radiance of the LED light source and the C light source. The LED light source has radiance peaks around 450 nm and 550 nm, and the C light source has less wavelength specificity than the LED light source.

[0049] Furthermore, to quantitatively investigate the influence of the light source, the difference between the two types of lenses was quantified using Euclidean distance on the luminous transmittance-relative stimulation to melanopsin cells plane. As shown in Figure 9, of the 33 lenses, the five types of lenses that were most influenced by the light source are surrounded by dashed-dot lines, and lenses that were least influenced by the light source are surrounded by dotted lines. Lenses that were less influenced by the light source are concentrated near the solid line, while lenses that were more influenced by the light source are distributed further from the solid line. The solid line is the locus when the lens has the same spectral transmittance characteristics as the ND filter, which shows that lenses that do not have wavelength-selective properties are less influenced by the light source, and conversely, lenses with high wavelength selectivity are more influenced by the type of light source.

[0050] When selecting suitable design information from the design information database, the determination unit 230 not only selects from the design information of lenses registered in the design information database, but also includes cases where it determines design information of lenses with performance not registered in the design information database. For example, it may determine design information of a lens with an intermediate amount of stimulation to melanopsin cells between the lenses registered in the design information database. In this case, the lens will be a custom-made lens rather than an existing lens.

[0051] The transmitting unit 240 transmits information about the lens selected by the determining unit 230 to the device 100 for providing a retinal sensitivity adjusting member.

[0052] Next, an example of an interface screen of the retinal sensitivity adjusting member providing device 100 will be described with reference to Figures 10 to 13. As shown in Figures 10 to 13, the interface of the terminal is an interface such as a touch panel that allows the user to input each item.

[0053] The interface screen shown in FIG. 10 displays a question asking for effect information related to the effect desired by the user, such as "What kind of effect do you want?", and displays selectable effect information stored in the storage unit 120. Here, the items marked with a "●" (black circle) on the drawing indicate that they have been selected. In this example, the effect information for "reading" has been selected. When any of the effect information is selected, the screen transitions to the interface screen shown in FIG. 11. Note that the effect information is not limited to the selection of effect information as shown in FIG. 10. A free-text entry field may be provided to accept free text input by the user, and keywords may be extracted from the accepted text to select effect information.

[0054] The interface screen shown in FIG. 11 displays a question asking for light source information of the visual environment that is affected to obtain the desired effect, "What kind of light source are you using?", and displays selectable light source information stored in the storage unit 120. Here, the items marked with a "●" (black circle) on the drawing indicate that they are selected. In this example, the "LED" light source information is selected. When any of the light source information is selected, the screen transitions to the interface screen shown in FIG. 12. Note that the light source information is not limited to the selection of light source information as shown in FIG. 11. A free text field may be provided to accept free text input by the user, and keywords may be extracted from the accepted text to select light source information.

[0055] The interface screen shown in FIG. 12 displays a question asking about object mobility information, such as "What do you use it for viewing?", and displays selectable object mobility information stored in the storage unit 120. Here, the item marked with a "●" (black circle) on the drawing indicates that it is selected. In this example, the display indicating that the object mobility information of "stationary objects" is "stationary" is selected. When any of the object mobility information is selected, the screen transitions to the interface screen shown in FIG. 13. Note that the object mobility information is not limited to the selection of object mobility information as shown in FIG. 12. A free text field may be provided to accept free text input by the user, and keywords may be extracted from the accepted text to select object mobility information.

[0056] 13, the lens selected by the determination unit 230 is displayed as "The following lens is recommended," etc. Furthermore, recommended use information is displayed as "This lens can also be used in the following situations."

[0057] Furthermore, the display of questions is not limited to the interface screens shown in FIGS. 10 to 12, and all of the questions may be displayed simultaneously, for example.

[0058] 14 is a diagram showing an example of a processing routine executed by the retinal sensitivity adjusting member providing system 10. The operation of the retinal sensitivity adjusting member providing system 10 will be described with reference to FIG.

[0059] In step S100, a question about effect information is displayed on the interface screen of the device 100 for providing a retinal sensitivity adjusting member (see FIG. 10), and the process then proceeds to the next step, S102.

[0060] In step S102, the acquisition unit 110 determines whether or not an answer to the question about the effect information displayed in step S100 has been acquired. If it is determined that an answer to the question about the effect information has not been acquired, the process returns to step S102 again. On the other hand, if it is determined that an answer to the question about the effect information has been acquired, the process proceeds to the next step S104.

[0061] In step S104, a question about light source information is displayed on the interface screen of the device 100 for providing retinal sensitivity adjusting members (see FIG. 11), and the process then proceeds to the next step, S106.

[0062] In step S106, the acquisition unit 110 determines whether or not an answer to the question about the light source information displayed in step S104 has been acquired. If it is determined that an answer to the question about the light source information has not been acquired, the process returns to step S104 again. On the other hand, if it is determined that an answer to the question about the light source information has been acquired, the process proceeds to the next step S108.

[0063] In step S108, a question about subject movement information is displayed on the interface screen of the device 100 for providing retinal sensitivity adjusting members (see FIG. 12), and the process then proceeds to the next step, S110.

[0064] In step S110, the acquisition unit 110 determines whether or not an answer to the question about the target object mobility information displayed in step S108 has been acquired. If it is determined that an answer to the question about the target object mobility information has not been acquired, the process returns to step S108 again. On the other hand, if it is determined that an answer to the question about the target object mobility information has been acquired, the process proceeds to the next step S112.

[0065] In step S112, the lens and recommended use information are determined by the determination unit 230. Then, the process proceeds to the next step, S114.

[0066] In step S114, the lens determined in step S112 and the recommended use information are displayed on the interface screen of the device 100 for providing retinal sensitivity adjusting members (see FIG. 13), and the process then ends.

[0067] As described above, according to this embodiment, it is possible to provide a lens appropriate for achieving the effect desired by the user, and to present recommended usage information for the lens to the user.

[0068] The present disclosure is not limited to the above-described embodiment, and various modifications and applications are possible without departing from the gist of the present disclosure.

[0069] For example, although the present specification has described an embodiment in which a program is pre-installed, the program may be provided by being stored on a computer-readable recording medium.

[0070] Furthermore, a doctor or a salesperson at a store selling lenses may perform the processing performed by the retinal sensitivity adjusting member providing device 100 and the design device 200. Specifically, the doctor or salesperson may acquire effect information, light source information, and subject movement information from the user, and determine lenses and recommended use information based on the acquired information.

[0071] The disclosure of Japanese Patent Application No. 2021-191602, filed on November 25, 2021, is incorporated herein by reference in its entirety.

[0072] All publications, patent applications, and technical standards mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent application, or technical standard was specifically and individually indicated to be incorporated by reference.
