[0025] The present embodiment will be described in detail below. The headache cause determination device 200 of this embodiment determines and outputs the cause of a headache based on the input answer information. Note that the user of this embodiment is, for example, a customer who has a migraine symptom and is about to purchase lenses at a store that sells glasses.

[0026] <System Configuration According to the First Embodiment>

[0027] Fig. 1 is a block diagram showing an example of the system configuration of a headache cause determination system 10 according to the first embodiment. As shown in Fig. 1, in the headache cause determination system 10, a plurality of terminals and a headache cause determination device 200 are connected via a network N.

[0028] The terminal 100 shown in FIG. 1 is a device such as a smartphone terminal owned by a user or a tablet terminal assigned to a store that sells glasses. The terminal 100 has an interface as shown in FIGS. 4A to 4H described later. The interface displays question information related to the user's migraine symptoms, inputs answer information to the question information, and inputs user information including information on the user's place of residence. The interface also displays information about ophthalmic lenses received from the headache cause determination device 200 and retailer information about a store that sells the ophthalmic lenses. The terminal 100 transmits answer information and user information together with identification information assigned to the terminal 100 to the headache cause determination device 200. The identification information is identification information of the terminal 100 and identification information of the user who has acquired the information.

[0029] The headache cause determination device 200 configured as shown in Figure 1 can be configured by a computer including a CPU, a RAM, and a ROM that stores programs for executing each processing routine described below and various data.

[0030] For example, the headache cause determination device 200 can be realized by a computer 250 shown in Fig. 2. The computer 250 includes a CPU 251, a memory 252 as a temporary storage area, and a non-volatile storage unit 220. The computer 250 also includes an input / output interface (I / F) 254 to which an input / output device or the like (not shown) is connected, and a read / write (R / W) unit 255 that controls reading and writing of data from and to a recording medium. The computer 250 also includes a network I / F 256 that is connected to a network such as the Internet. The CPU 251, the memory 252, the storage unit 220, the input / output I / F 254, the R / W unit 255, and the network I / F 256 are connected to one another via a bus 257.

[0031] The storage unit 220 can be realized by a hard disk drive (HDD), a solid state drive (SSD), a flash memory, etc. The storage unit 220 as a storage medium stores data that can determine whether or not the cause of the user's migraine symptoms may be light-based, and a program for causing the computer 250 to function. The CPU 251 reads the program from the storage unit 220, expands it in the memory 252, and sequentially executes the processes contained in the program.

[0032] The above is a description of an example of the electrical configuration of the computer in FIG.

[0033] Here, the storage unit 220 stores question information, answer information, data, user information of the user, lens information, and retailer information. The question information is information about the user's migraine symptoms. The answer information is information to the question information input by the user. The data is a program that can determine whether or not the cause of the user's migraine symptoms may be light-based. The lens information is information about ophthalmic lenses that are recommended for use in preventing or reducing migraine symptoms. The retailer information is information about stores that sell ophthalmic lenses that are recommended for use in preventing or reducing the user's migraine symptoms.

[0034] After the determination unit 230, which will be described later, determines whether or not the cause of the user's migraine symptoms is likely to be light-based, all of the answer information and user information may be stored in the storage unit 220. Alternatively, part of the answer information and part of the user information may be stored, and the other answer information and user information may be deleted or anonymized before being stored. The answer information and user 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 answer information and user information input by the user are temporarily stored, and the determination unit 230 determines whether or not the cause of the user's migraine symptoms is possibly due to light based on the information. After the determination by the determination unit 230, the answer information and user information used in the determination are deleted.

[0035] The question information regarding the user's migraine symptoms will be described with reference to FIG. The question information includes questions about the state in which the user's migraine symptoms are occurring, questions about the cause of the user's migraine symptoms, and questions about the state before and after the user's migraine symptoms occur.

[0036] The questions regarding the user's migraine condition are primarily questions about whether, when the user has a migraine, light can make the migraine symptoms worse, or whether the user finds light dazzling or uncomfortable. For example, among the questions shown in Figure 3, question 1, "When you have a migraine, does light ever make your migraine symptoms worse?" and "When you have a migraine, does light ever feel dazzling or uncomfortable?" are relevant.

[0037] The questions regarding the user's migraine condition further include a question regarding whether light can cause pain in or around the eye when the user has a migraine. For example, among the question information shown in FIG. 3, the question 3 "When you have a migraine, does light ever cause pain in or around your eyes?" corresponds to this question.

[0038] The question regarding the cause of the user's migraine symptoms is primarily a question regarding whether light can cause migraine symptoms. For example, among the question information shown in FIG. 3, question 4, "Can light cause migraine symptoms?", corresponds to this question.

[0039] The questions regarding the user's condition before and after the onset of a migraine episode further include a question regarding whether the user experiences light sensitivity between the time when a migraine episode subsides and the onset of the next migraine episode. For example, among the question information shown in FIG. 3, question 5, "Do you ever become sensitive to light before you get a migraine?", corresponds to this question.

[0040] The question information is not limited to that shown in FIG. 3, but other question information may be used, and it is not necessary to provide all of the information shown in FIG.

[0041] As shown in FIG. 3, as the answer information to the question information input by the user, information of "yes" or "no" is stored as the answer to question 1. Furthermore, information of "yes" or "no" is stored as the answer to question 2. Furthermore, information of "yes" or "no" is stored as the answer to question 3. Furthermore, information of "yes" or "no" is stored as the answer to question 4. Furthermore, information of "yes" or "no" is stored as the answer to question 5. Here, in FIG. 3, "○ (circle)" is entered in the column of the selected answer of "yes" or "no", and the columns other than the selected answer are left blank. For example, in this example, it is stored that "yes" was selected only for question 1, and "no" was selected for the other questions 2 to 5. In addition, the answer information in FIG. 3 that has a circle (○) indicates that it has been selected by the user.

[0042] Examples of data that can determine whether the cause of a user's migraine symptoms may be light-related include a program that determines that the cause of a user's migraine symptoms may be light-related if any of the answer information to the questions shown in Figure 3 is "yes," as will be described later.

[0043] Although not shown, the user information includes, for example, information regarding the user's place of residence, information regarding age, information regarding sex, information regarding occupation, information regarding living environment, and the like. The user information is not limited to the above, but may include other information, such as a doctor's prescription.

[0044] Also, a customer database may be provided that records the history of user information. Response information is also recorded in the customer database.

[0045] Examples of lens information regarding eye lenses that are recommended for use in preventing or reducing migraine symptoms include information regarding eye lenses that selectively block light at around 480 nm, although this information is not shown in the figure.

[0046] Here, eye lenses that selectively block light at around 480 nm have been shown to be effective against photosensitive migraines. The mammalian retina contains three types of cones, S, M, and L cones, rods, and a newly discovered photoreceptor called intrinsically photosensitive retinal ganglion cells (ipRGCs), which have peak sensitivities to light with wavelengths of 420 nm (S cones), 530 nm (M cones), 560 nm (L cones), 500 nm (rods), and 480 nm (ipRGCs), respectively. For example, since ipRGCs respond strongly to blue component light with a wavelength of around 480 nm, it is believed that by using eyewear such as glasses or sunglasses that have an optical material with low transmittance of blue component light in the wavelength range (2) above, such as the optical material disclosed herein, the user can prevent and alleviate photosensitive migraines and eyestrain, etc.

[0047] In addition, the lens information stored in the memory unit 220 may include eye lenses that are recommended for use to prevent or reduce migraine symptoms, as well as eye lenses that selectively cut light around 460 nm for digital device users and eye lenses that cut other wavelengths.

[0048] Store information regarding a store that sells eye lenses that are recommended for use to prevent or reduce the user's migraine symptoms includes the store's name, address, and contact information (telephone number, email address, etc.), although not shown.

[0049] Below, we will explain each processing unit in the headache cause determination device 200 in Fig. 1. Functionally, the headache cause determination device 200 includes a collection unit 210, a storage unit 220, a determination unit 230, and a transmission unit 240, as shown in Fig. 1.

[0050] The collecting unit 210 acquires the answer information and the user information input from the terminal. In addition, the collecting unit 210 may read the GPS (Global Positioning System) information of the terminal even if the information on the user's place of residence among the user information is not input or is input.

[0051] The determination unit 230 determines whether or not the cause of the user's migraine symptoms is likely to be light-related based on the user's response information to the question information and the data stored in the memory unit 220, and outputs the result. Specifically, when the determination unit 230 determines that the cause of the user's migraine symptoms may be light-based, it outputs the determination result. Then, from the lens information stored in the storage unit 220, it determines an ophthalmic lens that selectively blocks light around 480 nm as an ophthalmic lens recommended for use in preventing or reducing the user's migraine symptoms, and outputs the result to the terminal by the transmission unit 240.

[0052] Furthermore, when determining and outputting the ophthalmic lenses recommended for use in preventing or reducing the user's migraine symptoms, the determination unit 230 determines candidate stores that sell the ophthalmic lenses recommended for use in preventing or reducing the user's migraine symptoms based on information about the user's place of residence and the retailer information stored in the storage unit 220. Then, the determination result is output to the terminal 100 by the transmission unit 240. It is preferable that the determined candidates are stores located near the user's place of residence or workplace.

[0053] Here, the determination as to whether or not the cause of the user's migraine symptoms may be light-related is made if any of the answer information for each question information shown in Figure 3 is "yes," so that it is determined that the cause of the user's migraine symptoms may be light-related.

[0054] In addition, the determination of whether the cause of the user's migraine symptoms may be light-based is not limited to the case where it is determined that the cause of the user's migraine symptoms may be light-based when at least one of the answer information of the question information shown in FIG. 3 is "yes", and a weighting may be set for each question. For example, questions 1 to 3 may be determined to be light-based when at least one of the answer information is "yes", and questions 4 and 5 may be determined to be light-based when both the answer information are "yes". Also, even if the answer information of any of questions 1 to 3 is "yes", it may be determined that the cause of the user's migraine symptoms may be light-based only when the answer information of question 4 or question 5 is "yes".

[0055] The transmission unit 240 transmits information about the ophthalmic lens and information about candidate stores that sell the ophthalmic lens as a result of the determination made by the determination unit 230 regarding the identification information to the terminal 100 to which the identification information has been assigned. The transmitted information about the ophthalmic lens and information about candidate stores that sell the ophthalmic lens are displayed on the interface of the terminal 100. Here, it is preferable that the displayed store candidates are displayed in order of proximity to the user's place of residence, for example.

[0056] Next, an example of a screen of the interface of the terminal will be described with reference to Figures 4A to 4H. As shown in Figures 4A to 4H, the interface of the terminal is an interface such as a touch panel that allows the user to input each item.

[0057] In the interface screen shown in Fig. 4A, the user can select either an affirmative "Yes" or a negative "No" in response to the question "Do you have migraines?" If the user selects "No", a screen is displayed that recommends eye lenses that selectively block light around 460 nm based on lens information, depending on whether the user uses a personal computer or other factors based on the user information. On the other hand, if "Yes" is selected as shown in Fig. 4A, the screen transitions to the interface screen in Fig. 4B. Here, the selected item is shown in white text on the drawing.

[0058] In the interface screen shown in Fig. 4B, question 1 of the question information is displayed as "When you have migraine symptoms, does light sometimes worsen your migraine symptoms?", and the user selects either "Yes" which is affirmative or "No" which is negative. At this time, the answer information is stored in the storage unit 220. In this example, a case where "No" is selected by the user will be described, but even if "Yes" is selected, the interface screen transitions to that of Fig. 4C, just as in the case where "No" is selected.

[0059] In the interface screen shown in FIG. 4C, question 2 of the question information is displayed as "Does light cause pain in or around the eye when you have a migraine?", and the user selects either "Yes" which is affirmative or "No" which is negative. At this time, the answer information is stored in the storage unit 220. In this example, the case where the user selects "Yes" will be described. Then, the screen transitions to the next interface screen in FIG. 4D.

[0060] In the interface screen shown in Fig. 4D, question 3 of the question information is displayed as "Do you ever feel that light is dazzling or uncomfortable when you have migraine symptoms?", and the user selects either "Yes" which is affirmative or "No" which is negative. At this time, the answer information is stored in the storage unit 220. In this example, the case where the user selects "Yes" will be described. Then, the screen transitions to the next interface screen in Fig. 4E.

[0061] In the interface screen shown in FIG. 4E, question 4 of the question information is displayed as "Does light ever cause migraine symptoms?", and the user selects either "Yes" which is affirmative or "No" which is negative. At this time, the answer information is stored in the storage unit 220. In this example, the case where the user selects "Yes" will be described. Then, the screen transitions to the next interface screen in FIG. 4F.

[0062] In the interface screen shown in FIG. 4F, question 5 of the question information is displayed as "Do you ever become sensitive to light before a migraine headache occurs?", and the user selects either "Yes" which is affirmative or "No" which is negative. At this time, the answer information is stored in the storage unit 220. In this example, a case where the user selects "No" will be described. Then, the screen transitions to the next interface screen in FIG. 4G.

[0063] The interface screen shown in FIG. 4G displays the result determined by the determination unit 230, such as "We recommend lenses for photosensitive migraine sufferers," along with a list of candidate stores that sell eye lenses that are recommended for use to prevent or reduce the user's migraine symptoms, based on information about the user's place of residence.

[0064] Moreover, if the answer information for all of questions 1 to 5 is negative, that is, "No," the interface screen transitions from the interface screen shown in FIG. 4F to the interface screen shown in FIG. 4H, not the interface screen shown in FIG. 4G. The interface screen shown in Figure 4H displays a message such as "We recommend blue light blocking lenses," recommending eye lenses that selectively block light around 460 nm for digital device users, along with a list of potential stores that sell the eye lenses based on information about the user's place of residence.

[0065] Here, as described above, the determination of whether or not the cause of the user's migraine symptoms may be light-based is made in such a way that if any one of the answer information for the question information shown in the figure is affirmative, "Yes," it is determined that the cause of the user's migraine symptoms may be light-based. Therefore, if "Yes" is selected in the middle of answering questions 1 to 5, the display of the questions may be terminated at that stage, and the screen may transition to the interface screen of FIG. 4G.

[0066] Furthermore, the display of the questions is not limited to the interface screens shown in FIGS. 4B to 4F, and for example, questions 1 to 5 may be displayed simultaneously.

[0067] <Operation of the First Embodiment>

[0068] 5 is a diagram showing an example of a processing routine executed by the headache cause determination device 200. The operation of the headache cause determination device 200 will be described with reference to FIG.

[0069] In step S100, the collection unit 210 collects user information input via the interface screen of the terminal 100. After acquiring the user information, the process proceeds to the next step S102.

[0070] In step S102, a question as to whether or not the user has a migraine symptom is displayed on the interface screen of the terminal 100 (see FIG. 4A), and the process then proceeds to the next step S104.

[0071] In step S104, the collection unit 210 collects answers to the questions displayed in step S102 described above, and determines whether the answer information is "yes", i.e., whether the user has migraine symptoms. If the user has migraine symptoms, the process proceeds to the next step S106.

[0072] In step S106, the five questions are displayed on the interface screen of the terminal 100 (see Figs. 4B, 4C, 4D, 4E, and 4F), and the process proceeds to the next step S108.

[0073] In step S108, it is determined whether or not all five questions have been answered. If it is determined that all five questions have been answered, the process proceeds to the next step S110, and if it is not determined that all five questions have been answered, the process continues with step S106.

[0074] In step S110, the collection unit 210 collects answer information to the question information displayed in step S106, and determines whether or not any of the answer information includes an answer of "Yes." If any of the answer information includes an answer of "Yes," the process proceeds to the next step S112.

[0075] In step S112, the result of recommending ophthalmic lenses for patients with photosensitive migraine and candidate stores that sell the ophthalmic lenses based on the user information are displayed (see FIG. 4G). Then, the process ends.

[0076] On the other hand, if it is determined in step S104 that the user is not a user with migraine symptoms, the process proceeds to step S114, where a result of recommending ophthalmic lenses other than ophthalmic lenses for photosensitive migraine patients based on the user information and candidate stores selling the ophthalmic lenses are displayed (see FIG. 4H). Also, if it is determined in step S110 that there is not even one answer of "Yes", the process similarly proceeds to step S114, where a result of recommending ophthalmic lenses other than ophthalmic lenses for photosensitive migraine patients and candidate stores selling the ophthalmic lenses are displayed (see FIG. 4H). Then, the process ends.

[0077] As described above, the headache cause determination system 10 according to the first embodiment can determine whether the cause of the user's migraine symptoms is light, taking into account the answers to a number of questions. Then, it can present ophthalmic lenses recommended for the user and stores that sell the ophthalmic lenses.

[0078] <System Configuration According to the Second Embodiment>

[0079] The second embodiment will be described with reference to Figs. 6A and 6B. In the first embodiment described above, if "Yes" is selected for any one of questions 1 to 5, it is determined that the cause of the user's migraine symptoms may be light-based, and ophthalmic lenses recommended for use in preventing or reducing the user's migraine symptoms are determined. In the second embodiment, instead of selecting "Yes" or "No" for answering information to question information, the level of agreement of subjective symptoms with the question is converted into points, and if the points exceed a predetermined threshold, it is determined that the cause of the user's migraine symptoms may be light-based, and ophthalmic lenses recommended for use in preventing or reducing the user's migraine symptoms are determined.

[0080] The following description will focus on the differences from the first embodiment described above, and descriptions of overlapping parts will be simplified or omitted.

[0081] FIG. 6A is a diagram showing question information and answer information. Specifically, when the question information is question 1 "Does light worsen migraine symptoms when you have migraine symptoms?", "Level 1" to "Level 5" are displayed on the interface screen as answer candidates instead of "Yes" or "No", and the user selects one of "Level 1" to "Level 5" based on the subjective symptoms. For example, "Level 5" is set to "4 points", "Level 4" is set to "3 points", "Level 3" is set to "2 points", "Level 2" is set to "1 point", and "Level 1" is set to "0 points". In this example, it is assumed that "Level 5" is selected. Therefore, "4 points" is stored in the storage unit 220 as answer information (see FIG. 6B). In addition, the answer information in FIG. 6A that has a circle (○) therein indicates that the answer has been selected by the user.

[0082] In addition, in the case of question 2 "Do you ever feel that light is dazzling or uncomfortable when you have migraine symptoms?", "Level 1" to "Level 5" are displayed on the interface screen as answer candidates, and the user selects one of "Level 1" to "Level 5" based on his / her subjective symptoms. For example, "Level 5" is set to "4 points", "Level 4" to "3 points", "Level 3" to "2 points", "Level 2" to "1 point", and "Level 1" to "0 points". In this example, it is assumed that "Level 1" has been selected. Therefore, "0 points" is stored in the storage unit 220 as answer information (see FIG. 6B).

[0083] In addition, in the case of question 3 "Does light ever cause pain in or around the eye when you have migraine symptoms?", "Level 1" to "Level 5" are displayed on the interface screen as answer candidates, and the user selects one of "Level 1" to "Level 5" based on his / her subjective symptoms. For example, "Level 5" is set to "4 points", "Level 4" to "3 points", "Level 3" to "2 points", "Level 2" to "1 point", and "Level 1" to "0 points". In this example, it is assumed that "Level 2" is selected. Therefore, "1 point" is stored in the storage unit 220 as answer information (see FIG. 6B).

[0084] Furthermore, in the case of question 4 "Does light ever cause migraine symptoms?", "Level 1" to "Level 5" are displayed on the interface screen as answer candidates, and the user selects one of "Level 1" to "Level 5" based on his / her subjective symptoms. For example, "Level 5" is set to "4 points", "Level 4" to "3 points", "Level 3" to "2 points", "Level 2" to "1 point", and "Level 1" to "0 points". In this example, it is assumed that "Level 4" has been selected. Therefore, "3 points" is stored in the storage unit 220 as answer information (see FIG. 6B).

[0085] In addition, in the case of question 5 "Do you ever become sensitive to light before the onset of a migraine headache?", "Level 1" to "Level 5" are displayed on the interface screen as answer candidates, and the user selects one of "Level 1" to "Level 5" based on his / her subjective symptoms. For example, "Level 5" is set to "4 points", "Level 4" to "3 points", "Level 3" to "2 points", "Level 2" to "1 point", and "Level 1" to "0 points". In this example, it is assumed that "Level 4" has been selected. Therefore, "3 points" is stored in the storage unit 220 as answer information (see FIG. 6B).

[0086] The determination unit 230 counts the points of the answer information stored in the storage unit 220 and calculates the total points. In this example, the total points are "11" points, as shown in FIG. 6B. Then, it is determined whether or not the total points is equal to or greater than a predetermined threshold, for example, "10 points." Since the total points are equal to or greater than "10 points" in this example, it is determined that the cause of the user's migraine symptoms may be light-based, and an ophthalmic lens that is recommended for use in preventing or reducing the user's migraine symptoms is determined.

[0087] Although the levels and points are set to the same for all of Questions 1 to 5, this is not limited to the above. For Questions 1 to 3, the point allocation may be set higher than that for Questions 4 and 5, for example, "Level 5" is "10 points" and "Level 4" is "9 points."

[0088] In addition, the predetermined threshold is not limited to "10 points" and may be other points, and the predetermined threshold may be increased or decreased according to user information. This is because it is known that women in their 20s to 40s are particularly prone to migraine symptoms, and for such users, the predetermined threshold may be set to a lower point than for other users.

[0089] In addition, the determination unit 230 is not limited to the case where it counts points based on the answer information and determines that the cause of the user's migraine symptoms may be light-based. For example, the answer information may be input to a trained model trained using the weight of the answer information and correct answer data of other users in the past as training data, and it may be determined that the cause of the user's migraine symptoms may be light-based.

[0090] As described above, the headache cause determination system 10 according to the second embodiment can determine whether the cause of the user's migraine symptoms is light, taking into account the answers to a number of questions. Then, it can present ophthalmic lenses recommended for the user and stores that sell the ophthalmic lenses.

[0091] <System configuration according to the third embodiment>

[0092] The third embodiment will be described with reference to Figs. 7A and 7B. In the first embodiment described above, if "Yes" is selected for any one of questions 1 to 5, it is determined that the cause of the user's migraine symptoms may be light-based, and an ophthalmic lens recommended for use in preventing or reducing the user's migraine symptoms is determined. In the third embodiment, instead of selecting "Yes" or "No" as answer information to the question information, the frequency of subjective symptoms to the question is selected, which is converted into points, and if the points exceed a predetermined threshold, it is determined that the cause of the user's migraine symptoms may be light-based, and an ophthalmic lens recommended for use in preventing or reducing the user's migraine symptoms is determined.

[0093] The following description will focus on the differences from the first embodiment described above, and descriptions of overlapping parts will be simplified or omitted.

[0094] FIG. 7A is a diagram showing question information and answer information. Specifically, when the question information is question 1 "Does light worsen migraine symptoms when you have migraine symptoms?", instead of "yes" or "no", answer candidates are displayed on the interface screen as "often", "sometimes", "occasionally", "almost never", and "none", and the user selects one of "often", "sometimes", "almost never", and "none" based on the subjective symptoms. For example, "four points" is set for "often", "three points" for "sometimes", "two points" for "almost never", "one point" for "almost never", and "zero point" for "level 1". In this example, it is assumed that "almost never" is selected. Therefore, "one point" is stored in the storage unit 220 as answer information (see FIG. 7B). In addition, the answer information in FIG. 7A that has a circle (○) therein indicates that the answer has been selected by the user.

[0095] In addition, in the case of question 2 "Do you feel light is dazzling or uncomfortable when you have migraine symptoms?", answer candidates "often", "sometimes", "occasionally", "almost never", and "none" are displayed on the interface screen, and the user selects one of "often", "sometimes", "occasionally", "almost never", and "none" based on the subjective symptoms. For example, "four points" is set for "often", "three points" for "sometimes", "two points" for "almost never", "one point" for "almost never", and "zero points" for "level 1". In this example, it is assumed that "none" is selected. Therefore, "0 points" is stored in the storage unit 220 as answer information (see FIG. 7B).

[0096] In addition, in the case of question 3 "Does light cause pain in or around the eye when you have migraine symptoms?", answer candidates "often", "sometimes", "occasionally", "almost never", and "never" are displayed on the interface screen, and the user selects one of "often", "sometimes", "almost never", and "never" based on the subjective symptoms. For example, "often" is set to "4 points", "sometimes" to "3 points", "almost never" to "almost never", and "level 1" to "0 points". In this example, it is assumed that "almost never" is selected. Therefore, "1 point" is stored in the storage unit 220 as answer information (see FIG. 7B).

[0097] In addition, in the case of question 4 "Does light ever cause migraine symptoms?", answer candidates "often", "sometimes", "occasionally", "hardly", and "never" are displayed on the interface screen, and the user selects one of "often", "sometimes", "occasionally", "hardly", and "never" based on the subjective symptoms. For example, "often" is set to "4 points", "sometimes" is set to "3 points", "sometimes" is set to "2 points", "hardly" is set to "1 point", and "level 1" is set to "0 points". In this example, it is assumed that "sometimes" is selected. Therefore, "3 points" is stored in the storage unit 220 as answer information (see FIG. 7B).

[0098] In addition, in the case of question 5 "Do you ever become sensitive to light before a migraine occurs?", answer candidates "often", "sometimes", "occasionally", "almost never", and "never" are displayed on the interface screen, and the user selects one of "often", "sometimes", "occasionally", "almost never", and "never" based on the subjective symptoms. For example, "four points" is set for "often", "three points" for "sometimes", "two points" for "almost never", "one point" for "almost never", and "zero point" for "level 1". In this example, it is assumed that "sometimes" is selected. Therefore, "three points" is stored in the storage unit 220 as answer information (see FIG. 7B).

[0099] The determination unit 230 counts the points of the answer information stored in the storage unit 220 and calculates the total points. In this example, as shown in FIG. 7B, the total points are "8". Then, it is determined whether or not the total points is equal to or greater than a predetermined threshold, for example, "10 points". In this example, since the total points are not equal to or greater than "10 points", it is not determined that the cause of the user's migraine symptoms may be light-based. Therefore, it is determined to recommend eye lenses that selectively cut light around 460 nm for digital device users, rather than eye lenses that are recommended for use in preventing or reducing the user's migraine symptoms.

[0100] In addition, the frequency of subjective symptoms and points are set to be the same for all of questions 1 to 5, but this is not limited to this. For questions 1 to 3, the points may be set higher than those for questions 4 and 5, for example, "often" is assigned "10 points" and "sometimes" is assigned "9 points."

[0101] In addition, the predetermined threshold is not limited to "10 points" and may be other points, and the predetermined threshold may be increased or decreased according to user information. This is because it is known that women in their 20s to 40s are particularly prone to migraine symptoms, and for such users, the predetermined threshold may be set to a lower point than for other users.

[0102] In addition, the determination unit 230 is not limited to the case where it counts points based on the answer information and determines that the cause of the user's migraine symptoms may be light-based. For example, the answer information may be input to a trained model trained using the weight of the answer information and correct answer data of other users in the past as training data, and it may be determined that the cause of the user's migraine symptoms may be light-based.

[0103] As described above, the headache cause determination system 10 according to the third embodiment can determine whether the cause of the user's migraine symptoms is light, taking into account the answers to a number of questions. Then, it can present ophthalmic lenses recommended for the user and stores that sell the ophthalmic lenses.
