Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to a vision detection method, a vision detection device, an electronic device, a computer-readable storage medium, and a computer program product. Background Art

[0002] Visual acuity, also known as visual acuity, reflects the ability of the macula of the retina to identify spatial details. When the eyes are naturally relaxed, emmetropes can clearly identify visual targets 5 meters away from the eye chart, while for those with refractive errors, it is blurry. Vision test is one of the important items in routine ophthalmological examinations. Usually, the examinee is required to look at the visual target 5 meters away. The test result at this time reflects the examinee's far vision level. The early symptoms of myopia in children are often manifested as a significant decrease in far vision level.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0043] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The words "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0044] Generally, myopia is mainly divided into school myopia and pathological myopia. School myopia accounts for the vast majority of myopia. As the name suggests, myopia originates, often occurs in schools and shows a trend of continuous progression, so schools are the key targets for myopia prevention and control. "Far" vision is closely related to the degree of myopia. Monitoring "far" vision at any time is crucial for myopia prevention and control. Accurately, quickly and timely testing of students' "far" vision is an effective and economical method to monitor the occurrence and progression of students' myopia.

[0045] At present, the vision screening modes for adolescents are mainly based on two methods: "students go to the hospital" and "doctors go to campus". However, both modes require the participation of ophthalmic professionals, and the manpower and material resources required to organize vision screening activities are relatively large. There is a lack of convenient, accurate and easy-to-implement means of self-examination of vision within the campus. Although some vision testing processes have certain conveniences, there are still problems such as the vision test procedures are not rigorous enough, the sight mark design is not scientific enough, the vision test distance is too close, and it is difficult to ensure that the eyes are completely relaxed when the test is performed, so that the distance vision of the subject cannot be truly reflected. Due to the shortage of professional inspectors, the scarcity of inspection equipment, and the need to improve vision testing methods, the frequency of vision testing is low and the vision testing effect is poor. Therefore, the current situation of vision testing needs to be improved urgently.

[0046] At least one embodiment of the present disclosure provides a vision detection method, including: determining an initial position identifier in a first vision chart corresponding to an estimated vision, wherein the first vision chart includes multiple vision mark rows, each vision mark row includes multiple vision marks and a position identifier; feeding back multiple initial recognition results of the multiple vision marks corresponding to the initial position identifier; based on the multiple initial recognition results, determining a first specific vision mark row and a second specific vision mark row, wherein the first specific vision mark row is adjacent to the second specific vision mark row, the vision result corresponding to the second specific vision mark row is better than the vision result corresponding to the first specific vision mark row, the recognition results of multiple vision marks in the first specific vision mark row are all correct, and the recognition result of at least one vision mark in the second specific vision mark row is incorrect; and obtaining a vision detection result according to the vision result corresponding to the first specific vision mark row and the number of vision marks with correct recognition results in the second specific vision mark row.

[0047] The vision detection method provided by the embodiments of the present disclosure is based on the initial position marker corresponding to the estimated vision of the subject to obtain multiple initial recognition results, thereby determining the first specific visual mark row and the second specific visual mark row, and then obtaining the vision detection result. The vision detection method is simple and easy, and can save a lot of manpower and material resources, and can effectively ensure the timeliness and accuracy of vision monitoring.

[0048] For example, the vision detection method provided by the embodiments of the present disclosure can be applied to campuses and highlights the "smartness", that is, the vision detection method can timely monitor the probability and progression of myopia in students, and the vision detection method can reasonably and scientifically perform "distant" vision detection (for example, through a computer program), making the vision detection intelligent and controlled by the program throughout the process. When students perform vision detection, human-computer responses are performed without the need for professional detection personnel. The detection process is scientific and reasonable, and the detection steps are neither missing nor redundant, and the vision can be accurately measured. Of course, the vision detection method provided by the embodiments of the present disclosure can also be applied to other scenarios, without limitation.

[0049] The vision detection method, device, electronic device, medium and computer program product provided by the embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0050] Figure 1 A schematic flow chart of a vision detection method provided for at least one embodiment of the present disclosure; Figure 2 A schematic diagram of the partial structure of a first vision chart provided for at least one embodiment of the present disclosure.

[0051] like Figure 1 As shown, the vision detection method includes steps S100 to S400.

[0052] Step S100: determining an initial position mark in a first vision chart corresponding to the estimated vision, the first vision chart comprising a plurality of vision mark rows, each vision mark row comprising a plurality of vision marks and a position mark.

[0053] Step S200: Feedback a plurality of initial recognition results of a plurality of visual marks corresponding to the initial position marker.

[0054] Step S300: Based on multiple initial recognition results, determine a first specific sight mark row and a second specific sight mark row, the first specific sight mark row is adjacent to the second specific sight mark row, the vision result corresponding to the second specific sight mark row is better than the vision result corresponding to the first specific sight mark row, the recognition results of multiple sight marks in the first specific sight mark row are all correct, and the recognition result of at least one sight mark in the second specific sight mark row is incorrect.

[0055] Step S400: Obtain vision test results according to the vision results corresponding to the first specific sight mark row and the number of sight marks with correct identification results in the second specific sight mark row.

[0056] like Figure 2 As shown, for step S100, the first vision chart includes a plurality of sight mark rows 10, and each sight mark row 10 includes a plurality of sight marks 101 and a position mark 102. For example, the first vision chart is displayed by a display device, and there is a set distance between the subject and the first vision chart, such as a distance of at least 5 meters. The subject first independently determines the smallest row of sight marks in the first vision chart that can be seen clearly, and the position mark 102 in the sight mark row 10 is used as the initial position mark. The visual acuity corresponding to the sight mark row 10 where the initial position mark is located is the estimated visual acuity of the subject. For example, the position mark corresponding to the smallest row of sight marks that the subject believes can be seen clearly is 10, but it is not limited to this. For example, the subject can feedback the initial position mark through the first interactive structure. For example, the first interactive structure can be a part of an operating structure (for example, a handle), etc., so that the control system receives feedback information from the subject.

[0057] For step S200, for the initial position mark determined by step S100, the subject needs to identify the multiple sight marks 101 in the sight mark row 10 (for example, the 10th row) where the initial position mark is located one by one, and feedback the initial recognition result of each sight mark 101. For example, the subject can feedback the initial recognition result to the control system through the second interaction structure. For example, the second interaction structure can be integrated with the first interaction structure in the same operating structure, but is not limited to this. In some embodiments, the first interaction structure and the second interaction structure can be operating structures independent of each other. For a specific description of the first interaction structure and the second interaction structure, please refer to the relevant description of the following embodiments.

[0058] For step S300, after the subject has fed back all the initial recognition results, the test will continue according to the instructions of the control system. For example, the subject needs to continue to identify multiple sight marks in other sight mark rows 10 according to the instructions of the control system until the adjacent first specific sight mark row and second specific sight mark row are determined. For example, the subject can provide result feedback through the second interactive structure after identifying each sight mark 101. For example, the first specific sight mark row can be the 10th row, and the second specific sight mark row can be the 11th row, that is, the subject can correctly identify all sight marks 101 in the 10th row, and the subject's recognition result for at least one sight mark 101 in the 11th row is wrong. For example, when the vision result is expressed in numerical values, and the larger the numerical value, the better the vision result, the vision result corresponding to the second specific sight mark row is better than the vision result corresponding to the first specific sight mark row, which means that the vision value corresponding to the second specific sight mark row is greater than the vision value corresponding to the first specific sight mark row.

[0059] It should be noted that, in the embodiments of the present disclosure, the i-th row of sight marks means that the position in the row of sight marks is marked as i, where i is a positive integer.

[0060] For step S400: After determining to obtain the first specific sight mark row and the second specific sight mark row through the above step S300, the vision result corresponding to the first specific sight mark row can be obtained accordingly. The vision result can represent the vision value of the sight mark row, such as 4.8, 4.9 or 5.0. Since the recognition result of the subject for at least part of the sight marks in the second specific sight mark row is wrong, the number of sight marks in the second specific sight mark row for which the subject has a correct recognition result can be obtained accordingly, such as 2, 3 or 4. Finally, the vision test result of the subject can be calculated based on the vision result corresponding to the above-mentioned first specific sight mark row and the number of sight marks in the second specific sight mark row for which the recognition result is correct. For the calculation method of the vision test result, please refer to the relevant description of the following embodiment.

[0061] The vision detection method provided by the embodiments of the present disclosure is based on the initial position marker corresponding to the estimated vision of the subject to obtain multiple initial recognition results, thereby determining the first specific visual mark row and the second specific visual mark row, and then obtaining the vision detection result. The vision detection method is simple and easy, and can save a lot of manpower and material resources, and can effectively ensure the timeliness and accuracy of vision monitoring.

[0062] For example, Figure 2 As shown, the direction of each sight mark row 10 is a first direction X, and the arrangement direction of the multiple sight mark rows 10 is a second direction Y. In the second direction Y, the size of the position mark 102 is larger than the size of each sight mark 101 in the sight mark row 10 where the position mark 102 is located.

[0063] Such an arrangement allows the subject to easily identify the position mark corresponding to the smallest row of sight marks that can be seen clearly based on the estimated vision, thereby reducing unnecessary multiple feedback and confirmation processes to improve the efficiency of vision testing.

[0064] Figure 3 for Figure 1 FIG. 1 is a schematic diagram of an example of step S300 shown in FIG.

[0065] For example, Figure 2 As shown, the multiple vision results corresponding to the multiple sight mark rows in the first vision chart change row by row. For example, from row 7 to row 14, the vision results of each sight mark row 10 are gradually optimized. For example, the vision result corresponding to the sight mark in row 8 is better than the vision result corresponding to the sight mark in row 7, and the vision result corresponding to the sight mark in row 9 is better than the vision result corresponding to the sight mark in row 8.

[0066] For example, Figure 2As shown, the first vision chart also includes at least one first sight mark row 111 and at least one second sight mark row 112, the vision result corresponding to the first sight mark row 111 is better than the vision result corresponding to the sight mark row where the initial position mark is located, and the vision result corresponding to the sight mark row where the initial position mark is located is better than the vision result corresponding to the second sight mark row. For example, the first vision chart may include multiple first sight mark rows 111 and multiple second sight mark rows 112. For example, when the estimated vision of the subject corresponds to the 10th row of sight marks, the 11th row of sight marks, the 12th row of sight marks, the 13th row of sight marks, and the 14th row of sight marks in the first vision chart are all first sight mark rows 111, and the 7th row of sight marks, the 8th row of sight marks, and the 9th row of sight marks in the first vision chart are all second sight mark rows 112.

[0067] For example, Figure 3 As shown, Figure 1 The illustrated step S300 may include step S301 or step S302.

[0068] Step S301: In response to multiple initial recognition results being correct, the recognition results of multiple sight marks in the first sight mark row are fed back row by row in the order of increasing vision results until a first sight mark row whose recognition results include errors is found, and the first sight mark row is determined as the second specific sight mark row, and the first specific sight mark row is determined based on the second specific sight mark row.

[0069] Step S302: In response to j of the multiple initial recognition results being erroneous, starting from the sight mark row where the initial position marker is located, the recognition results of multiple sight marks in the second sight mark row are fed back row by row in the order of decreasing visual acuity results, where j is a positive integer, until a second sight mark row in which all the recognition results are correct is found, and the second sight mark row is determined as the first specific sight mark row, and the second specific sight mark row is determined based on the first specific sight mark row.

[0070] For example, Figure 2As shown, for step S301, taking the initial position mark 10 corresponding to the estimated vision of the examinee as an example, when the examinee can correctly identify all the optotypes 101 in the 10th row of optotypes, it is necessary to feedback the recognition results of the multiple optotypes 101 in the multiple first optotype rows 111 row by row. For example, it is necessary to first feedback the recognition results of the multiple optotypes 101 in the 11th row of optotypes, and when the examinee can correctly identify all the optotypes 101 in the 11th row of optotypes, then continue to feedback the recognition results of the multiple optotypes 101 in the 12th row of optotypes until a row of optotypes 101 is found that the examinee fails to correctly recognize all of them. For example, when the examinee fails to correctly recognize all the optotypes 101 in the 12th row of optotypes, that is, the examinee's recognition results for at least some of the optotypes 101 in the 12th row of optotypes are wrong, then the 12th row of optotypes is determined as the second specific optotype row. Since the second specific sight mark row is adjacent to the first specific sight mark row, the recognition results of the multiple sight marks 101 in the first specific sight mark row are all correct, and the visual acuity result corresponding to the second specific sight mark row is better than the visual acuity result corresponding to the first specific sight mark row, so when the second specific sight mark row is determined, the first specific sight mark row can be determined. Figure 2 In the first visual acuity chart shown, when the second specific sight mark row is the 12th sight mark row, the first specific sight mark row is the 11th sight mark row.

[0071] For example, Figure 2 As shown, for step S302, taking the initial position mark 10 corresponding to the estimated vision of the examinee as an example, when the examinee fails to correctly identify all the sight marks 101 in the 10th row of sight marks, it is necessary to start from the sight marks in the 10th row, in the order of decreasing vision results, according to the number of sight marks that the examinee has incorrectly identified in the 10th row of sight marks, for example, j, and start from the sight mark row that is j-1 rows away from the 10th row, and feedback the recognition results of multiple sight marks in each sight mark row row. For example, if the number of sight marks that the examinee has incorrectly identified in the 10th row of sight marks is 1, start from the 9th row that is 0 rows away from the 10th row; if the number of sight marks that the examinee has incorrectly identified in the 10th row of sight marks is 2, start from the 8th row that is 1 row away from the 10th row, and feedback the recognition results corresponding to the sight marks in each row row row by row, until a row of sight marks 101 is found so that the examinee can correctly identify all of them. The greater the number of optotypes that the examinee identifies incorrectly, the greater the difference between the examinee's estimated vision and his actual vision, which means that the examinee's actual vision may be worse. Therefore, when the examinee identifies more optotypes incorrectly, by feeding back the recognition results of multiple optotypes in each optotype row in the order of decreasing vision results, it is in line with the trend of finding the examinee's actual vision, making it easier for the examinee to find a row of optotypes that can be correctly recognized.

[0072] For example, Figure 2As shown in the figure, when the subject can correctly identify all the sight marks 101 in the 8th row of sight marks, that is, the subject's recognition results for all the sight marks 101 in the 8th row of sight marks are correct, then the 8th row of sight marks is determined as the first specific sight mark row. Since the second specific sight mark row is adjacent to the first specific sight mark row, the recognition results of at least some of the sight marks 101 in the second specific sight mark row are wrong, and the visual acuity result corresponding to the second specific sight mark row is better than the visual acuity result corresponding to the first specific sight mark row, when the first specific sight mark row is determined, the second specific sight mark row can be determined. For example, in Figure 2 In the first visual acuity chart shown, when the first specific sight mark row is the 8th sight mark row, the second specific sight mark row is the 9th sight mark row.

[0073] The process of determining the first specific visual mark row and the second specific visual mark row in the above manner does not require the guidance of professionals. The person being tested only needs to feedback the recognition results under the guidance of the control system, and then can interact with the control system. Therefore, the vision detection process is highly simple and practical, which can save human resources for professional testers and achieve the purpose of self-examination. In addition, the detection method is interesting. For example, the person being tested can be like playing an electronic game, making him or her willing to take a vision test. At the same time, the result feedback of the person being tested directly interacts with the control system, so that the standard for vision judgment is objective, thereby avoiding the subjective judgment of the person being tested by professional testers and making the standard for judging the vision level unified.

[0074] For example, Figure 2 As shown, the number of the multiple sight marks 101 in each sight mark row 10 in the first eye chart is n, where n is a positive integer. That is, each sight mark row 10 contains the same number of sight marks 101. For example, the sizes of the sight marks 101 in different sight mark rows 10 are different.

[0075] Thus, in the embodiment of the present disclosure, even if the sizes of the sight marks in different sight mark rows are different, the number of sight marks is the same, so that each sight mark represents the same vision meaning, that is, in the process of determining the vision of the subject, each sight mark has the same vision detection effectiveness.

[0076] For example, Figure 2 As shown, when the first specific sight mark row and the second specific sight mark row have been determined, the visual acuity result corresponding to the first specific sight mark row can be obtained, which is represented by a number A, and the number of sight marks with correct recognition results in the second specific sight mark row is B, then the visual acuity test result of the subject can be determined as A+B×(1 / n). For example, when the visual acuity result A corresponding to the first specific sight mark row is 4.9, the number of sight marks with correct recognition results in the second specific sight mark row is 2, and each sight mark row 10 includes 5 sight marks 101, then the visual acuity test result of the subject is 4.9+2×(1 / 5), that is, 4.94.

[0077] Generally, the expression of vision includes fractional recording method, decimal recording method, LogMar recording method, also known as logarithmic recording method, and 5-point recording method. For example, the fractional recording method is usually expressed as "X / Y", where X represents the number of visual acuity lines that the subject can see clearly, and Y represents the number of visual acuity lines that a person with normal vision can see clearly. For example, "20 / 20" means that the subject's vision is the same as normal vision. For example, the decimal recording method usually takes 1.0 as the normal vision standard. In the decimal recording method, the closer the vision value is to 1.0, the better the vision. For example, the LogMar recording method is a visual acuity expression method based on a logarithmic scale, which is usually used in scientific research and statistical analysis. In this recording method, the smaller the vision value is, the better the vision is. For example, "0.0" represents perfect vision, and "0.1" represents slightly worse vision. For example, the 5-point recording method takes 5.0 as the normal vision standard. The closer the vision value is to 5.0, the better the vision is. Although different expression methods can be converted through functional equations, the conversion is inconvenient. For example, when it is necessary to use the subject's 1.0 vision test result for scientific research, the vision test result can only be recorded in the form of a logarithmic method or a 5-point recording method.

[0078] Therefore, the embodiment of the present disclosure preferably adopts the 5-point recording method, which can not only accurately express the vision test results to the subject, in line with the idea that "the higher the score, the better the vision", but also is more suitable for data analysis, so as to compare whether the vision has changed before and after the measurement, and confirm whether it is necessary to go to an optometry hospital for treatment.

[0079] Figure 4 A schematic diagram of an operating structure provided for at least one embodiment of the present disclosure.

[0080] For example, Figure 4 As shown, the subject can perform vision testing by controlling the operating structure. For example, the operating structure may include a voice prompt structure 120, and the operating structure is communicatively connected to the control system. For example, the subject can receive a voice prompt from the voice prompt structure 120 of the operating structure. Before determining the initial position identifier corresponding to the estimated vision of the subject, the subject can be located at the detection position according to the voice prompt. For example, the detection position is configured as the position when the subject is tested, and there is a detection distance between the detection position and the first vision chart. Thereby, the subject can be located at an appropriate position for vision testing according to the voice prompt, thereby reducing dependence on professional testers.

[0081] For example, the detection distance between the detection position and the first vision chart may be 4 to 6 meters, such as 5 meters, or 5 to 6 meters, which is not limited in the embodiments of the present disclosure.

[0082] Such a setting can realize the detection of the distance vision of the subject. For example, the vision detection method provided by the embodiment of the present disclosure can be applied to campus, for example, the distance vision of young students can be monitored in time, so that the occurrence of myopia can be prevented in time and effectively.

[0083] For example, Figure 2 and Figure 4 As shown, step S100 may include: triggering a first interaction structure corresponding to the initial position identifier in the operating structure. For example, the operating structure includes a plurality of first interaction structures 130, and the plurality of first interaction structures 130 correspond one-to-one to a plurality of position identifiers 102 in the first vision chart. For example, the operating structure may be a handle. The plurality of first interaction structures 130 may be a plurality of buttons in the operating structure, for example, the plurality of position identifiers 102 in the first vision chart are a plurality of different positive integers, and the first interaction structure 130 has a digital identifier, which is the same as the position identifier 102 in the vision row 10 in the first vision chart. The subject may trigger (for example, by pressing a button) a first interaction structure 130 in the operating structure to select the initial position identifier in the first vision chart corresponding to the estimated vision, so that the vision detection process is efficient. For example, when determining the initial position identifier, the subject has only one chance and cannot repeatedly identify the trigger to ensure the accuracy of the detection.

[0084] In some embodiments, the position mark in the first vision chart and the first interactive structure in the operation structure may also be represented in other ways, for example, they may include at least one of Chinese characters, numbers and English letters. For example, Chinese characters may include at least one font. For example, the position mark in the first vision chart may also use different geometric shapes, animal shapes, etc., as long as it is convenient for the subject to determine the initial position mark corresponding to the estimated vision. The embodiments of the present disclosure are not limited to this, and the specific selection can be made according to design needs.

[0085] For example, Figure 2 and Figure 4 As shown, step S200 may include: triggering different parts of the second interaction structure to feedback the recognition results of each sight mark. For example, the operation structure also includes a second interaction structure 140. The second interaction structure 140 includes parts corresponding to the features of each sight mark 101 in the first vision chart, so that the subject can trigger different parts of the second interaction structure 140 to feedback the recognition results of the sight mark 101.

[0086] For example, Figure 2 and Figure 4As shown, the second interactive structure 140 is a cross structure. The second interactive structure 140 includes a first part 1401, a second part 1402, a third part 1403 and a fourth part 1404. For example, the multiple sight marks 101 in the first eye chart include four types, and each sight mark 101 is in the shape of "E". According to the different orientations of the multiple sight marks 101, take the sight marks in the 7th row as an example, Figure 2 From left to right, the first sight mark 101 corresponds to the third part 1403, the second sight mark 101 corresponds to the second part 1402, the third sight mark 101 corresponds to the fourth part 1404, the fourth sight mark 101 is in the same position as the first sight mark 101 and corresponds to the third part 1403, and the fifth sight mark 101 corresponds to the first part 1401. The corresponding manner of each sight mark 101 in other sight mark rows 10 in the first vision chart and the second interactive structure 140 is similar, and will not be described repeatedly here.

[0087] In some embodiments, the second interaction structure may also be in other forms. For example, the second interaction structure may include a plurality of spaced-apart portions, and the plurality of spaced-apart portions correspond to the sight marks in the first vision chart, respectively. For example, the plurality of spaced-apart portions may be located at different positions in the operating structure and may have different shapes, which is not limited in the embodiments of the present disclosure.

[0088] In some embodiments, the first interaction structure may also be set independently of the second interaction structure, which is not limited in the embodiments of the present disclosure.

[0089] For example, the vision detection method provided by at least one embodiment of the present disclosure may further include: viewing the vision detection result in the cloud structure. For example, the operation structure, the display structure, and the cloud structure are connected in communication with each other, and the first vision chart is located in the display structure. (For example, refer to Fig. 9 The operation structure 234 is connected to the display structure 160 in communication, the display structure 160 is connected to the cloud structure 150 in communication, and the cloud structure 150 is connected to the display structure 160 in communication. For details, please refer to the following embodiments regarding Fig. 9 For example, after the test is completed, the subject can view his or her vision test results through the cloud structure. For example, the cloud structure may include a computer, a mobile phone, etc. For example, the subject can enter a program in a mobile phone or computer and enter personal account information to enter the viewing interface of the program. In other words, only relevant personnel with account authority can view the subject's vision test results.

[0090] For example, the cloud structure can also combine relevant information of the examinee, such as the examinee's height, gender, family situation, and the vision level of relatives, to generate a comprehensive vision analysis report for the examinee, so as to indicate the examinee's potential risks while displaying the examinee's objective vision level, and provide corresponding preventive measures.

[0091] In some embodiments, the visual acuity test results of the subject can be stored and archived in the remote structure, and the latest visual acuity test results can be analyzed and compared with the previous visual acuity test results, so as to facilitate the designation of personalized myopia prevention and control measures for the subject. For example, a relationship table between naked eye visual acuity and myopia degree similar to Egger's Chart can be made by performing big data analysis. For example, the visual acuity test results can also be remotely transmitted and monitored.

[0092] For example, since the recognition speed of the examinee should also be a factor in determining the quality of vision, the shorter the time required, the faster the vision recognition. Therefore, the above vision analysis report can also reflect the examinee's response time to the visual mark line (for example, the first specific visual mark line) to reflect the examinee's reaction speed. For example, by comparing with the average reaction speed (for example, the average reaction speed can be preset in the cloud structure), the examinee's reaction ability can be explained to the examinee, and thus the examinee's vision level can also be reflected.

[0093] In this way, the privacy of the person being tested can be effectively guaranteed, making the individual's vision test results private and comprehensive.

[0094] Figure 5 A schematic diagram of a single-row sight mark provided for at least one embodiment of the present disclosure.

[0095] For example, Figure 2 and Figure 5 As shown, for step S301 and step S302, in the process of determining the first specific optotype row and the second specific optotype row, the multiple optotypes 101 of the first optotype row 111 and the multiple optotypes 101 of the second optotype row 112 are respectively displayed in the single-row display mode as a part of the single-row optotype 010. For example, the single-row optotype 010 includes a frame 0101, and the multiple optotypes 101 in one of the first optotype row 111 and the second optotype row 112 in the frame 0101.

[0096] For example, Figure 2 and Figure 5 As shown, when the first sight mark row 111 or the second sight mark row 112 needs to be displayed to the subject, it is displayed only in a single row. For example, when the 11th row of sight marks needs to be displayed to the subject, the displayed single row of sight marks 010 includes multiple sight marks 101 in the 11th row of sight marks and a frame 0101.

[0097] In the single-line display mode, since the single-line time mark has a border, the border can be used as a crowding element, that is, the vision detection method provided in the embodiment of the present disclosure takes into account the impact of crowding on the vision of the subject to improve the accuracy of vision detection.

[0098] For example, Figure 2 and Figure 5 As shown, the single-line sight mark 010 does not include the position mark 102. This arrangement can make the examinee unclear about which line of the first vision chart the currently displayed sight mark is located, thereby reducing the examinee's psychological pressure and facilitating the authenticity and privacy of vision testing.

[0099] For example, Figure 5 As shown, the frame 0101 includes a first frame portion 0111 and a second frame portion 0112, and a third frame portion 0113 and a fourth frame portion 0114. The first frame portion 0111 and the second frame portion 0112 both extend in the first direction X, and the third frame portion 0113 and the fourth frame portion 0114 both extend in the second direction Y. The first frame portion 0111 includes a plurality of first sub-frame portions 0001, and the plurality of first sub-frame portions 0001 are arranged at intervals in the first direction X, and each first sub-frame portion 0001 extends in the first direction X. The second frame portion 0112 includes a plurality of second sub-frame portions 0002, and the plurality of second sub-frame portions 0002 are arranged at intervals in the first direction X, and each second sub-frame portion 0002 extends in the first direction X. The third frame portion 0113 includes at least one third sub-frame portion 0003 , and the fourth frame portion 0114 includes at least one fourth sub-frame portion 0003 . Both the third sub-frame portion 0003 and the fourth sub-frame portion 0003 extend along the second direction Y.

[0100] For example, Figure 5 As shown, the first frame portion 0111, the second frame portion 0112, the third frame portion 0113 and the fourth frame portion 0114 together form a frame 0101. For example, the frame 0101 is rectangular, but is not limited thereto.

[0101] For example, Figure 5 As shown, in the second direction Y, the multiple sight mark rows 10 in the first vision chart include a first adjacent sight mark row and a second adjacent sight mark row respectively adjacent to the sight mark row 10 where the multiple sight marks 101 in the single-line sight mark 010 are located, and the visual acuity result corresponding to the second adjacent sight mark row is better than the visual acuity result corresponding to the first adjacent sight mark row. For example, when the single-line sight mark 010 displays the 10th row of sight marks in the first vision chart, the first adjacent sight mark row is the 9th row of sight marks, and the second adjacent sight mark row is the 11th row of sight marks.

[0102] For example, Figure 2and Figure 5 As shown, the size of the first sub-frame portion 0001 in the first direction X is the same as the size of each sight mark 101 in the first adjacent sight mark row, and the size of the first sub-frame portion 0001 in the second direction Y is 1 / 6 to 1 / 4, such as 1 / 5, of the size of the first sub-frame portion 0001 in the first direction X. The number of the plurality of first sub-frame portions 0001 in the first frame portion 0111 is equal to the number of the plurality of sight marks 101 in the sight mark row 10. For example, the plurality of first sub-frame portions 0001 and the plurality of sight marks 101 in the frame 0101 have a first relative positional relationship, and the plurality of sight marks 101 in the first adjacent sight mark row and the plurality of sight marks 101 in the frame 0101 have a second relative positional relationship, and the first relative positional relationship is the same as the second relative positional relationship.

[0103] For example, Figure 2 and Figure 5 As shown, the size of the second sub-frame portion 0002 in the first direction X is the same as the size of each sight mark 101 in the second adjacent sight mark row, and the size of the second sub-frame portion 0002 in the second direction Y is 1 / 6 to 1 / 4, such as 1 / 5, of the size of the second sub-frame portion 0002 in the first direction X. For example, a third relative position relationship exists between the plurality of second frame portions 0112 and the plurality of sight marks 101 in the frame 0101, a fourth relative position relationship exists between the plurality of sight marks 101 in the second adjacent sight mark row and the plurality of sight marks 101 in the frame 0101, and the third relative position relationship is the same as the fourth relative position relationship.

[0104] For example, Figure 2 and Figure 5 As shown, the third sub-frame portion 0003 and the fourth sub-frame portion 0004 have a first size in the second direction Y, and the first size is the same as the size of the visual mark 101 in the frame 0101 in the second direction Y. The third sub-frame portion 0003 and the fourth sub-frame portion 0004 have a second size in the first direction X, and the second size is 1 / 6 to 1 / 4 of the first size, such as 1 / 5.

[0105] With such an arrangement, when performing single-line display, the position matching effect between a row of visual marks displayed and the frame can be close to the position matching effect between the row of visual marks and the adjacent row of visual marks in the first eye chart. This helps to make the "crowding effect" during single-line display more consistent with the "crowding effect" when displaying using the first eye chart, and helps to enhance the accuracy of vision testing.

[0106] It should be noted that the embodiments of the present disclosure do not limit the form of the first vision chart. In some embodiments, multiple sets of vision charts can be displayed to perform vision testing, thereby effectively preventing the subject from memorizing the vision charts to ensure the accuracy of vision testing.

[0107] For example, when the above detection method is used to complete the measurement of one eye of the subject, the same detection process can be used for the other eye, and the specific description is not repeated.

[0108] For example, in order to make the vision testing process more comprehensive, other vision measurements may be performed on the subject.

[0109] Figure 6 A schematic diagram of a second vision chart provided for at least one embodiment of the present disclosure.

[0110] For example, when the vision test result obtained by the subject after the vision test process is greater than or equal to the first threshold, the vision test of the subject can be terminated. For example, the first threshold can be not less than 5.0, but is not limited thereto, and the embodiments of the present disclosure do not limit this.

[0111] For example, when the visual acuity test result obtained by the subject after the visual acuity test is less than the first threshold, it means that the visual acuity of the subject does not meet the standard. Then, it is necessary to use a second visual acuity chart for visual acuity testing. The visual acuity testing method provided by the embodiment of the present disclosure may also include: feeding back the clarity of the first part of the visual acuity chart and the second part of the visual acuity chart in each row.

[0112] For example, Figure 6 As shown, the second eye chart includes multiple rows of optotypes, each row of optotypes includes multiple first partial optotypes 310 and multiple second partial optotypes 320, the background of the first partial optotypes 310 is green, and the background of the second partial optotypes 320 is red. For example, the multiple optotypes 101 in each row of optotypes have the same size in the first direction X and the same size in the second direction Y. For example, in the same row of optotypes, the first partial optotypes 310 and the second partial optotypes 320 may include the same number of optotypes 101.

[0113] For example, Figure 6As shown, for the same row of sight marks, when the subject believes that the clarity of the first part of the sight mark 310 is greater than the clarity of the second part of the sight mark 320, a risk warning of overcorrection or accommodation lag can be obtained. For example, overcorrection means that the degree of glasses or contact lenses may be too high, or the eyes have a high degree of hyperopia without correction. Accommodation lag means that the eye's accommodation function may be insufficient, resulting in insufficient accommodation when looking at close objects. For example, when the subject believes that the first part of the sight mark 310 or the second part of the sight mark 320 in the same row is more blurred (for example, has double images, etc.), it is believed that the clarity of the corresponding sight mark is lower.

[0114] For example, Figure 6 As shown, for the same sight mark line, when the examinee thinks that the clarity of the first part sight mark 310 is less than the clarity of the second part sight mark 320, a risk warning of undercorrection or over-adjustment can be obtained. For example, undercorrection means that the degree of glasses or contact lenses is not enough, or the myopia of the eyes is high without correction. For example, over-adjustment means that the eye's accommodation function may be too strong, resulting in over-adjustment when looking at close objects.

[0115] In some embodiments, if the subject believes that the first portion of the optotype 310 and the second portion of the optotype 320 have the same clarity, the subject may have poor vision due to organic lesions.

[0116] By adding the detection of red and green visual marks to the subjects whose vision detection results are less than the first threshold, the vision condition of the subjects can be more comprehensively understood.

[0117] Figure 7 A schematic diagram of a third vision chart provided for at least one embodiment of the present disclosure.

[0118] For example, when the vision test result obtained by the subject through the above vision test is less than the second threshold, it is necessary to use the second vision chart to perform the vision test and then use the third vision chart to perform the vision test. The vision detection method provided by the embodiment of the present disclosure may also include: obtaining the corresponding vision detection result based on the third vision chart. For example, the second threshold is less than the first threshold, the first threshold may be, for example, 5.0, and the second threshold may be, for example, 4.9, but is not limited thereto.

[0119] For example, Figure 2 and Figure 7 As shown, the multiple lines of visual marks on the first visual chart are black, and the background of the first visual chart is white. The multiple lines of visual marks on the third visual chart are white, and the background of the third visual chart is black. For example, the difference between the third visual chart and the first visual chart is that the background color is different and the visual mark color is different, and the other features are the same.

[0120] For example, Figure 7As shown, the subject can use the third vision chart to perform the vision test process described in the above embodiment. If the vision test result obtained by the subject using the third vision chart for vision test is better than the vision test result obtained by using the first vision chart, a risk warning of turbidity of the refractive medium (such as cornea, lens, etc.) can be obtained. For example, turbidity of the refractive medium will affect the normal conduction of light and cause decreased vision. For example, if the vision test result obtained by the subject using the third vision chart for vision test is basically equal to the vision test result obtained by using the first vision chart, a risk warning of refractive error or organic lesions can be obtained.

[0121] The vision condition of the patient can be further assessed by using a black-and-white inverted sight mark for the subject whose vision test result is less than the second threshold value. According to the change in vision, the vision problem of the subject can be determined more comprehensively.

[0122] Figure 8 A schematic diagram of a fourth vision chart provided for at least one embodiment of the present disclosure.

[0123] For example, Figure 2 As shown, when the subject uses the first eye chart to perform vision testing, for example, in the process of determining the above-mentioned first specific sight mark row and the second specific sight mark row, if it is found that the subject's recognition results corresponding to multiple sight mark rows include correct and incorrect, the vision testing method provided by the embodiment of the present disclosure may also include: performing an astigmatism test based on a fourth eye chart.

[0124] For example, Figure 2 As shown, when the subject is unable to correctly identify all the sight marks 101 in the sight mark row where the initial position mark is located, when looking for a row of sight marks 101 that can be correctly identified in full from multiple second sight mark rows 112, the subject has sight marks that can be correctly identified and sight marks that cannot be correctly identified during the identification process of multiple rows of sight marks, then the subject needs to be tested for astigmatism.

[0125] For example, Figure 8 As shown, when the visual acuity test is performed according to the fourth visual acuity chart, it can be detected whether the subject has a direction preference. For example, the fourth visual acuity chart can be an astigmatism disc. For example, when the subject thinks that the lines extending along the first direction X are clearer, the subject may squint or have anti-axis astigmatism. For example, when the subject thinks that the lines extending along the second direction Y are clearer, the subject may have anti-axis astigmatism.

[0126] By using an astigmatism disc to test the subject's astigmatism, the subject's vision can be more comprehensively evaluated from the perspective of whether the subject has astigmatism.

[0127] For example, if the subject's vision test results are poor after the above-mentioned vision tests, the subject may be prompted to undergo an examination by an optometrist to find out the cause.

[0128] For example, Figure 2 What is shown may be a part of the first vision chart. For example, the range of vision results corresponding to the multiple sight mark rows in the first vision chart is: 3.7-5.3, and the vision level of the subject is positively correlated with the vision test result. With such a setting, the first vision chart can have a larger vision test range, for example, it can include from low vision to super vision, so as to be suitable for more people to be tested.

[0129] Usually, for some eye charts, the 5.0 line sight mark usually represents the normal vision level and is an important reference point in vision testing. Regarding the relationship between the subject's line of sight and the sight mark on the eye chart, the subject's line of sight is usually required to be at the same height as a certain line on the eye chart (such as the 5.0 line). This is to ensure that the subject's ability to recognize sight marks of different sizes can be accurately observed. If the subject's line of sight is not at the same height, it may affect the judgment of the vision condition.

[0130] In the vision detection method provided by at least one embodiment of the present disclosure, since the above-mentioned single-line display mode is adopted, it is easy to make the subject's line of sight and each sight mark in the single-line sight mark maintain the same height, which is conducive to accurately observing the subject's ability to recognize sight marks of different sizes.

[0131] For example, Figure 2 As shown, in the Y direction, the height P1 of the kth sight mark row, the distance P2 between the kth sight mark row and the k+1th sight mark row, and the height P3 of the k+1th sight mark row are distributed in geometric series, k is a positive integer. For example, P2 = P1 / W1, P3 = P1 / W2, and the above-mentioned geometric series distribution means that the values ​​of P1 and P2 are distributed in geometric series, and the values ​​of P1 and P3 are distributed in geometric series.
