Description

Technical Field

[0001] This invention relates to the field of vision testing, and more specifically, to a vision testing method, apparatus, electronic device, and storage medium. Background Technology

[0002] As more and more people start using electronic products, people's eyesight has been greatly affected. The first thing to do in treating vision problems is to check people's vision.

[0003] Currently, the main method is to manually test each person's vision at a fixed distance. This manual testing is inefficient and inaccurate. In addition, this method can only test each person's visual acuity and cannot detect the deformation of each person's axial length, which is an important basis for determining each person's glasses prescription. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a vision testing method, device, electronic device and storage medium that can accurately determine the user's axial length deformation and / or degree of hyperopia.

[0005] In a first aspect, embodiments of this application provide a vision testing method, which includes:

[0006] Obtain the user's visual acuity at different distances from the test target, and the corresponding test target size; the distance includes the reference distance and non-reference distance;

[0007] Based on the test target size corresponding to the reference distance, determine the corresponding health target size for the user at non-reference distances;

[0008] The target distance is determined from the non-reference distance by comparing the test target size and the healthy target size corresponding to the non-reference distance;

[0009] Based on the target distance and the preset standard axial length, determine the user's axial deformation and / or degree of hyperopia.

[0017] If the test target size and health target size are different for all non-reference distances, then the shortest distance among all non-reference distances is determined as the target distance.

[0018] Otherwise, the target distance is determined from the non-reference distances by comparing the test target size and the healthy target size corresponding to the smallest distance among the non-reference distances.

[0021] If the test target size and the health target size are the same for the smallest non-reference distance, the longest distance among all non-reference distances with the same test target size and health target size is determined as the target distance.

[0022] If the test target size and the health target size are different among the minimum non-reference distances, the shortest distance among all non-reference distances with the same test target size and health target size is determined as the target distance.

[0023] In one possible implementation, the user's axial length deformation is determined based on the target distance and a preset standard axial length, including:

[0025]

[0026] Where α is the axial length deformation, ν is the preset standard axial length, and u is the target distance.

[0027] In one possible implementation, determining the user's degree of farsightedness based on the target distance and a preset standard axial length includes:

[0049] For the test target display interface, the direction of the test target is input by the user through an input device at different distances from the test target.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0090] To enable those skilled in the art to utilize the content of this application, and in conjunction with the specific application scenario of "vision testing," the following implementation is provided. For those skilled in the art, the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of this application. Although this application is primarily described in the context of "vision testing," it should be understood that this is merely an exemplary embodiment.

[0091] It should be noted that the term "comprising" will be used in the embodiments of this application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0092] The following is a detailed description of a vision testing method provided in the embodiments of this application.

[0093] Reference Figure 1 The diagram shown is a schematic flowchart of a vision testing method provided in an embodiment of this application. The exemplary steps of this embodiment are described below:

[0094] S101. Obtain the user's visual acuity at different distances from the test target, and the size of the test target corresponding to the visual acuity.

[0095] In this embodiment, the distance includes a reference distance and a non-reference distance. The test visual acuity of the user at both the reference and non-reference distances from the test target, and the corresponding test target size, are obtained. Here, the obtained test visual acuity and corresponding test target size at both the reference and non-reference distances are the same as the test visual acuity and corresponding test target size obtained by the user at both the reference and non-reference distances.

[0096] There is only one reference distance, but there can be multiple non-reference distances.

[0097] Specifically, a test target display interface corresponding to the user is displayed on a human-computer interaction display device; for the test target display interface, the direction of the target input by the user at different distances from the test target is received through an input device; based on the target direction input by the user and the actual target direction of the test target, the test visual acuity corresponding to the user at different distances from the test target and the test target size corresponding to the test visual acuity are determined.

[0098] Input devices can include remote controls, mobile apps, wireless keyboards, etc.

[0099] Here, the human-computer interaction display device simultaneously displays multiple test target display interfaces, each for a single user's vision test. In other words, this application can perform vision tests for multiple users simultaneously. When testing a user's vision, the user stands at a designated distance from their corresponding test target display interface. The interface sequentially displays test targets of various sizes. The user inputs the direction of each test target size displayed. Based on the user's input direction and the actual direction of the test target, the user's visual acuity at that designated distance and the corresponding test target size are obtained. The user then moves to the next distance and performs the test again.

[0100] Furthermore, the number of steps a user needs to move to the next distance can be determined based on the user's historical step count data. For example, if historical data shows that the user moves 3 steps to 1 meter, and the user needs to move 1.5 meters to the next distance, then the user needs to take 1.5 ÷ (1 ÷ 3) steps.

[0101] Furthermore, the distance from the user to the test target in the test target display interface can also be calculated based on the size of the input device in the user's hand.

[0102] For example, the reference distance is 5 meters, and non-reference distances include 1 meter and 3 meters. The user's visual acuity is obtained at 1 meter, 3 meters, and 5 meters from the test target. If the user's visual acuity at 1 meter, 3 meters, and 5 meters from the test target is 4.1, 4.0, and 4.0, then the size of the test target corresponding to the visual acuity is the size of the target at the position of 4.1, 4.0, and 4.0 in the visual acuity chart.

[0103] S102. Based on the test target size corresponding to the reference distance, determine the health target size for the user at non-reference distances.

[0104] Specifically, the size of the health target is calculated using the following formula.

[0105]

[0106] Where y is the size of the health target, d1 is the reference distance, d2 is the non-reference distance, and s is the size of the test target.

[0107] Here, the theoretically healthy target size for the user at other non-reference distances is determined by using the test target size at the reference distance.

[0108] For example, if the baseline distance is 5 meters and the non-baseline distances include 1 meter and 3 meters, then the health target size for the user at 1 meter and 3 meters is determined based on the test target size corresponding to 5 meters. y is the health target size corresponding to 1 meter or 3 meters, d1 is 5 meters, d2 is 1 meter or 3 meters, and s is the test target size corresponding to 5 meters.

[0109] S103. Determine the target distance from the non-reference distance by comparing the test target size and the health target size corresponding to the non-reference distance.

[0110] In this embodiment of the application, by comparing the test target size obtained by the user at a non-reference distance with the theoretical healthy target size of the user at a non-reference distance, the target distance at which the user's eye accommodation begins to change can be determined.

[0111] Specifically, it is determined whether the test target size and the healthy target size corresponding to the non-reference distance are the same; if the test target size and the healthy target size corresponding to all non-reference distances are the same, the longest distance among all non-reference distances is determined as the target distance; if the test target size and the healthy target size corresponding to all non-reference distances are different, the shortest distance among all non-reference distances is determined as the target distance; otherwise, the target distance is determined from the non-reference distances by comparing the test target size and the healthy target size corresponding to the shortest distance among the non-reference distances.

[0112] Furthermore, determine whether the test target size and the healthy target size are the same for the smallest non-reference distance. If the test target size and the healthy target size are the same for the smallest non-reference distance, determine the longest distance among all non-reference distances with the same test target size and healthy target size as the target distance. If the test target size and the healthy target size are not the same for the smallest non-reference distance, determine the shortest distance among all non-reference distances with the same test target size and healthy target size as the target distance.

[0113] In this embodiment, if the test target size and the healthy target size are the same for the shortest non-reference distance, it can be determined that the user has no vision problems at near distances but has vision problems at far distances, therefore the user is myopic. The user's target distance should be the longest distance among all non-reference distances where the test target size and the healthy target size are the same. Conversely, if the test target size and the healthy target size are not the same for the shortest non-reference distance, it can be determined that the user has vision problems at near distances but no vision problems at far distances, therefore the user is hyperopic. The user's target distance should be the shortest distance among all non-reference distances where the test target size and the healthy target size are the same.

[0114] S104. Determine the user's axial length deformation and / or degree of hyperopia based on the target distance and the preset standard axial length.

[0115] Optionally, the axial length deformation can be calculated using the following formula.

[0116]

[0117] Where α is the axial length deformation, ν is the preset standard axial length, and u is the target distance.

[0118] Here, the preset standard axial length should be the axial length of most people with normal vision. The greater the axial deformation, the higher the degree of myopia.

[0119] Optionally, the degree of farsightedness can be calculated using the following formula.

[0120] b = (u / w)(w+v) / (u+v).

[0121] Where b is the degree of farsightedness, ν is the preset standard axial length, u is the target distance, and w is the preset farsighted distance.

[0122] Here, the preset farsightedness distance is generally set to 20cm. The larger the farsightedness parameter, the higher the degree of farsightedness.

[0123] This application provides a vision testing method, which includes: acquiring the user's test visual acuity at different distances from a test target, and the corresponding test target size; the distances include a reference distance and non-reference distances; determining the user's healthy target size at non-reference distances based on the test target size at the reference distance; determining a target distance from the non-reference distances by comparing the test target size at the non-reference distances with the healthy target size; and determining the user's axial length deformation based on the target distance and a preset standard axial length. This application determines the target distance using the test target size at non-reference distances and the corresponding healthy target size at non-reference distances determined based on the test target size at the reference distance. Then, based on the target distance and a preset standard axial length, it determines the user's axial length deformation and / or hyperopia degree. This method provides accurate and efficient vision testing and can accurately determine the user's axial length deformation and / or hyperopia degree.

[0124] Reference Figure 2 The diagram shown is a flowchart of another vision testing method provided in this application embodiment. Steps S202 and S203 are as follows: Figure 1 S102 and S103 in the above steps will not be described in detail here. The following describes the exemplary steps of the embodiments of this application:

[0125] S201. Obtain the test visual acuity of the user at different distances from the test target under different eye use durations, and the size of the first target corresponding to the test visual acuity.

[0126] The distance includes the baseline distance and the non-baseline distance.

[0127] Specifically, the historical target distance for each user is determined, and the test visual acuity is obtained at different distances from the test target within the historical target distance under different eye use durations.

[0128] In this application embodiment, the historical target distance obtained by the user in the previous vision test is determined, and the test vision corresponding to the user at different distances from the test target within the historical target distance under different eye use durations is obtained.

[0129] Here, the user's historical target distance is the distance at which the user's eye accommodation begins to change. Therefore, the factor affecting the user's vision within the historical target distance must be the duration of eye use.

[0130] For example, if the historical target distance is 4 meters, then all non-baseline distances are less than 4 meters.

[0131] S202. For each duration of eye use, determine the second visual target size corresponding to the user at a non-reference distance based on the first visual target size corresponding to the reference distance.

[0132] S203. By comparing the first and second target sizes corresponding to the non-reference distance, determine the target distance corresponding to the viewing time.

[0133] S204. Determine the user's optimal screen time based on the target distance corresponding to all screen time durations.

[0134] Specifically, all screen time durations are arranged from smallest to largest, and the screen time duration for which the target distance changes first is determined as the user's optimal screen time duration.

[0135] For example, if the screen time is 5 minutes, 10 minutes, 20 minutes, and 30 minutes, and the target distances corresponding to the screen time are 4 meters, 4 meters, 3 meters, and 2 meters, and the screen time for which the target distance first changes is 20 minutes, then the optimal screen time for the user is determined to be 20 minutes.

[0136] This application provides another vision testing method, which includes acquiring the test visual acuity of a user at different distances from the test target under different viewing durations, and the first optotype size corresponding to the test visual acuity; for each viewing duration, determining the second optotype size corresponding to the user at a non-reference distance based on the first optotype size corresponding to the reference distance; determining the target distance corresponding to the viewing duration by comparing the first and second optotype sizes corresponding to the non-reference distance; and determining the user's optimal viewing duration based on the target distances corresponding to all viewing durations. This method enables the determination of a user's optimal viewing duration.

[0137] Reference Figure 3 The diagram shown is a flowchart of another vision testing method provided in an embodiment of this application. Steps S302 and S303 are as follows: Figure 1 S102 and S103 are described below as exemplary steps in the embodiments of this application:

[0138] S301. Obtain the test visual acuity of the user at different distances from the test target under different ambient brightness conditions, and the size of the first target corresponding to the visual acuity.

[0139] The distance includes the baseline distance and the non-baseline distance.

[0140] Specifically, the historical target distance for the user is determined, and the test visual acuity of the user at different distances from the test target within the historical target distance is obtained under different ambient brightness conditions.

[0141] In this application embodiment, the historical target distance obtained by the user in previous vision tests is determined, and the test vision corresponding to the user at different distances from the test target within the historical target distance under different ambient brightness conditions is obtained.

[0142] Here, the user's historical target distance is the distance at which the user's eye accommodation begins to change. Therefore, the factor affecting the user's vision within the historical target distance must be ambient brightness.

[0143] S302. For each ambient brightness, based on the first target size corresponding to the reference distance, determine the second target size corresponding to the user at a non-reference distance under the ambient brightness.

[0144] S303. By comparing the first and second target sizes corresponding to the non-reference distance, determine the target distance corresponding to the ambient brightness.

[0145] S304. Determine the optimal ambient brightness for the user based on the target distance corresponding to all ambient brightness levels.

[0146] Specifically, all ambient brightness levels are arranged from smallest to largest, and the ambient brightness level at which the target distance changes first is determined as the user's optimal ambient brightness.

[0147] For example, the ambient brightness is arranged from smallest to largest as a, b, c, d, and the target distances corresponding to the ambient brightness are 4 meters, 4 meters, 3 meters, and 2 meters, respectively. The ambient brightness whose target distance changes first is c, and the optimal ambient brightness for the user is determined to be c.

[0148] This application provides another vision testing method, which includes acquiring the test visual acuity of a user at different distances from a test target under different ambient brightness levels, and the corresponding first optotype size; for each ambient brightness level, determining the second optotype size corresponding to the user at a non-reference distance based on the first optotype size corresponding to a reference distance; determining the target distance corresponding to the ambient brightness level by comparing the first and second optotype sizes corresponding to the non-reference distances; and determining the user's optimal ambient brightness based on the target distances corresponding to all ambient brightness levels.
