Referring to FIG. 1 , which is a schematic flowchart of a vision detection method provided by the embodiment of the present application, the exemplary steps of the embodiment of the present application are described below:

S101. Obtain the corresponding test visual acuity of the user at different distances from the test visual target, and the test visual target size corresponding to the test visual acuity.

In the embodiment of the present application, the distance includes a reference distance and a non-reference distance, and the user's test vision corresponding to the reference distance and the non-reference distance from the test visual target, and the test visual target size corresponding to the test visual acuity are obtained. Here, the obtained user's test vision corresponding to the reference distance and the non-reference distance from the test visual target, and the test visual target size corresponding to the test visual acuity are the test visual acuity obtained by the user's test respectively at the reference distance and the non-reference distance, And test visual acuity corresponding to the test target size.

Among them, there is only one reference distance, and there may be multiple non-reference distances.

Specifically, display the test optotype display interface corresponding to the user in the human-computer interaction display device; for the test optotype display interface, receive the direction of the visual target input by the user through the input device at different distances from the test visual target; according to the user input The direction of the visual target and the real visual target direction of the test visual target determine the test visual acuity corresponding to the user at different distances from the test visual target, and the test visual target size corresponding to the test visual acuity.

Wherein, the input device may be a remote controller, an app in a mobile phone, a wireless keyboard, and the like.

Here, multiple test optotype display interfaces are simultaneously displayed on the human-computer interaction display device, and each test optotype display interface performs vision testing for a user, that is to say, the application can simultaneously perform vision testing for multiple users. When testing eyesight for a user, the user stands at a specified distance from the test optotype display interface corresponding to the user, and the test optotype display interface displays test optotypes of various sizes in turn, and the user for each test optotype displayed on the test optotype display interface. A test target of a size Input the direction of the test target, according to the direction of the target input by the user and the real direction of the test target, the user's test vision at the specified distance and the test target size corresponding to the test vision can be obtained . The user then runs the test again at the next distance.

Further, the number of steps required for the user to move to the next distance can be determined according to the user's historical moving step data. For example, the historical data shows that the user moves 3 steps and walks one meter, and the user needs 1.5 steps to move to the next distance. meters, the user needs to take 1.5÷(1÷3) steps.

Further, the distance from the user to the test optotype in the test optotype display interface can also be calculated according to the size of the input device in the user's hand.

For example, the reference distance is 5 meters, and the non-reference distance includes 1 meter and 3 meters. The test vision of the user at 1 meter, 3 meters and 5 meters from the test target is obtained. If the user is at 1 meter and 3 meters from the test target , 5 meters, the test visual acuity is 4.1, 4.0, 4.0, then the test visual target size corresponding to the test visual acuity is the size of the visual target at the position of 4.1, 4.0, 4.0 in the eye chart.

S102. According to the size of the test optotype corresponding to the reference distance, determine the size of the healthy optotype corresponding to the user's non-reference distance.

Specifically, the size of the healthy optotype is calculated by the following formula.

Among them, y is the size of the healthy optotype, d ₁ is the reference distance, d ₂ is the non-reference distance, and s is the size of the test optotype.

Here, the user's healthy optotype size at other non-reference distances can be determined based on the user's test optotype size at the reference distance.

Meters correspond to the size of the healthy visual target, d ₁ is 5 meters, d ₂ is 1 meter or 3 meters, and s is the test visual target size corresponding to 5 meters.

S103. Determine the target distance from the non-reference distance by comparing the test optotype size and the healthy optotype size corresponding to the non-reference distance.

In the embodiment of the present application, by comparing the test optotype size obtained by the user at a non-reference distance with the user's theoretically healthy optotype size at a non-reference distance, it can be determined that the user's eyeball adjustment ability has begun to occur. Varying target distance.

Specifically, determine whether the test optotype size corresponding to the non-reference distance is the same as the healthy optotype size; if the test optotype size and the healthy optotype size corresponding to all non-reference distances are the same, then the longest distance among all non-reference distances Determined as the target distance; if the test target size and healthy target size corresponding to all non-reference distances are not the same, then determine the shortest distance among all non-reference distances as the target distance; otherwise, compare the minimum distance among non-reference distances The target distance is determined from the non-reference distance for the corresponding test and healthy optotype sizes.

Further, it is judged whether the test optotype size and the healthy optotype size of the minimum distance in the non-reference distance are the same; The longest distance among all non-reference distances with the same size as the healthy optotype is determined as the target distance; if the test optotype size and the healthy optotype size of the minimum distance in the non-reference distance are not the same, the test optotype size corresponding to the non-reference distance The shortest distance among all non-reference distances with the same size as the healthy optotype is determined as the target distance.

In the embodiment of the present application, if the size of the test optotype at the smallest distance in the non-reference distance is the same as the size of the healthy optotype, it can be determined that the user has no problem with short-distance vision and has problems with long-distance vision, so the user is a myopic patient. The user's target distance should be the longest distance among all non-reference distances for which the size of the test optotype corresponding to the non-reference distance is the same as that of the healthy optotype. If the size of the test optotype at the minimum distance in the non-reference distance is different from the size of the healthy optotype, it can be determined that the user has vision problems at short distances and no vision at long distances. Therefore, the user is a hyperopic patient, and the target distance of the user should be The test optotype corresponding to the non-reference distance is the shortest distance among all non-reference distances with the same size of the healthy optotype.

S104. Determine the axial deformation of the user's eye and/or the degree of hyperopia according to the target distance and the preset standard axial length of the eye.

Optionally, the axial deformation of the eye is calculated by the following formula.

Among them, α is the axial deformation of the eye, ν is the preset standard axial length of the eye, and u is the target distance.

Here, the preset standard axial length of the eye should be the axial length of most people under normal vision, and the greater the axial deformation of the eye, the higher the degree of myopia.

Optionally, the degree of hypermetropia is calculated by the following formula.

b=(u/w)(w+v)/(u+v).

Wherein, b is the degree of hyperopia, ν is the preset standard axial length of the eye, u is the target distance, and w is the preset hyperopia distance.

Here, the preset hyperopia distance is generally 20cm, and the larger the hyperopia parameter, the higher the degree of hyperopia.
