It will be apparent to those skilled in the art that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Although the present application is described primarily in the context of "vision testing," it should be understood that this is merely one exemplary embodiment.
It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
The following describes a method for detecting eyesight provided in the embodiments of the present application in detail.
Referring to fig. 1, a schematic flow chart of a vision testing method provided in the embodiment of the present application is shown, and exemplary steps in the embodiment of the present application are described below:
s101, obtaining test eyesight of a user at different distances from a test visual target and test visual target sizes corresponding to the test eyesight.
In the embodiment of the application, the distance comprises a reference distance and a non-reference distance, and the test vision corresponding to the test vision and the test vision size corresponding to the test vision of the user at the reference distance and the non-reference distance from the test vision are obtained. Here, the obtained test eyesight of the user at the reference distance and the non-reference distance from the test optotype and the test optotype size corresponding to the test eyesight are the test eyesight of the user at the reference distance and the non-reference distance and the test optotype size corresponding to the test eyesight.
The reference distance is only one, and the non-reference distances may be multiple.
Specifically, a test sighting target display interface corresponding to a user is displayed in the human-computer interaction display equipment; aiming at a test sighting target display interface, receiving a sighting target direction input by a user through input equipment at different distances from a test sighting target; and determining the test eyesight of the user respectively corresponding to the test eyesight under different distances from the test eyesight and the test eyesight target size corresponding to the test eyesight according to the eyesight target direction input by the user and the real eyesight target direction of the test eyesight target.
The input device may be a remote controller, an app in a mobile phone, a wireless keyboard, or the like.
Here, a plurality of test sighting target display interfaces are displayed simultaneously on the human-computer interaction display device, and each test sighting target display interface performs vision detection for one user, that is to say, the vision detection can be performed for a plurality of users simultaneously. When the vision of a user is detected, the user stands at a specified distance of a test visual target display interface corresponding to the user, the test visual target display interface sequentially displays test visual targets with various sizes, the user inputs the direction of the test visual target aiming at the test visual target with each size displayed on the test visual target display interface, and the test vision of the user at the specified distance and the test visual target size corresponding to the test vision are obtained according to the visual target direction input by the user and the real visual target direction of the test visual target. The user then performs the test again moving to the next distance.
Further, the number of steps the user needs to move to the next distance can be determined from the historical movement step data of the user, for example, if the historical data shows that the user moves 3 meters and 1.5/1/3 steps.
Further, the distance from the user to the test optotype in the test optotype display interface can be calculated according to the size of the input device in the hand of the user.
For example, the reference distance is 5 meters, the non-reference distance includes 1 meter and 3 meters, the test eyesight of the user at positions 1 meter, 3 meters and 5 meters from the test optotype is obtained, and if the test eyesight of the user at positions 1 meter, 3 meters and 5 meters from the test optotype is 4.1, 4.0 and 4.0, the test optotype size corresponding to the test eyesight is the size of the optotype at the position of 4.1, 4.0 and 4.0 in the visual chart.
And S102, determining the corresponding health sighting target size of the user under the non-reference distance according to the test sighting target size corresponding to the reference distance.
Specifically, the healthy optotype size is calculated by the following formula.
Wherein y is the size of the health sighting mark, d 1 Is a reference distance, d 2 Is the non-reference distance and s is the test optotype size.
Here, the theoretical healthy optotype size of the user at other non-reference distances is determined by the test optotype size of the user at the reference distance.
For example, the reference distance is 5 meters, the non-reference distance includes 1 meter and 3 meters, the health sighting target size corresponding to 1 meter and 3 meters of the user is determined according to the test sighting target size corresponding to 5 meters, y is the health sighting target size corresponding to 1 meter or 3 meters, and d 1 Is 5 m, d 2 Is 1 meter or 3 meters, and s is the test sighting mark size corresponding to 5 meters.
S103, determining the target distance from the non-reference distance by comparing the test sighting target size and the health sighting target size corresponding to the non-reference distance.
In the embodiment of the application, the target distance at which the eyeball adjustment force of the user starts to change can be determined by comparing the size of the test sighting mark obtained by testing the user at the non-reference distance with the theoretical size of the healthy sighting mark of the user at the non-reference distance.
Specifically, judging whether the test sighting target size corresponding to the non-reference distance is the same as the health sighting target size; if the test sighting target size and the health sighting target size corresponding to all the non-reference distances are the same, determining the longest distance in all the non-reference distances as a target distance; if the test sighting target size and the healthy sighting target size corresponding to all the non-reference distances are different, determining the shortest distance in all the non-reference distances as a target distance; otherwise, the target distance is determined from the non-reference distance by comparing the test visual target size and the healthy visual target size corresponding to the minimum distance in the non-reference distances.
Further, judging whether the size of the test sighting mark of the minimum distance in the non-reference distances is the same as that of the health sighting mark; if the test sighting target size of the minimum distance in the non-reference distances is the same as the healthy sighting target size, determining the longest distance in all non-reference distances corresponding to the non-reference distances, wherein the test sighting target size is the same as the healthy sighting target size, as the target distance; and if the test sighting target size of the minimum distance in the non-reference distances is different from the health sighting target size, determining the shortest distance in all the non-reference distances, which are the same as the test sighting target size and the health sighting target size, corresponding to the non-reference distances as the target distance.
In the embodiment of the application, if the test sighting target size of the minimum distance in the non-reference distances is the same as the healthy sighting target size, it can be determined that the user has no problem in the short-distance vision and has a problem in the long-distance vision, so that the user is a myope, and the target distance of the user is the longest distance in all non-reference distances in which the test sighting target size corresponding to the non-reference distance is the same as the healthy sighting target size. If the test sighting mark size of the minimum distance in the non-reference distances is different from the healthy sighting mark size, the fact that the vision of the user at the short distance is problematic and the vision at the long distance is not problematic can be determined, so that the user is a hypermetropic patient, and the target distance of the user is the shortest distance in all non-reference distances, wherein the test sighting mark size corresponding to the non-reference distances is the same as the healthy sighting mark size.
And S104, determining the deformation amount of the eye axis and/or the far vision degree of the user according to the target distance and the preset standard eye axis length.
Alternatively, the amount of eye axis deformation is calculated by the following formula.
Wherein alpha is an eye axis deformation quantity, ν is a preset standard eye axis length, and u is a target distance.
Here, the preset standard eye axis length should be the eye axis length of most people under normal vision, and the larger the eye axis deformation amount is, the higher the myopia degree is.
Alternatively, the degree of hyperopia is calculated by the following formula.
b＝(u/w)(w+v)/(u+v)。
Wherein b is the far vision degree, ν is the preset standard axial length, u is the target distance, and w is the preset far vision distance.
Here, the preset distance is generally 20cm, and the higher the distance parameter is, the higher the distance is.
The embodiment of the application provides a vision detection method, which comprises the following steps: acquiring test eyesight of a user at different distances from a test visual target and a test visual target size corresponding to the test eyesight; the distance comprises a reference distance and a non-reference distance; determining the corresponding health sighting target size of the user under the non-reference distance according to the test sighting target size corresponding to the reference distance; determining a target distance from the non-reference distance by comparing the test sighting mark size and the health sighting mark size corresponding to the non-reference distance; and determining the eye axis deformation amount of the user according to the target distance and the preset standard eye axis length. According to the method and the device, the target distance is determined through the corresponding test sighting mark size under the non-reference distance and the corresponding health sighting mark size under the non-reference distance determined according to the test sighting mark size corresponding to the reference distance, then the axial deformation amount and/or the far vision degree of the user are determined according to the target distance and the preset standard axial length, the vision detection is accurate and efficient, and the axial deformation amount and/or the far vision degree of the user can be accurately determined.
Referring to fig. 2, which is a schematic flow chart of another vision testing method provided in the embodiment of the present application, steps S202 and S203 refer to S102 and S103 in fig. 1, which are not described herein again, and exemplary steps in the embodiment of the present application are described below:
s201, under different eye using time lengths, corresponding test eyesight of a user at different distances from a test eyesight target and a first eyesight target size corresponding to the test eyesight are obtained.
Wherein the distance comprises a reference distance and a non-reference distance.
Specifically, the historical target distance corresponding to the user is determined, and the test eyesight corresponding to the user within the historical target distance and at different distances from the test sighting target under different eye using durations is obtained.
In the embodiment of the application, the historical target distance obtained when the user tests the eyesight in the past is determined, and the corresponding test eyesight of the user within the historical target distance and at different distances from the test sighting target under different eye using time lengths is obtained.
Here, the historical target distance of the user, that is, the distance at which the user's eye-adjusting power starts to change, and therefore, the factor that affects the user's eyesight within the historical target distance is necessarily the length of time spent on eyes.
For example, if the historical target distance is 4 meters, then all non-reference distances are less than 4 meters.
S202, aiming at each eye duration, determining a second visual target size corresponding to the user at the non-reference distance under the eye duration according to the first visual target size corresponding to the reference distance.
S203, determining the corresponding target distance under the eye use duration by comparing the corresponding first visual target size and the corresponding second visual target size under the non-reference distance.
And S204, determining the optimal eye using time length of the user according to the corresponding target distances under all the eye using time lengths.
Specifically, all the eye-using durations are arranged from small to large, and the eye-using duration in which the target distance corresponding to the eye-using duration changes first is determined as the optimal eye-using duration of the user.
For example, the eye-using time is 5 minutes, 10 minutes, 20 minutes, 30 minutes, the target distances corresponding to the eye-using time are 4 meters, 3 meters, 2 meters, the eye-using time in which the target distance corresponding to the eye-using time changes first is 20 minutes, and the optimal eye-using time of the user is determined to be 20 minutes.

By the method and the device, the optimal eye use time of the user can be determined.

s301, under different environment brightness, the test eyesight of the user corresponding to the test optotypes at different distances from the test optotypes and the first optotype size corresponding to the eyesight are obtained.
Wherein the distance comprises a reference distance and a non-reference distance.
Specifically, the historical target distance corresponding to the user is determined, and the test eyesight corresponding to the user within the historical target distance and at different distances from the test sighting target under different ambient brightness is obtained.
In the embodiment of the application, the historical target distance obtained when the user tests the eyesight in the past is determined, and the corresponding test eyesight of the user within the historical target distance and at different distances from the test sighting target under different environmental brightness is obtained.
Here, the historical target distance of the user, that is, the distance at which the user's eye-adjusting power starts to change, and therefore, the factor that affects the user's eyesight within the historical target distance is necessarily the ambient brightness.
S302, aiming at each environment brightness, according to the first visual target size corresponding to the reference distance, determining a second visual target size corresponding to the user at the non-reference distance under the environment brightness.
And S303, determining the corresponding target distance under the ambient brightness by comparing the corresponding first visual target size and the second visual target size under the non-reference distance.

Specifically, all the ambient luminances are arranged from small to large, and the ambient luminance in which the target distance corresponding to the ambient luminance is changed first is determined as the optimal ambient luminance of the user.
