Embodiment Construction

[0017] The present invention will be exemplarily described below based on a standard logarithmic vision chart using an "E"-shaped visual mark and related detection methods. It should be understood that the present invention is not limited to the specific shapes and detection methods described below, and the present invention is also applicable to other optotype shapes such as "C" and "J" shapes and related detection methods.

[0018] The eye chart used to test eyesight is designed according to the principle of visual angle, such as figure 1 As shown, the so-called angle of view is the angle formed by the light emitted by two external points and the node N in the eye.

[0019] The standard logarithmic eye chart stipulates that the angle of view formed by the minimum distance between two points can be distinguished by the human eye under standard vision, and the corresponding visual acuity is 5.0 (equivalent to 1.0 in the decimal recording method).

[0020] The conventional sta...

Abstract

The embodiment of the invention relates to a method, a device and a terminal for testing vision. The method comprises the following steps: acquiring position information of a tested person relative to a display screen for displaying optotypes; determining a display method of the optotypes based on the position information; displaying the optotypes on the display screen according to the display method; receiving a judgment result for the optotypes input by the tested person; and determining a vision testing result of the tested person based on the judgment result. With the adoption of the method, the device and the terminal for testing vision, a user can conveniently test the vision condition of the user without a special device, the special environment, a professional or the help of others, therefore, the vision testing process is simplified, and the intelligence level of vision testing is improved; and meanwhile, the functions of the terminal device are also enhanced.

Description

technical field [0001] Embodiments of the present invention mainly relate to a method, device and terminal for detecting eyesight. Background technique [0002] Eyesight is one of the important indicators that characterize people's physical condition, and it has a very important impact on people's production and life. Common visual acuity detection needs to carry out under the help of doctor, professional etc. with the help of eye chart. The specific detection principle and process are described in detail in "Standard Logarithmic Vision Chart (GB11533-2011)", for example. However, the above detection methods require special instruments and the help of others, and have high requirements for the detection environment, so there are many inconveniences. [0003] Out of concern for personal vision status, the inventor found in the process of realizing the invention that people expect to be able to measure their own vision conveniently and accurately without the help of professi...
