The system further comprises running a registration/login module before the optotype size confirmation module,
in the registration/login module, judging whether the user is subjected to initial test or not according to a user identifier carried in a training request sent by a client, if the user is subjected to initial test, starting the test from an initial position, and if the user is not subjected to initial test, determining the initial test position of the user according to a last test result;
the system further includes running the data storage module after the test module,
and in the data storage module, storing the generated test result in a terminal and/or transmitting the test result to a server for storage.
9. The system of any one of claims 7 to 8, wherein the optotype display module comprises:
visual target size judging module: the system comprises a screen resolution ratio acquisition module, an image generation module and a visual target size adjustment module, wherein the screen resolution ratio acquisition module is used for acquiring the screen resolution ratio of a terminal screen, judging whether the visual target size is in a set interval range according to the screen resolution ratio, if so, operating the image generation module, and otherwise, operating the visual target size adjustment module;
an image generation module: the visual target is used for generating and displaying visual targets in random directions;
visual target size adjustment module: if the size of the sighting target is larger than the maximum set value, reducing the size of the current sighting target, and then returning to the execution sighting target size judgment module; if the size of the sighting target is smaller than the minimum set value, the current sighting target size is enlarged, and then the sighting target size judging module is returned to be executed.
10. A computer-readable storage medium, characterized in that the computer-readable storage medium stores a computer program configured to, when invoked by a processor, implement the steps of the method of any of claims 1-6.
