A vision-testing method being applied to a vision-testing device, the vision-testing device comprising a light-transmitting apparatus, a plurality of vision test marks arranged on one side of said light-transmitting apparatus, and a plurality of light-emitting units arranged on another side of said light-transmitting apparatus for providing said vision test marks with a light source, wherein the plurality of vision test marks is arranged at multiple different subregions, and an arrangement of the vision test marks in each subregion comprises a plurality of rows or a plurality of columns; and in each subregion, the closer the row is to a center of the light-transmitting apparatus, the smaller the vision test marks corresponding to said row is; or the closer the column is to a center of the light-transmitting apparatus, the smaller the vision test marks corresponding to said column is, and wherein said method includes the following steps:
obtaining a vision test command;
controlling one of said light-emitting units to emit light according to said vision test command so as to highlight the corresponding vision test mark, wherein different vision test commands are configured to control light-emitting units at different positions to emit light, so as to highlight different vision test marks corresponding with the light-emitting units at different positions to display different patterns;
obtaining user-response information;
