Wherein, the visual function detector is provided with a visual acuity testing module and a spatial contrast sensitivity testing module; the visual acuity testing module is used for detecting visual acuity; for example, the acuity testing module sets and outputs a single letter and a row letter, displays a video of the single letter and the row letter on the first display, and acquires user feedback, wherein the acquiring user feedback includes detecting eye, and/or pupil changes, and/or measurement results of a plurality of measuring electrodes, and the like, such as the current of the measuring electrodes and changes thereof; for example, the sharpness testing module may set and output a plurality of individual letters, wherein an individual letter includes both C and E letter forms, or, for example, the sharpness testing module may set and output a plurality of rows of letters, each row of letters including a single row of three letters, tested as a middle letter; the spatial contrast sensitivity testing module is used for detecting spatial contrast sensitivity, generally speaking, the spatial contrast sensitivity testing module has important practical value for early discovery of glaucoma, maculopathy, diabetic retinopathy and optic nerve diseases, and is helpful for evaluating the effect of excimer laser surgery.
