A visual acuity detection method based on a motion visual evoked potential, comprising: first designing a concentric ring stimulation paradigm, then designing a stimulation paradigm spatial frequency gradient, then performing building of a brain-computer interface platform and presentation of the stimulation paradigm, performing visual acuity threshold determination on a electroencephalogram result, finally, performing feedback of a visual acuity detection result. According to the method, a concentric ring steady-state motion visual evoked potential (SSMVEP) paradigm for visual acuity examination is designed, and corresponding threshold determining standards are proposed, so that an electroencephalogram objective visual acuity value is obtained. An objective and quantitative measurement method is provided for visual acuity detection in ophthalmologic examination.
