A method for determining a visual capacity of a user, comprising: step 1, presenting one or more groups of visual stimulation streams; step 2, collecting electroencephalography information produced by attentional or inattentional vision, wherein the electroencephalography information comprises an electroencephalogram and a brain area corresponding thereto; step 3, grouping the visual stimulation streams and corresponding electroencephalograms by time; and step 4, determining the user's visual capability according to the electroencephalograms of the user. By means of the method, objective detection of a visual function can be performed on a tested person who is inattentional, who cannot fix on visual information and who cannot actively cooperate.
