Abstract
The present invention proposes a two-eye adaptive optical visual perception training apparatus, comprising: left and right eye wave aberration measurement sub-systems for measuring eye wave aberrations of the left and right eyes of a person to be tested; left and right eye wave aberration correction sub-systems for driving and controlling the wavefront corrector to correct the wave aberrations of the left and right eyes of the person to be tested based on the measured wave aberrations of the left and right eyes of the tested person; and a two-eye visual perception training sub-system for processing and displaying sighting targets of different spatial frequencies and different contrasts and presenting the sighting targets to the tested person, to conduct a two-eye visual function measurement process and a visual perception training process. By means of the apparatus according to the present invention, finer visual stimulus is obtained by correcting aberrations of two eyes, and then eye acuity limit of the two eyes can be measured, and the visual perception training effect and visual function of the two eyes can be efficiently improved by performing visual perception training on the …
