Human eye adaptive optical visual perception training method and apparatus thereof
First Claim
1. A human eye adaptive optical visual perception training method, comprising the step of:
- a human eye wave aberration measurement step for measuring the human eye wave aberration of a person to be tested by using a near infrared reference light source, a wavefront corrector and a wavefront sensor;
a human eye wave aberration correction step for driving and controlling the wavefront corrector to correct the human eye wave aberration of the person to be tested based on the measured human eye wave aberration of the tested person; and
a visual perception training step for displaying on a sighting target display sighting targets of different spatial frequencies and different contrasts after they have been subjected to processing in a video processing circuit, and presenting the sighting targets to the tested person via the driven and controlled wavefront corrector, to conduct a human eye visual function measurement process and a visual perception training process,wherein the video processing circuit combines the R channel and the B channel from a normal video output and obtains a grayscale of or higher than 14 bits.

Abstract
The present invention proposes a human eye adaptive optical visual perception training apparatus, comprising: a human eye wave aberration measurement sub-system for measuring the human eye wave aberration of a person to be tested; a human eye wave aberration correction sub-system for driving and controlling the wavefront corrector to correct the human eye wave aberration of the person to be tested based on the measured human eye wave aberration of the tested person; and a 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 human eye visual function measurement process and a visual perception training process. The apparatus according to the present invention is capable of several functions including eye aberration correction, visual function measurement, visual perception training. Finer visual stimulus is obtained by correcting human eye aberration, and then the human eye acuity limit can be measured, and the visual perception training effect and visual function of the human eye can be efficiently improved by performing visual perception training with such apparatus.
