A customizing equipment for individualized contact lenses comprises an uniform illumination system, a gray image generation system, a projection optical system, a stage system and an alignment system, among which the uniform illumination system generates uniform parallel illuminative light, which generates gray images through the gray image generator controlled by a computer after going through the gray image generation system according to detection results of aberration of human eyes, and images on the image plane of given radius of curvature with photoresist on the samples' surface, which is fixed on the stage system and adjusted to the correct position through the alignment system, after the gray images are zoomed and the curvature of the image field is corrected through the projection optical system, so that the photoresist on the samples' surface will be exposed according to the gray levels of the gray images, after which the exposed samples are developed and etched to obtain the device with continuous embossment microstructure on the sphere. After the checking and post-processing, this device will result in the individualized contact lenses, which can be worn. This current invention can realizes fast customization of individualized contact lenses.

Customizing equipment for individualized contact lenses

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.
