说明书摘要	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.
