Abstract: Rectifying method for color blindness and the production method of rectifying eyeglasses for color blindness by using a computer to simulate the process of rectifying color blindness, improving the basic color, the color tone, and color saturation of the light entering the eye. In the rectifying of the color blindness, there are numerous kinds of spectrums and parameters of the rectifying eyeglasses for color blindness, which are then grouped under four types. The rectifying eyeglasses for color blindness change the proportion of stimulus of the three kinds of optic cone cells on the retina and alter the color codes of the visional area of the cerebral cortex, thus when the color blind viewer wears the properly chosen eyeglasses, the ability to discriminate between colors is greatly improved.
