ABSTRACT:
Rectifying method for color blindness and rectifying eyeglasses for color blindness by using a computer to simulate the process of rectifying color blindness, there are produced 32 kinds of spectrums and parameters of rectifying eyeglasses for color blindness, which are then grouped under four types. The rectifying eyeglasses for color blindness change the proportion of stimulus of three kinds of optic cone cells on the retina and alter the color codes of the visional area of cerebral cortex, thus when a color-blind viewer wears the eyeglasses chosen properly, the ability of discrimination between different colored objects is greatly improved.
