Color blindness is not something that one can do to oneself intentionally. Colorblindness results from a defect within certain cells of the retina (part of the eyeball) or injury to the optic nerve, among other causes. Distortions in the cornea, the lens of the eyeball, (cataracts) also can cause partial color blindness.
