Color Blindness
About Color Blindness
About 8% of men and 0.5% of women are color blind. John Dalton discovered it in himself and donated his eyes for study. Most common is red-green color blindness. Daltonism is still the term in some languages. There is no cure, but special lenses can help some types.
