Genetics;Mom gave it: Color blindness is not a disease;it is a genetic shift affecting 7% of males and 1/2 % of women. It is a variation in how one sees light browns, light greens and red/yellows.
Dr. David Chandler
Ophthalmology 33 years experience
Color blindness: About 8% of males and 1% of females are color blind. A more accurate description is color vision deficiency, as most people with this can see colors but may have trouble distinguishing hues. The most common is red-green color blindness, and people may confuse olives and tans. People with this would be able to distinguish traffic lights. There are many types of color vision deficiency.
