Colour Vision

Colour blindness is typically a genetic condition, and it is much more common in men than in women. Approximately one in 12 men has at least some colour perception problems.

Less common, acquired deficiencies stem from injury, disease, or the aging process. Also, although not called “colour blindness,” when people age, their corneas typically turn yellowish, severely hampering their ability to see violet and blue colours.
