The percentage of men who exhibit some sort of colorblindness is between 5% and 8%, and only about .4% of females. Usually, It is caused by a genetic mutiation in which the chromosomes are missing the genetic code for some of the cones in your optic nerve. Each cone has a different pigment sensitive to different kinds of light. In those that exhibit colorblindness the peak color wavelength is lower than someone with normal vision. The most common cause of colorblindness is from genetic inheritance, but it can also be caused by a disease involving the retina or the optic nerve, or due to damage to a part of the visual cortex in the brain. Some drugs have been known to cause colorblindness as well, such as hydroxychloroquine (Plaquenil), a drug used to treak patients with rheumatoid arthritis. Until now there is no cure for colorblindness.

Why does color blindness only occur in males?
Here is a simple explanation:Remember that all males have an XY and females have XX, colorblindness is on the X chromosome, and since it is passed on by the X chromosome, this means that females have one good X and one colorblind X . Since colorblindness is recessive, this means the good X can provide the necessary pigments and the female is not colorblind unless she receive two X's that have colorblindness (one from her mother and one from her father), highly unlikely.On the other hand, since the Y has very few genes on it, the pigment missing in the X carrying colorblindness would not be replaced and thus colorblindness would occur in males with the X colorblindness gene from the mother.More info on colorblindnessman pppl on here are smart i didn't know that!!!!! :)
