Who's Color Blind & Why

Condition more likely to affect boys.
A  study of more than 4,000 California preschoolers finds color blindness mostly affects Caucasian boys with one in 20, affected by the condition.
 
"The problem in color vision deficiency is on the X chromosome. Girls have 2  X's, boys have 1 X. If a boy gets a bad X he doesn't have another X, so he's going to be affected," explains Dr. Miesha Frempong, Mount Sinai Hospital.
 
The most common form of color blindness is genetic. People lack the genes that help the eye see red or green. There is no reversal or cure for the inherited form of color blindness.
