Color Blindness

Source:allaboutvision

Color blindness is not a form of blindness at all, but a deficiency in the way you see color. With this vision problem, you have difficulty distinguishing certain colors, such as blue and yellow or red and green.

Color blindness (or, more accurately, color vision deficiency) is an inherited condition that affects males more frequently than females. According to Prevent Blindness America, an estimated 8 percent of males and less than 1 percent of females have color vision problems.

Red-green color deficiency is the most common form of color blindness.

Much more rarely, a person may inherit a trait that reduces the ability to see blue and yellow hues. This blue-yellow color deficiency usually affects men and women equally.
