Color Blind

Friday, February 26, 2016

Color blindness is not a form of blindness at all, but a deficiency in the way you see color. Dr. Edward Hill tells us more about this condition in todays 60 Second Housecall.

Dr. Hill:

Many people think anyone labeled as color blind only sees black and white. This is actually very rare. The most common type of color vision problem is the red-green deficiency, where people cannot distinguish between red and green colors. The blue-yellow deficiency is also rare.

Color blindness is more common in men. It is estimated that 5 to 8 percent of males and less than 1 percent of females have color vision problems. Most color vision problems are hereditary and already present at birth. A color-defective male always inherits his deficiency from his mother, who usually has normal color vision.

Any child having difficulty in school should be checked for color vision deficiency. A person with a family history of color vision problems and anyone who has a job that requires identifying colors should be tested.

Unfortunately, there is no cure for hereditary color vision deficiency. Most people learn to adapt to color blindness. There are specially tinted eyeglasses that may help distinguish colors.
