How Many People Are Colour-blind?
Color Blindness is more often than not an inherited condition, which causes the sufferer to be unable to distinguish certain colors. More numbers of people suffer from red/green color blindness, and statistics show that this form of color blindness aflicts about 99 percent of people with the condition. Another form of color blindness is blue/yellow, but this is quite uncommon, and there is no test available for it. Amazingly, color blindness occurs in about 8 to 12 percent of people of European origin, and affects only about one half of 1 percent of females. Complete color blindness, that is, a person being able to see only in shades of gray is very rare. There is no known cure for color blindness, although some sufferers are quite disabled and irritated by it. These people find that they cannot read weather forecasts, nor can they read traffic signals. Others just find it slightly irritating.
