Learn About Color Blindness

Color blindness does not mean you are blind in any way. Color blindness actually means a person is unable to distinguish similar colors. This is usually blue and yellow or red and green. Color blindness is hereditary. It affects about 8% of men and less than 1% of females.

The most common color deficiency is red and green. A very small percentage of people who suffer from color blindness have trouble distinguishing blue and yellow. The blue-yellow color deficiency affects the same number of men and women in that small pool.

Color Blindness Explained

Many people are under the impression that a person who is color blind sees gray or black and white. This is never the case. Someone who is color blind will often see certain colors washed out or as previously discussed, they will have trouble distinguishing colors from one another.

If you find yourself having issues distinguishing colors after you’ve had normal vision all of your life, you should immediately see a doctor. This can be a sign of a major health problem such as cataracts. There are many tests that can be conducted to see the performance of your eyes.

Color blindness happens when light-sensitive cells in the retina fail to respond to wavelengths of light that allow us to see color. There are millions of cones in the retina that are responsible for our ability to see colors. In hereditary cases of color blindness, many of these cones are different than regular cones or there are cones missing, removing the ability to distinguish colors.
