What is color blindness

Color blindness: Color blindness is the inability to see certain colors adequately. This is an inherited condition (x-linked recessive) that affects men much more than women. The defect is in the retina and involves a problem with color sense in pigment granules. The commonest affect is trouble distinguishing red from green. See your doctor for an examination and proper treatment.

Color difficulty: This is (usually) an inherited inability to distinguish between certain colors. The color receptors in the eye's film layer (retina) do not have the appropriate pigment, making it impossible to tell the difference between some colors, such ase blue vs. Green or re vs. Green. Color blind patients are not blind, and can use cues (position of lights in a stop light, etc.) to make up for this loss.

Unable to see colors: People who are colorblind are unable to distinguish between certain colors. Most commonly it affects only certain colors, such as green and brown, but in some people other colors are also affected.

Color blindness: Color blindness is a congenital or acquired condition whereby a person cannot see certain colors well because the parts of the eye that receive those wavelengths of light do not function well. For example, some people are born with red=green color blindness. They cannot see the color red or green well. Those colors would look gray or "washed out". Special tests can determine color blindness.
