Color blindness Color blindness is the inability to see some colors in the usual way. Color blindness occurs when there is a problem with the pigments in certain nerve cells of the eye that sense color. These cells are called cones. They are found in the light-sensitive layer of tissue at the back of the eye, called the retina.

Color Blindness This is the most common type of color blindness. If a different pigment is missing, you may have trouble seeing blue-yellow colors. People with blue-yellow color blindness usually have problems identifying reds and greens, too. The most severe form of color blindness is achromatopsia.A person with this rare condition cannot see any color, so they see everything in shades of gray. Achromatopsia is often associated with lazy eye, nystagmus (small, jerky eye movements), severe light sensitivity, and extremely poor vision.See: X-linked recessive) About 1 in 10 men have some form of color blindness. Very few women are color blind. The drug hydroxychloroquine (Plaquenil) can also cause color blindness. It is used to treat rheumatoid arthritis, among other conditions.

Types of Color Blindness Types of Color Blindness. Color blindness is a result of an abnormality in the eye’s photoreceptors called cones. A person who is color blind, or color deficient, has difficulty discerning between colors because of this. The human eye has three different types of cones that can be found in the retina: the L-cones, M-cones and S-cones. Each of these cones is sensitive to red, green and blue, respectively.
