Color Blindness

By: Emily Landers

What is color blindness???

• Color blindness is condition where someone has a hard time distinguishing between certain colors, usually red, green or blue. It is usually an inherited condition. Color blindness occurs when there is a problem with the color-sensing pigments in certain nerve cells of the eye. These cells are called cones. They are found in the retina, the light-sensitive layer of tissue that lines the back of the eye. If just one pigment is missing, you may have trouble telling the difference between red and green. 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.

How do you get it?!?!

• Most color blindness is caused by passed on gene, usually from the mother. It can also be caused by damage to the eye, nerve, or brain.

Achromatopsia

• 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 severe light sensitivity, and extremely poor vision .Most color blindness is due to a genetic problem. About 1 in 10 men have some form of color blindness. Very few women are color blind. The drug hydroxycloroquine can also cause color blindness. It is used to treat rheumatoid arthritis, among other conditions
