Color Blindness
Color Blindness, or Color Vision Defenciency, is genetic. It can also be caused by brain, nerve, eye damage, or if you are exposed to certain chemicals. Color vision genes are in the X chromosome. This makes it more common in males because they only have one.
There are many different colors that color blind people can't see. there is green, yellow-green, yellow, blue, violet, red, and some can't see any color at all.
Inherited color blindness can be congenital (from birth), or can occur during chilhood or adulthood. another cause of color blindness can be damage of the retina caused by Shaken Baby syndrome.
