__**HOW TO GET IT**__ __**SYMPTOMS**__
 * color blindness is a sex linked trait
 * it is a recessive trait that is inherited from your parents
 * this trait is an **X** linked trait, meaning a man only has to get one of the recessive genes on his **X** and he will have it, women will have to get the recessive gene on both of her **X** chromosomes
 * a more uncommon way to get color blindness is through disease
 * the diseases form cataracts,cloudy layers in the lends of your eyes,and are the most common ways to get color blindness besides inheriting it
 * varies between people
 * different people will see different shades of colors
 * less severe color blindness will result in you not being able to see the the difference between green or red, or blue or yellow, but can still see other colors normally
 * with severe color blindness, you cannot see color at all, you can only see shades of black, gray, and white
 * sometimes colors will blend together making it seem like a single color
 * __DIAGNOSIS__**
 * a doctor can look back at your family history too see if you may have color bliness
 * the American Optical/Hardy,Rand, and Ritter Pseudoissochromatic Test is the most common test doctors will perform to see if you have color blindness
 * This test consists of using an image with various colors and placing a character in the middle in dots of a colorblindness type.
 * The second test is the Ishihara test, which is almost exactly identical to the American Optical, except uses eight plates
 * The third test is the Titmus II Vision Tester Color Perception Test. This is known as the least accurate, and only tests for red-green colorblindness.
 * __Prognosis__**
 * in some cases of color blindness, the effects are only temporary
