Everyone sees colors differently. No matter if you are color blind or not. The retina in our eyes is made up of cones and rods. The cones are the part of the retina that control your color vision. The rods are the part that reacts to the light. When the pigments in the cones have a problem that is when it can result in you being color blind. So if there is only a few pigments that are damaged or missing then you will only have trouble seeing certain colors. When all pigments are missing than no color is seen at all.
Color blindness is when you have trouble seeing colors in a normal way, this can mean that you can see some colors well but have difficulty distinguishing between colors, or that colors are washed out or completely missing. There are more than three million cases of color blindness per year. It is extremely common in men and more rare in women. Color blindness is a genetic disease usually. It can be related to other medical conditions but the most common is from genetics. The most common genetic trend is from a Grandfather to Grandson having the mother be the carrier. About one in every twelve men are color blind.
Color blindness is usually identified when someone starts having trouble differentiating between colors. You can be tested at an eye doctor. Usually children are tested between ages 4-6 years of age, when they can verbalize what colors look like. Your ability to see color is developed when you are only six months old. Sometimes though color blindness can be so mild that you don’t even notice it and are never actually diagnosed. To be tested you would just need to make an appointment at an eye doctor. The doctor will show you circles made up of many different colors with a shape or number within the circle. The shape or number will not be able to be seen if you are color blind, but will be easily readable if you aren’t.

If you have a family history of color blindness in your family the chances of you having it or passing it along to your children is a lot higher. If you have glaucoma or age related macular degeneration also increases your chances of becoming color blind. Other medical conditions include, Alzheimers, multiple sclerosis, Kallman’s syndrome, Parkinson’s disease or diabetes. All of these have a side effect of color blindness. This does not mean you will for sure become color blind if you have one of these conditions, just means the chances of getting it is greater. Some anti-seizure medicines can cause color blindness as well as having damage to your optic nerve.
