 * Color Blindness **

**Description: ** A person with color blindness has trouble seeing red, green, blue, or mixes of these colors. It happens when you don’t have certain cone cells or they don’t work in the eye. Aging eye problems, injury to the eye and side effects from medicine can lead to this. It occurs when there is a problem with the color seeing materials (pigment) in certain nerve cells in the optic nerve or retina.

**Inheritance: ** Mostly men are more likely to be color blind. The gene for this trait is located in the X – Chromosome. Women have two X – Chromosomes and men have one X and one Y chromosome. If a man inherits the gene, he will have a color vision defect. A woman must inherit the defective trait from both parents to have a color vision defect.

**Symptoms: ** If you have color blindness, you will not know that you see certain colors differently until someone else tells you. Usually your teacher or parents will notice that at a young age you will be color the face of a person the wrong color. You only see a few shades of colors. In rare conditions you will only see black, white, and gray. You will have trouble with naming color on something. You also won’t be able to group thing by color. In severe cases, you will have side to side eye movements.

**Diagnosis: ** Color blindness is usually diagnosed by simply tests. You may have to look at sets of colored dots and try to find a pattern, such as a letter of number. The patterns you see will help the doctor determine which colors you have trouble seeing. You will also have to arrange colored chips in order to how similar colors are to you. People with color blindness can’t arrange them correctly. Another test is looking at colored charts called Ishihara test plates.

**Treatment: ** Inherited color blindness cannot be treated. Acquired can be treated sometimes. Surgery to remove the cataract may restore normal vision. Wearing colored contact lenses will also help. You can wear glasses that block any glare too.

**Research: ** Gene therapy may cure color blindness. There is no real way color blindness can be cured. Eye exams and prompt treatment of the eye might help prevent some cases of color blindness.
