Color+Blindness

**Color Blindness A.K.A Acromatopsia** __Type of Genetic Disorder__ Color Blindness is a sex-linked disorder, found on the X chromosome and is recessive. Men are more likely to inherit this trait because they only have one X chromosome, and if that chromosome has it then they become colorblind. Women are less likely to have color blindness because they need two X chromosomes to contain the recessive gene. Color blindness can also be caused by aging or injury to the eyes.

Color Blindness is most common in the form of Red/Green color blindness. This occurs in 99% of the cases, and it makes distinguishing red and green colors difficult. Also, a Blue/Yellow color blindness is possible, but highly uncommon.

__Diagnosis and Prognosis__ Doctors can simply check to see if you have trouble seeing certain colors to diagnose if you have color blindness. This can be done during an eye exam. Color blindness is a life-long condition, and most people can live without difficulty. [] This is an example of a test someone can take to see if they have red/green color blindness. Those who are colorblind won't be able to see the green 15.

Color blindness that is inherited at birth can not be treated. Although color blindness that occurs say from cataracts, or old age can be improved over time, but that is not always the case.

__Statistics__ Color blindness affects about 13 out of 1000 people. In the United States, 8% of men have colorblindness, while only 0.4% of women have it. [] These are several different tests for color blindness. [] Most color blindness effects the cones of the eye as you can see in this picture.

Some famous people with color blindness are Samuel Clemens, Mr. Rogers, John Dalton, and Paul Newman. __Bibliography__ [] [] [] www.iamcal.com/toys/**color**s/stats.php - 4k
