1. Color Blindness “Color blindness is the inability to see certain colors in the usual way.” By: Alex Murfree

2. Central vision is affected by a variety of eye diseases, this disorder is called Macular degeneration. What you see in front of you is central vision. Rather than your peripheral vision. Type of genetic disorder

3. Chromosome Graphic Mapping the human genome was started by colorblindness. In 1911, when red- green color blindness was assigned to the X chromosome. This was based upon the observation that color blindness is passed from mothers to their sons. So women are rarely affected. Men can not over come the defective chromosome, because they are carrying just one X chromosome.

4. Symptoms and effects Color blindness is not blindness, just a deficiency in the way one sees color. Blue and yellow; and red and green are harder to distinguish for those with color blindness. The red and green color deficiency is the most common. 10 percent of males and.5 percent of females in the U.S. have a vision deficiency. Primary signs of color blindness are if you have trouble deciphering the difference between blue and yellow, or red and green or have a family history of color blindness.

5. Diagnosis Color blindness is caused when there is a problem with the color- sensing materials or pigments in certain nerve cells of the eye. These cells are called cones. They are found in the retina, the light- sensitive layer of tissue at the back of the inner eye.

6. Prognosis Color blindness is inherited and is present in both eyes. It is continuous through a persons whole life. While some last for a short period of time. Most cases of color vision depravation aren’t severe and can be in one eye alone as well. Other cases tend to be progressive, becoming worse with time. Color blindness is a life-long condition. Most people are able to adjust without difficulty.

7. Treatment There is no cure for colorblindness. Gene therapy has cured colorblindness in monkeys, according to study results by researchers at the university of Washington and the university of Florida. Although these treatments look promising, they can not be done on humans until further testing proves safe.

8. Current Research On average about one child per class room of 20 has a mild color vision deficiency. Which can affect a child’s schoolwork and disqualify people from the job they desire. You can not be color blind and fly a plane. Not everyone will fly a plane or go into the police force, but we will all drive eventually. Distinguishing the color variations in traffic lights and signs can be a challenge for those who can not see red or green. RPB- supported institutions have been working on curing color blindness with gene therapy.

9. Genetic Counseling Genetic research has allowed medical professionals a much greater understanding on how inherited diseases and disorders are passed from generation to generation. One benefit of this information is the ability to receive genetic counseling to understand how such genes affect both you and your children.

10. 2 nd Graphic There are no physical differences for a person who is color blindness

11. Daniel Fluck living in Zurich Switzerland, a husband and father of two young children, works at a bank as an IT education professional. Daniel is red color blind, and could not find a lot of information on colorblindness so he made Colblindor in 2006 it has grown since then. He is not an eye doctor, just enjoys learning new things each day about his vision deficiency. Then writes them on his website to share with us.
