Chapter 6: Frequently Asked Questions About Color Blindness


Q1/ Is there a cure for color blindness?
To answer that question we have to know first that color blindness is not a disease that can be cure by medicine. Color blindness is a congenital disease based in corrupted chromosomes which make the gene therapy the only way for treatment. Until now there is no cure. Some scientists are trying to find the cure and have done some successful experiments on monkeys but they still can't find any treatment for humans. For more details about the experiments, you can check chapter 3.

Q2/ Will my child inherit color blindness? 
Most of the cases, color blindness is caused by corrupted chromosomes that can be passed from the parents. The color gene is located in the X chromosome; so if the father is color blind he will not pass the corrupted chromosome to his sons, but all the daughter will be carriers. In the other hand, the mother has two X chromosomes. If the mother is a carrier (has the problem in only one of here Xs), the son will has 50% chance to has color blindness while the daughters will has 50% to be a carrier. However, if the mother is colorblind all the sons will have the disease while the daughters will be 100% carriers.

Q3/ Is there a solution for color blindness?
Yes, people with color blindness can see colors by the color correction glasses. Some companies had developed glasses that can help colorblind person to has better color vision. The glasses function is to pass colors that you has difficulty to see to your retina. However, the glasses will not make you see colors as a normal person and will not be useful for everyday life.

Q4/ Who should be tested for color blindness?
