My best friend is color blind.  He does not see red or green
That would be so strange to be color blind. Can you tell me more about this disorder?
Males are more likely to be color blind than women, as the genes for the most common forms are on the X chromosone
Can people who are color blind see any colors at all or are they simply muted?
Some color blindness can have trouble seeing differences in color like red and green, while others cannot see any color at all
Wow! So there are some who completely see in only black and white? Is there any treatment available?
Gene therapy for color blindness
Gene therapy for color blindness is an experimental gene therapy aiming to convert congenitally colorblind individuals to trichromats by introducing a photopigment gene that they lack. Though partial color blindness is considered only a mild disability and is controversial whether it is even a disorder, it is a condition that affects many people, particularly males. Complete color blindness, or achromatopsia, is very rare but more severe. While never demonstrated in humans, animal studies have shown that it is possible to confer color vision by injecting a
blindness is an inherited problem in the development of one or more of the three sets of color-sensing cones in the eye. Males are more likely to be color blind than females, as the genes responsible for the most common forms of color blindness are on the X chromosome. As females have two X chromosomes, a defect in one is typically compensated for by the other, while males only have one X chromosome. Color blindness can also result from physical or chemical damage to the eye, optic nerve or parts of
