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?
They are experimenting with gene therapy to try and help individuals by introducing a photopigment gene
Oh that is great news! Have they had any success with treatment?
