Question for my colorblind brothas. Is there a lasic style surgery for us as well? Is color blindness a change in the brain DNA, or the eyeball itself?

I'm not colorblind, but I know the answer (dad was mildly colorblind). It's genetic. Men suffer it more than women because it's carried on the X chromosome. Since guys have one X and women have two, women have a much smaller chance of having two defective X's so they suffer from this considerably less. Surgery can't help.

Least ways, this is true of common colorblindness. Perhaps there are unusual alternative ways to have this problem.

I used to have to do a long set of colorblindness tests every couple years. Two of the ~20 plates I had trouble with. I could tell there was something there and ultimately I figured it out but kinda had to study and squint. Nurse giving the test always said they were all blatantly obvious to her, but a large fraction of guys struggled or simply failed to get the couple charts I had trouble with. Don't recall exactly the number but I think she said you could miss 3 or 4 and still pass the FAA medical exam.

This is called Color Weak, my brother has that. Yes its genetic, but that doesn't mean its not correctable. if its a brain deficiency then obviously it probably wont be a solution in our lifetime, but if the genetic deficiency is in the eye there might be a solution some day.
