Default Can You "Become" Color Blind?

Is color blindness something you're just born with, or can you gradually lose your ability to perceive color over time as an adult?

I believe that it is an inherited condition for the most part, that's why they give the tests to children.

I know it's an inherited trait, and it only happens in boys, because the gene is carried on the Y chromosome. I think it can happen to girls under certain circumstances, like maybe some kind of accident. In that case I think a boy or a girl could become color blind, but I don't know, that's why I posted the question in the first place.

Yes, color blindness is genetic, but I think that it's a little like hemophilia. If a female can't get color blindness, then there's still a possibility that they could become a carrier for that genetic trait.

There's another post in here about color blindness and it explains how it's possible for a girl to be color blind:

I think if a person were ever to just suddenly become color blind, then it would have to be a warning sign of a very serious medical condition. I'd believe it if becoming color blind were a side effect of some medicine. It would probably just be temporary, though.

Default Acquired Color Blindness

Here's what I found in Wikipedia: "Acquired color blindness is generally unlike the more typical genetic disorders. For example, it is possible to acquire color blindness only in a portion of the visual field but maintain normal color vision elsewhere. Some forms of acquired color blindness are reversible. Transient color blindness also occurs (very rarely) in the aura of some migraine sufferers."

Thanks Sk8terboi. That stuff sounds really weird. Imagine only seeing colors one side or something. Then imagine suddenly being able to see colors after seeing in black and white all your life.

I know this thread is a few years old but I came by with the same question. Having read this I have to mention...

The color-blind gene is on the X chromosome; the Y has no genes for vision. The reason males are so much more likely to get it (8% to women's 1%) is that we only have one X chromosome, so only that one needs to have the recessive gene. Women have two, and both would require it for the effect, hence being recessive (genes only active in the absence of a dominant gene).

Also, in case someone else comes by wondering about acquired color-blindness, I found some things. It can be caused by ultraviolet light damage to the retina, damage to the occipital lobe (the part of the brain responsible for sight), degenerative eye diseases, retinal damage from diabetes and a Vitamin A deficiency.

Fun fact, color is a construct of the mind. The eye responds to three wavelengths of visible light, long, medium and short (red, green and blue respectively) then sends an electrical signal based on the intensity of each, which the brain decodes as color. Before color-sighted animals, color just didn't exist.

Interesting, yea?

Most color vision problems are inherited and are present at birth. Approximately 1 out of 12 males and 1 out of 20 women are color blind.
