Colour Bilndness

[Rocketsnail]

I'm not sure if this is the place to ask this, but I know that as well as having inherited colour blindness, you can also acquire it. What I would like to know is if it's possible to become colour blind in one eye, not both?

Well, yes, there are people that are only blind in one eye, and having one affected doesn't necessarily mean the one will be as well. For instance, I see better with my right eye than with my left, and my contact lenses have different thickness, but if your case is hereditary, I'm not so sure.

Does colour blindness affect both eyes?
Answer

This depends on whether you have inherited or acquired colour blindness. If you have inherited colour blindness and you’re born with it, both eyes will be affected equally. However, acquired colour blindness may affect one or both eyes.
Explanation

Inherited colour blindness affects both eyes equally because it's passed down by a fault on a chromosome that controls the development of your cone cells. Chromosomes are structures that contain genes – these contain the instructions for life and are inherited from your parents.

Cone cells are light sensitive cells in your eyes, which allow you to see colour. Red-green colour blindness is passed down from parents on the X chromosome; blue colour blindness is passed down on chromosome seven (a non-sex chromosome).

You can develop problems with your colour vision as a result of an illness, a side-effect of a medicine and exposure to certain chemicals or a head injury, for example. This is called acquired colour blindness. This can affect each eye differently, for example if you have optic nerve disease it may be confined to one eye. Also, the condition may develop at different rates in each eye and cause differences in colour perception between your eyes. However, if you have good vision in both eyes, and are colour blind in just one, you should still be able to see colour well.

Marvellous, thanks the two you you.

I would have thought that if you acquire it you must have done some damage like looking at the sun for too long.
I'm colourblind but I inherited it.
