    What causes color vision deficiency?
    Most people who have color vision deficiency are born with it. This is because the most common types of color vision deficiency are genetic, meaning they’re passed down from parents.
    Color vision deficiency can also happen because of an injury to the retina (the light-sensitive layer of tissue in the back of the eye), t8he optic nerve (which connects the eye to the brain), or the brain itself. Some examples of injuries that can lead to color vision deficiency are:
    Retinal detachment (when the retina is pulled away from its normal position at the back of the eye)
    Eye injuries caused by lasers
    Some kinds of brain tumors - especially ones that affect the optic nerve or put pressure on the brain
    Radiation treatments
    Color vision may also get worse as you get older - often because of cataracts (cloudy areas in the lens of the eye).
