Treatment of Colour vision deficiency

There is currently no cure for colour vision deficiency but those affected can be taught to adapt to their inability to distinguish colours. For example, adults may drive safely once they know the different positions of traffic signals (rather than relying on colours).

Tinted contact lenses are sometimes worn in one eye, to enhance contrast, but this can inhibit the ability for depth perception. People with colour vision deficiency, especially children, may need help in picking out clothing and other coloured items.

If colour blindness has been caused by another eye condition or other chronic illness, it is may be improved by treating that condition. It is therefore important to seek medical advice to determine which type of colour vision deficiency is present.
