Information on a range of common eye conditions and problems
This condition occurs more often in men, affecting around 1 in 20 in the UK. It is much less common in women, affecting only 1 in 200. Total colour-blindess (i.e. seeing only shades of grey), however, is extremely rare.
People are not always aware that they suffer from mild colour vision deficiency. We strongly recommend having your eyes tested by your optician at least every 2 years. If you have any concerns at all about your colour perception, make sure you ask for an eye examination that includes a test for colour vision.
There is no treatment for colour blindess. Sufferers generally have to adapt to the condition.
