Can defective colour vision be corrected?
Most people who have poor colour vision are born with the condition (it is congenital). It is hereditary and mainly affects males. There is no cure for congenital colour defects, but some people find it useful to have special tinted spectacles or contact lenses where the tint in one eye is different from that in the other. Although this does not restore the appearance of colours it may enable you to be able to distinguish between certain colours more easily by comparing the appearance of the colour through one eye with that through the other. However, this will not enable you to get a job which is not open to those with defective colour vision.
