Dyschromatopsia : what could this be ?

This seemingly barbaric word simply means a disorder of colour vision. It affects mainly men : 8 % as compared to 0,5 % of women. It consists in not seeing certain colours. Among them : red (it is then called colour-blindness), green or blue. In some cases dyschromatopsia is a hereditary disorder. There is no way of correcting the vision of colours. One learns to cope with it !
