Colour vision deficiency or colour blindness

Like many visual impairments, a colour vision deficiency is mostly inherited. Men are affected more often than women.

Colour vision deficiency or colour blindness? The two terms are often used synonymously. However, the hereditary visual impairments are not to the same at all. Protanomaly and deuteranomaly refer to a red or alternatively green weakness respectively. This means the colours can only be seen if they are very saturated and strong.

Colour blindness for different colours is referred to as anopia. With a protanope or alternatively deuteranope, the person is missing the colour receptors on the retina for the colour red and green respectively and the two colours are perceived as light shades of grey. Unfortunately, there are no possible therapies for colour vision deficiency or blindness. However, tinted lenses can ease the frequently occurring light sensitivity.
