What is colour blindness? Colour (color) blindness (colour vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women. In the UK there are approximately 3 million colour blind people (about 4.5% of the entire population), most of whom are male.

Worldwide, there are estimated to be about 300 million people with colour blindness, almost the same number of people as the entire population of the USA! There are different causes of colour blindness. For most colour blind people their condition is genetic, usually inherited from their mother, although some people become colour blind as a result of other diseases such as diabetes and multiple sclerosis or it can be acquired due to ageing or from taking drugs and medications.
