Colour Blind Awareness

Colour blindness (also known as colour vision deficiency, or CVD) is thought to affect around 1 in 12 men (8%) and 1 in 200 women in the world. This means that in the UK there are approximately 2.7 million colour blind people (around 4.5% of the entire population), most of whom are male. This is due to the fact that the gene responsible for the condition is carried on the X chromosome.  There are different causes of colour blindness.

The Colour Blind Awareness organisation was founded to raise awareness of colour blindness and they aim to be the first point of reference for people seeking information on colour blindness in the UK.

The organisation provides support for colour blind people, especially colour blind children and their families and also their teachers. Any profits made by the organisation are used to provide free colour vision testing in schools and to provide educational supplies suitable for colour blind students.

Whether you’re a parent or a teacher dealing with CVD, the official Colour Blind Awareness website offers a wide range of information on understanding the condition which can cause many difficulties in everyday life which people without CVD are not aware of.
