The Colour Blind Awareness organization has been founded to raise awareness of colour blindness (colour vision deficiency) and aims to be the first point of reference in the UK for people seeking information on colour blindness.
There are different causes of colour blindness. For the vast majority of people with deficient colour vision the condition is genetic and has been inherited from their mother, although some people become colour blind as a result of other diseases such as diabetes and multiple sclerosis or they acquire the condition over time due to the aging process, medication etc.
One of the main downfalls of being colour blind is that you will not be able to apply for certain jobs such as: pilot, police officer, fireman, painter and electrician to name a few.
