More than three million people in the UK are colour blind, meaning that they find it difficult to differentiate between certain colours and frequently misidentify colours. Spotting the symptoms of colour blindness in children can be tricky as even if they do suffer with its symptoms, they learn by association and ‘guess’ certain colours correctly.
For instance, if they learn that police lights are blue, when they see other items that are blue, they will identify them as blue too, even though they cannot see them as the ‘true blue’, they are.
Optometric Consultant at Contactlenses.co.uk John Dreyer has revealed the types of colour blindness and how to spot the unusual signs that you or your child is colourblind.
