Colour Blindness

What is Colour Blindness?

Colour blindness (colour vision deficiency) is the decreased ability to see colour or differences in colour.

The most common cause of colour blindness is an inherited problem in the development of one or more of the three sets of the eyes' cone cells, which sense colour.

Diagnosis is typically with the Ishihara colour test; other methods include genetic testing. There is no cure for colour blindness.
