Diagnosis of colour blindness
There are two main tests used to diagnose colour blindness:
• The Ishihara test – You’ll be asked to read the numbers on an image made up of lots of coloured dots.
• Colour arrangement – Various forms of this tests exist. They involve matching or arranging coloured objects or images in a book in order of their shades. Colour vision tests are not normally part of a routine eye exam, so please make sure you let us know when booking your appointment if you would like one.

Treating colour blindness
