What is the colour vision test?

The Ishihara colour vision test is the most commonly used method for detecting red-green colour blindness (colour vision deficiency). The test was developed by Japanese ophthalmologist Dr. Shinobu Ishihara in 1917.

The test consists of coloured plates containing dots of various colours and sizes. People with normal colour vision can recognise numbers or shapes hidden in these plates, whilst people with colour vision deficiencies cannot see them or see different patterns.
