Colour Blindness Test

iOS iPhone

Do you know what colour blindness is?

Colour blind is the name given to people who do not have a 'normal' range of chromatic (color) contrast sensitivity. There are several different kinds of color blindness, and not all are due to genetic variations. The subjective experience of color vision is partially created by the retina measuring differences in the wavelengths of incident light.

Here is a series of tests (which include the Ishihara test) to check if you or your friends around you are colour blind.

** Strongly Adviced **

If you develop color vision problems when normally you have been able to see a full range of color, then you definitely should visit your doctor. Sudden or gradual loss of color vision can indicate any number of underlying health problems, such as cataracts.
