Colour Blindness



Colour blindness relates to an individual’s ability to detect or perceive certain colours. The most common colours that colour blind people tend to have difficulty detecting include reds, greens, yellows, blues and oranges. This condition is often hereditary and is far more common in men than in women. Some people may also develop colour blindness as a result of diabetes, multiple sclerosis or through the natural aging process.


Those that have a colour deficiency are sometimes unaware that they perceive colours differently to the rest of the population. Often in the case of children that are born with this condition they may have been conditioned at an early age to identify that an apple is red, grass is green and the sky is blue. Unfortunately they grow up having no concept of true colours until diagnosed by a professional. To test for colour vision deficiency we recommend booking an eye test with your local Optometrist. The most common method used to test for colour vision deficiency is the Ishihara Plate Test, first introduced by Dr Shinobu Ishihara from the University of Tokyo in 1917.


If you have any doubts or queries regarding colour vision deficiency we would love to assist you at either of our Optical World stores. Our Eye Tests are still Bulk-Billed at Optical World and we offer free eye health checks to all our customers.
