Cutting edge lenses for colour blindness
19th February 2013
An American research institute 2AI Labs believes to have discovered lenses that can be used for colour blinded people to see the full spectrum of colours. Colour blinded people are usually unable to perceive some of the red and green colours, for which the lenses are designed to help. So called red-green deficiency could help up to 10% of male population and a small percentage of females who suffer from some form of red-green colour blindness. The lenses were originally developed for medical purposes, to enable nurses and doctors seeing veins and bruises more clearly. However, the scientists realized that they can also be used for the public, and are already available on the US market. Wearing them could even enable their wearers to pass a test for colour blindness, known as Ishinara Colour Test, where patients need to identify numbers in the circle of dots. The only disadvantage is that they reduce the ability see yellow and blue colours.
