Enchroma lenses and Colour deficiency:
It’s difficult to conceive how colour deficient people see the world compared to colour normal people. The eye contains three different pigments that absorb light form different parts of the rainbow. If all pigments are absorbing equal amounts of light, we see white or grey depending how bright the light is. If one of the pigments is absorbing more light than the others we see a colour.
In people with a colour vision deficiency, one of the 3 pigments doesn’t absorb light as well as the others, so a lot more light of that colour is needed to sense it as much as a normal colour sighted person. For example if you had a tin of white paint an added a small amount of green to it, a colour deficient person would have trouble noticing there has been any change at all.
Enchroma glasses can alter the amount of light falling on the 3 pigments in the eye, this allows for a different perception of the colour and brightness. These lenses allow people with colour deficiency to now discriminate colours where there is only a subtle difference in the colour qualities of the object.
Not only do Enchroma lenses make a person’s world more vivid, they are better able to perform the many colour coded tasks that exist in or world. Come and see us at our Australia Fair Practice for a free 5 minute assessment and trial of the Enchroma lenses.
