ChromaGen™ and Colour Deficiency
Colour Vision deficiencies occur in 4-8% of males and 0.4-0.5% of females. At one point there really wasn’t much you could do about a red-green deficiency but not now….
Chromagen is a red contact lens worn in one eye by which the patient can compare different contrasts between the two eyes. The haploscopic filters work by changing the wavelength of each colour going into the eye.
Defective colour vision can range from near-normal ability to distinguish colours, where typically the chemical for seeing red or green is slightly altered, to a high degree of confusion.
In our years of fitting lenses, this one comes close to being the best one for the reaction people have when they realise all the colours they never knew existed.
