At Zacks Eye Clinic in central London we see several patients who benefit from ChromaGen tinted lenses.
What are ChromaGen tints?
ChromaGen lens tints change the level of coloured light entering one or both eyes. They can be used to enhance colour perception and colour discrimination for people who are ‘colour blind‘ or to help with Meares-Irlen Syndrome (scotopic sensitivity syndrome) in dyslexia whereby a specific colour tint can improve reading ability.
ChromaGen for Colour Deficiency
In cases of colour deficiency, ChromaGen changes the level of each colour going into the non-dominant eye and, in some cases, both the dominant and non-dominant eye, enabling enhanced colour perception and colour discrimination between the two eyes.
In trials, most colour-blind people reported a significant enhancement to their colour vision with ChromaGen lenses. ChromaGen enables people with mild levels of colour deficiency to pass extremely sensitive tests such as the Ishihara test and can help those, with more severe colour deficiency to pass occupational tests that they would otherwise fail. Improved colour vision may also lead to improved safety through earlier identification of hazards such as warning lights.
ChromaGen for Dyslexia
ChromaGen tints can help approximately one in three people with reading discomfort arising from perceptual distortion. The most common symptoms of perceptual distortion include words moving or sinking, shimmering, pattern glare, and patterns formed by the spaces between words and lines that interfere with reading.
An immediate improvement in symptoms may be experienced after selecting the appropriate ChromaGen tint. Text typically becomes clearer and stays still on the page with an improvement in reading speed.
