At Zacks Eye Clinic in central London we see several patients with colour blindness, colour deficiency and symptoms of visual stress who benefit from ChromaGen tinted lenses.
What are ChromaGen Lens 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) whereby a specific colour tint can relieve visual stress and improve reading ability.
‘I am able to pass the colour blindness test with ChromaGen lenses. Highly Recommended’
ChromaGen Lenses for Colour Deficiency
In cases of colour deficiency, ChromaGen tinted lenses are used to change the distribution of coloured light entering into the non-dominant eye. In some cases, different lenses are used on 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 improvement to their colour vision with ChromaGen lenses. The lens tints enable 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. Improvement in colour discrimination may also lead to improved safety through earlier identification of hazards such as warning lights.
We would recommend that anybody who intends to use these lenses to pass occupational tests ensures that they are permitted by their professional bodies, assessors and employers.
ChromaGen Lenses for Visual Stress
ChromaGen lens tints can help some people who suffer from reading discomfort arising from perceptual distortion also known as visual stress. The most common symptoms of visual stress include words moving or sinking, shimmering or forming patterns that interfere with reading. Some people with visual stress may also have learning difficulties such as dyslexia.
When the optimal tint is selected, an immediate improvement in symptoms is experienced by responders who typically find the print becomes clearer and stays still on the page giving a marked improvement in reading speed.
