Chromagen lenses

If you have found Coloured Overlays to be helpful for reading then Chromagen™ can probably help you.

Did you know that many extremely successful people are (or were) dyslexic? Albert Einstein, Richard Branson, Sir Winston Churchill, Toya Wilcox, Susan Hampshire, AA Gill, Anthea Turner and Tom Cruise to name but a few.

Chromagen™ lenses, originally designed to enhance colour definition for people with colour blindness, have proved to be very helpful in relieving the problems encountered by some people with dyslexia and other reading difficulties. They do not cure the condition, but they can help relieve some of the symptoms.

It is, however, necessary to correct all underlying visual defects, such as the need for spectacles, before trying Chromagen™ lenses. If you have not had an eye examination in the last twelve months you will need to have a full eye examination before your Chromagen™ trial can take place.

The lenses are available as either spectacles or contact lenses so are suitable for both children and adults with reading difficulties.

For more information on Chromagen™ please contact the practice on 01963 34333 or and we will be happy to send you full details.

Chromagen™ assessments and lenses are not available under the NHS.

Chromagen™ is a Cantor & Nissel product. Click here to learn more about the Chromagen™ system

Coloured Overlays for Reading Difficulties

If your reading difficulties are characterised by words that move on the page or patterns or glare on looking at white pages  you may benefit from coloured overlays.

Coloured overlays are sheets of coloured acetate that are placed over text when reading. In most cases only one colour is needed, although occasionally a combination of two or more colours gives a better result.

It is important that you have had a thorough eye examination before booking an overlay assessment, as all underlying defects must be corrected prior to trying the overlays.

If you have not had an eye examination in the last twelve months we would be happy to book you in, or you can attend your usual Optometrist and bring the prescription and / or spectacles with you. All children under 16years of age, and students under 19 years that are in full time education, are entitled to a basic NHS sight test free of charge.

For more information, or to book you or your child an assessment to see if coloured overlays would help reduce your reading difficulties, please contact us on 01963 34333 or email

When phoning to book an appointment please specify that it is for a Coloured Overlay assessment, as you will require a special appointment.

The assessment and overlays are not available under the NHS.
