Coloured lenses can help patients with dyslexia and similar difficulties with reading, such as Meares Irlen syndrome and pattern glare When prescribed correctly, coloured lenses can relieve the symptoms of perceptual distortion, eye strain and headaches in certain patients, and may significantly reduce the incidence e of migraine and photosensitive epilepsy.

We prescribe Precision Tinted Lenses incorporating individual optical prescriptions using our Intuitive Colorimeter. The instrument was developed by Professor Arnold Wilkins under the auspices of the Medical Research Council. More information about the research behind colorimetry can be found here.

Before prescribing precision-tined lenses it is common to use a special series of plastic overlays, to determine the effect of the colour on reading performance. This enables us to see if significant improvements in speed of reading can be made by the use of colour. The special testing using the Intuitive Colorimeter can be used where improvements are found. Thereby reducing costs of inappropriately using coloured lenses which are ineffective.

Dyslexia and Children

The children most likely to benefit from coloured lenses will often show the following symptoms.

  •   Headaches during or after reading

  •   Rubbing eyes

  •   Watering or red eyes

  •   A marked dislike of bright light (photophobia)

  •   A tendency to constantly shift or alter position of text whilst reading

  •   Complains of fatigue after a short period close work

  •   Complains of fatigue after short periods of close work (one or two pages)

  •   Print appears to be blurred, moving, flickering or fading.  Appearance of patterns in the print colours appearing around print      and doubling of letters or words 

Care needs to be taken in assessing these symptoms since many are associated with problems of focusing (accommodation) and with binocular vision or other vision perception problems. For this reason a full examination is recommended by an optometrist skilled both in binocular vision assessments and in dealing with children’s vision problems.

Dyslexia and Adults

Many adults suffer from exactly the same problems as children. Indeed children with unsolved problems become adults with a problem. Precision Tinted lenses and Vision Therapy are effective for both children and adults. Click here for more information on Vision Therapy.

Migraine and Photosensitive Epilepsy

There is increasing evidence that the use of precision tints for those with some types of migraine and photosensitive epilepsy can be of real help in reducing or alleviating their symptoms. We have helped many such people and are always happy to discuss the technique with sufferers.

Traumatic Brain Injury

Many patients have also found Precision Tinted Lenses of considerable benefit following accidents and strokes that leave them unable to concentrate on close work for long. It should be acknowledged that there are many complications in these cases and that this method is unlikely to help everyone. Nevertheless, we are happy to discuss details of individual difficulties and advise if this approach may be of help.
