Intuitive Colorimeter®

The Intuitive Colorimeter® is an instrument designed to identify the optimum coloured lenses required by some individuals who suffer from photosensitive problems.

This condition is the cause of some cases of migraine and is very often the underlying reason why some individuals struggle to read. Such problems are often wrongly labeled as ‘dyslexic’. Dyslexia is an umbrella term for many sensory problems which affect learning.

Coloured overlays are widely used by teachers in schools throughout the UK. If an overlay proves useful it is likely that precision tinted lenses will also be beneficial. Lenses can be used for writing as well as reading. They can also be worn to reduce glare. It is important to note that the most effective coloured overlay is unlikely to have the same colour as the optimal precision lenses.

The first step is to carry out a full visual check on any individual who suffers headaches or difficulties with reading. If it is felt appropriate to check for Visual Stress then the first part of the assessment will take approximately 30 minutes and in part consists of testing with optimum coloured overlays which, when placed over a page of text, can often lead to improved reading rate and accuracy.

Following the application of an overlay the individual is urged to use it both in the classroom or workplace and at home during the ensuing weeks. If improvements are noted and sustained then a further test using the Intuitive Colorimeter® will be carried out, when the optimal colour may be identified.

The extent of the problem varies in each individual and whilst some may show vast improvements (sometimes as much as 12 to 80 words per minute) others may merely find reading more comfortable when using the appropriate overlay but this, in itself, may lead to more interest in reading.

Thousands of children each year are helped to improve reading using overlays and/or coloured lenses. It is our wish to help as many children as possible locally to overcome their reading difficulties and to move on educationally.
