Colorimetry Information

Every child who displays problems with reading should be referred to an optometrist for a full eye examination. It is recommended that the chosen practice should also specialise in using the Intuitive Colorimeter.

As frustration and low self-esteem can occur in children who are underachieving due to visual stress, early diagnosis of the problem is essential. The longer it takes to identify and remedy visual stress, the greater the loss of confidence.



The Colorimetry assessment will take approximately one hour and is carried out by a fully qualified optician. Whilst sitting comfortably you will be asked to look into the Intuitive Colorimeter and shown different colour filters to determine which colour reduces disturbances in the text.

N.B. Young children may wish to bring a favourite book along with them.

On completion of the assessment the optician will interpret the results and spend time with you discussing the next course of action. If a precision tint is found to be beneficial, the optician will then advise you on the suitable frame selection to complement the coloured lenses and perform the necessary measurements for a pair of spectacles to be produced.

Precision tinted lenses have also been proven to assist with dyslexia: – a term used to refer to reading problems. Dyslexia is often associated with spelling difficulty.

Visual stress is NOT the same as dyslexia but is more common in those who are dyslexic. People who fail to read because of visual stress are frequently misdiagnosed as dyslexic. For this reason it is important that the existence of visual stress is identified at an early stage. Once visual stress has been alleviated, any remaining problems are easier to solve.
