COLORIMETRY

Do you find reading difficult or uncomfortable? Do you find words move on the page or run into each other? Do you suffer from sore, tired eyes and headaches after reading? If so, you may be suffering from Visual Stress or Meares-Irlen Syndrome and Colorimetry could help you.

Scientific research has shown that 'visual stress' can be reduced by colouring the page using spectral filters Allport Opticians can carry out special assessments to determine whether using coloured overlays when reading or wearing coloured glasses can relieve symptoms of visual stress.

Symptoms of Visual Stress

Movement of print
Blurring of print
Letters changing size or shape
Letters fading or becoming darker
Patterns appearing, sometimes described as 'worms' or 'rivers'
Illusions of colour-blobs of colour on the page surrounding letters or words
Rapid tiring
Headache or visual discomfort
Sore, red or watery eyes

Visual stress very often occurs in both dyslexic and non dyslexic individuals.

Our Colorimetry Service

Eye Examination

A full eye examination is important for everybody and in particular those suffering with reading difficulties. An eye examination can rule out many other problems with the eyes which may be causing or contributing towards any difficulty. Behavioural problems (with the eyes) in particular can contribute to reading difficulty. Checking for balanced binocular vision is particularly important.

Pattern Glare Test

A pattern glare test will be carried out for any individual with reading difficulty. This involves looking at a series of black and white patterns to see if visual distortion is present and to what degree.

Overlay Assessment

Depending on the age (and other factors) of the sufferer we may carry out an overlay assessment. We will usually do this if the patient is a child younger than ten years old. The overlay assessment will be carried out by one of our colour experts to determine specific symptoms of visual stress and the benefit colour is likely to offer the patient. This is an inexpensive way to see if colour will be helpful and is a much easier method of choosing for younger patients.

Colorimetry Assessment

Colorimetry is carried out for adults, older children and younger children with a sustained benefit from overlays. The Intuitive Colorimeter works by passing coloured gels in front of a light source and has over 100,000 different colour combinations to help relieve visual stress. The optimal colour is chosen by a process of elimination in which the colour, saturation and hue are independently adjusted for the patients comfort. The colour is then made into precision tinted lenses for the wearers comfort and convenience.
