Mears-Irlen Syndrome is also known as Scotopic Sensitivity Syndrome, Visual Stress & Pattern Glare. It is a visual processing disorder, in which people experience a number of different symptoms including:
- skipping words &/or lines when reading
- photosensitivity (sensitivity to light)
- blinking or squinting when reading
- poor concentration
- difficulty with depth perception
- tiring quickly when reading
- difficulty writing on a line
- being easily distracted when reading
- difficulty remembering what has just been read
- Visual disturbances
Mears-Irlen Syndrome is a visual perception problem where the nervous system has difficulty coding & decoding visual information. People with this condition see differently to others but are unlikely to realise this until diagnosis. You can view how text on a page, text under different lighting conditions & general vision looks to someone with Mears-Irlen Syndrome here. There is also a very informative YouTube video that shows the ways in which people with Mears-Irlen Syndrome see text.
Individuals affected by Mears-Irlen Syndrome can be helped with the use of coloured overlays to put over text or precision tinted lenses, the colour of which is determined by a test using an Intuitive Colorimeter, invented by Prof. Arnold Wilkins of the University of Essex.
