Irlen Syndrome, also known as, Scotopic Sensitivity Syndrome (SSS) is a type of visual perceptual problem. It is not an optical problem. It is a problem with how the nervous system encodes and decodes visual information. Academic and work performance, behavior, attention, ability to sit still and concentration can all be affected. Individuals with this problem see the printed page differently, although they may not realize that they do. Having Irlen Syndrome keeps many people from reading effectively, efficiently, or even at all. Until now, it has baffled educators and medical scientists because it is undetected by standard visual, educational and medical tests. Irlen has a patented treatment-method which uses specially formulated, coloured overlays or coloured lenses worn as glasses or contact lenses to reduce or eliminate perception difficulties.
