Irlen Syndrome or Scotopic Sensitivity System

  

 AT for Irlen Syndrome, also known as Scotopic Sensitivity Syndrome

Irlen Syndrome is a type of visual perceptual dysfunction. It is not an optical problem. It is a problem with how the nervous system encodes and decodes visual information. Academic and work performance, behaviour, attention, ability to sit still and concentration can all be affected.
Individuals with Irlen syndrome see the printed page differently. Irlen syndrome prevents many students from reading effectively and efficiently.
Until recently it has baffled educators and medical scientists because it has been undetected by standard visual and educational tests. Irlen has a patented treatment method using specially formulated colored overlays, or spectral filters worn as glasses or contact lenses, to reduce or eliminate perception difficulties.
