Irlen Syndrome, also known as Scotopic Sensitivity is a perceptual problem that keeps many people from reading effectively, efficiently, or not at all. Until now, it has baffled educators and medical scientists because it is undetected by standard visual, educational and medical exams.

Individuals with Irlen Syndrome perceive the printed page differently and must constantly adapt to distortions from print or the background. They may suffer from slow or inefficient reading, poor comprehension, strain or fatigue. It can affect attention span, energy level, motivation, handwriting, and depth perception. Irlen Syndrome sufferers may be seen as underachievers with behaviour, attitude, or motivational problems. It is a complex and variable condition sometimes found to co-exist with learning disabilities.

In the United States and worldwide, there are many certified Irlen Screeners and Irlen Diagnosticians. These individuals are dedicated professionals – teachers and psychologists who share many years of experience in primary and secondary schools. Listed alongside are many of the symptoms associated with Irlen Syndrome. If you or someone you know suffers from any of these symptoms or has unexplained reading problems, you may want to want to contact an Irlen Screener or Diagnostician.
