What is Irlen Screening?
Irlen Syndrome, or Scotopic Sensitivity Syndrome, was first identified by Educational Psychologist Helen Irlen while she was working with adult learners in the early 1980’s. Until described in her book, Reading by the Colors (Avery Press, 1991), there was no explanation or treatment for this perceptual disorder, and many people with this disorder would be misdiagnosed as dyslexic or slow learners. In 1991, Dr. Margaret S. Livingstone of Harvard Medical School published research which offered a medical explanation for this disorder.
