    About the Irlen Method

    Irlen Syndrome or Scotopic Sensitivity Syndrome was first identified in the early 1980’s by Educational Psychologist Helen Irlen. Helen Irlen at that time, was Director of the Learning Disability program at California State University in Long Beach, California. Before the syndrome was described in her book, Reading by the Colors, perceptual reading difficulties was yet unknown and there was no treatment available for it.

    Although the symptoms are similar to dyslexia, the Irlen Syndrome differs in that the symptoms are caused by light sensitivity issues of an individual. Many people were, and still are, misdiagnosed as dyslexic, slow learners or being identified as ADHD.

    The Irlen Method is a revolutionary and non-invasive technology using coloured overlays and spectrally modified filters (lenses) worn as glasses which allows the brain to properly process visual information accurately. The Irlen overlays and filters on the lenses reduce light sensitivity and can greatly improve reading fluency, comprehension, concentration and attention.

    Facts About Irlen Syndrome

    The Irlen Syndrome occurs on a continuum from mild to extremely severe.

    Mild Profile
    normal or high achieving person who reads slowly or must reread more than usual for comprehension

    Moderate Profile

    Other Irlen Syndrome Facts

    • 45 – 50% (some say 65%) of dyslexic population has Irlen Syndrome (Whiting 1985)
    • 50% of ADD, ADHD population have Irlen Syndrome (Irlen, 1993; Jordan, 1996; Payne, 1994)
    • 45 – 50% of population with just a reading disability has Irlen Syndrome as the main cause

    Three-Dimensional Brain Scans

    These three-dimensional brain scans using SPECTtechnology show the portions of the brain that are in heavy use, or 'hot'. Both scans are of the same brain without, and then with, Irlen Filters.
