Irlen screening

Irlen Syndrome is a visual perception problem corrected by use of color tinted lenses or color overlays for reading. Certified Irlen screeners are educators who are trained to identify Irlen Syndrome and determine which colored plastic overlay will most improve reading capabilities.

The symptoms often associated with Irlen Syndrome include:

  • light sensitivity
  • problems with high gloss white materials
  • poor reading abilities
  • attention deficit
  • strain or fatigue
  • poor depth perception
  • headaches
