Where is Irlen supported?

Female Irlen Lenses2 There are presently over 7,000 educators trained as Irlen screeners. Over 100,000 adults and children wear Irlen Filters and millions of individuals are using Irlen Coloured Overlays. Massachusetts, USA and Alberta, Canada have bills pending to require screening for Irlen Syndrome in all schools in these states. Alabama has recognized Irlen Syndrome/Scotopic Sensitivity as a learning disability and all recommendations including the use of Irlen Spectral Filters must be allowed.

The Medical Research Council at Cambridge University, the Visual Perception Unit of Essex University in England, the University Laboratory of Physiology at Oxford University and the Newcastle University in Australia have extensively researched and published studies on Irlen coloured overlays and Irlen Spectral Filters.
