“Irlen® Overlays are the original coloured overlay technology. They are used by hundreds of thousands of students and over one-million people worldwide.
Irlen® Overlays are the only coloured overlays available backed by more than a decade of scientific research and used by more than 4,000 school districts worldwide.
Coloured overlays are most effective for individuals whose difficulties are isolated to reading. If you experience challenges with writing, math, depth perception, night driving, or the environment, coloured filters (worn as glasses) will be your best treatment option.
However, coloured overlays are an important first step in determining whether the Irlen® Method can work for you.

“The use of Irlen® Coloured Overlays and filters may provide the fighting chance many at-risk readers deserve.”
— The Reading Teacher. William Henk, Ed.D, Associate Professor of Education and Reading Pennsylvania State University.
“After 3 months of using Irlen® Coloured Overlays, students demonstrated significant improvement in reading achievement with gains between 1 year 8 months to 2 years 8 months.”
— Australian Journal of Learning Disabilities
“Our research has shown an immediate and significant increase in reading speed using coloured overlays.”
— Applied Psychology Unit, Cambridge University
“…significant improvement in reading comprehension and rate for those using Irlen® Spectral Filters.”
— Dr. Greg Robinson, University of Newcastle
“After one week, those that received the correct Irlen® Coloured transparencies gained 6.6 months in reading accuracy and 19.35 months in reading comprehension.”
— Journal of Reading Disabilities

Please consult an Irlen® Specialist to determine the best colour correction for you.

NOTE: Coloured lenses provided by optometrists and vision specialists to treat reading problems are NOT the same as the Irlen® Method. These professionals do not have the right colours, or diagnostic process for colour selection. Inaccurate colour selection can result in headaches, eye strain, and fragmented brain processing resulting in more distortions and reading problems.”
