"I have repeatedly seen dramatic, instantaneous response to using Irlen Filters and other transparent overlays; I am now convinced that Scotopic Sensitivity does exist and that it may be responsible for many of the so-called learning disabilities in our schools. I also believe that screening for Scotopic Sensitivity Syndrome should be a regular part of every school health program."

LouAnne Johnson, author of the best selling book The Queen of Education, Rules for Making Schools Work, which inspired the movie Dangerous Minds

"There is so much evidence that Irlen coloured filters can literally transform a child's outlook on life that it makes sense to offer Irlen overlays or glasses to every child who needs them."

Felicity Craig, author of Conquering Dyslexia 

 "Autistic individuals who have benefited from the Irlen Method report seeing better, feeling more relaxed, less sensitive to bright lights, having fewer perceptual distortions, and better fine and gross motor coordination."

Olga Bogdashina, author of Sensory Perceptual Issues in Autism and Asperger Syndrome

"During a 15-month period, I evaluated 460 patients, including both adults and children. Using questions that would uncover problems related to light sensitivity and reading difficulties, I found 122 patients. Many were treated with (Irlen) tinted lenses and were enthusiastic about their improvement. For these patients, Irlen Syndrome is an authentic diagnosis.

Robert Dobrin, M.D., F.A.A.P.

 "...our feeling as disinterested outsiders is that the technique developed by Helen Irlen addresses a severe, unmet need in the community, has promise, and has benefited many individuals but requires further validation. We look forward to seeing the results of further work in this fascinating area."

David M. Hailey & Anthony R. Lea, Health Technology Division, Australian Institute of Health

 "Should reading educators support an approach that works for some children without knowing why it does? At the risk of sounding scientifically premature, we think they should ... The use of (Irlen) colored overlays and filters may provide the fighting chance many at-risk readers deserve."

William Henk, EdD., Associate Professor of Education and Reading, Pennsylvania State University, Robert J Rickelman, Millersville University

"For the past 10 years my clinics have screened all our patients for Irlen Syndrome. When appropriate, we have made many referrals to Irlen Clinics and our patients have successfully used the Irlen Filters to alleviate many symptoms, including headaches, learning and reading problems, light sensitivity, and depth perception issues.

In performing before and after scans with the Irlen Filters as the only intervention we have seen the brain become significantly more balanced. I have often been amazed at the improvements our patients have expereinced. My sense is that the lenses help to filter out certain colors of the light spectrum that are irritating to brain circuits."
