Visual Perception Testing Ann Bonvallet, Irlen Syndrome Diagnostician Ann Arbor, MI 48103 Phone: 734-663-5590
While teaching learning disabled students in Ann Arbor Ann saw CBS’s report on Irlen tinted filters and their benefit for LD readers. This innovative treatment, which corrects visual distortions, was developed in 1983 by Helen Irlen, an educational psychologist in Long Beach, California. Irlen Syndrome is an abnormal response to certain wavelenghts of light causing visual distortions of print that can make perception a difficult part of reading.
Jonathan, originally a fourth grader diagnosed as dyslexic, reported to Ann that with Irlen filter overlays the print was no longer faded, blurry, squashed together or moving. Later he said “With my Irlen filter lenses I read well, don’t write backwards, and I spell fine. The white flashing is gone. I can be under fluorescent lights or look out the window and I don’t get headaches.” With the Irlen filter tint Jonathan no longer needed special education services and has graduated from Purdue University with honors in engineering.
