For parents, educators, and professionals, Irlen, a school psychologist, therapist, adult learning disability specialist, and specialist in perceptual processing disorders, describes the Irlen Method, which treats reading issues with the use of colored filters, and how it can be used to treat perceptual processing difficulties related to light sensitivity, headaches and migraines, attention deficit disorders, autism spectrum disorders, medical and visual conditions like fibromyalgia and macular degeneration, and head injuries and psychological problems. She details how she discovered the method through her work with struggling readers, the scotopic sensitivity syndrome now known as Irlen Syndrome, how to conduct a screening, home strategies, and how to use the method.
