Salient facts about Irlen Syndrome and Irlen Spectral Filters
Many clients with Irlen Syndrome will manifest distractibility, poor attention, and sometimes they may even show signs of impulsivity and difficult behaviours. Psychotropic medication may improve the situation somewhat, but some issues will usually remain. The use of Irlen Precision Spectral Filters will resolve the issue without the need for medication intake. Irlen syndrome is a neurological dysfunction where the bundles of neurons involved in the processing of visual information cause the hyperactivation in the visual cortex. Irlen syndrome is often confused with ADD/ADHD (30%) and dyslexia (46%). Ironically 30% of all psychotropic medications prescribed do not seem to be effective. In the case of Visual Migraines, Irlen Spectral Filters have been proven to reduce significantly the occurrence of the episodes and also reduce or eliminate the symptoms.
Positive clinical explorations are ongoing with American Soldiers returning from the theatre with concussions and other brain injuries. Irlen Spectral Filters are found to reduce symptoms associated with such traumas. More and more, professional athletes having suffered concussions are fitted with contact lenses fitted with individually adjusted Irlen filters.
So what about Irlen Syndrome?
Irlen syndrome is not a problem of the eye, but of the brain. Optometric interventions will not resolve Irlen Syndrome-related complaints, just as an intervention aimed at Irlen syndrome will not have any effect on optometric issues. Consequently, Irlen practitioners require that a client pay a visit to an optometrist or ophthalmologist, ideally no more than six months prior to an Irlen assessment.
There is a substantial body of research that has been accumulating since the 1980s. The efficacy of Irlen Spectral Filters is supported by more than 100 studies led by independent researchers who published their results in peer-reviewed, respected professional journals in the fields of education, medicine, and psychology. Among those, we can find the Journal of Learning Disabilities, Australian Journal of Special Education, Perceptual and Motor Skills, Australian Journal of Learning Disabilities, Journal of Clinical & Experimental Neuropsychology, Journal of Research in Reading, Behavioral Optometry, and Opthalmological and Behavioral Optics. A recent review established that of 62 selected studies, 56 had given positive results, 45 noted significant improvement in the case of specific reading skills, 11 gave positive results for optical accommodation, improved eye movements and reduced headaches and migraines. Studies are ongoing in Australia, Italy, Brazil, England, Switzerland, and New Zealand.
Key studies presented below are worth mentioning and should elicit professional interest:
