There are many research articles about the Irlen Filter Lenses and overcoming reading difficulties. Most of them show steady or dramatic gains in reading ages after the lenses were prescribed. Copies are available if required. A recent major breakthrough in research on dyslexia at Harvard University clearly links disorders in a person’s visual system as a major cause of dyslexia. A team of neuroscientists led by Dr Margaret Livingstone reported their research in the prestigious research journal Proceedings of the American Academy of Science. Their findings show that visual dyslexia is a result of the failure of the visual perception system’s neuro-circuits to keep proper timing, and that colour filters can correct this imbalance.

Even though there has been plenty of research to show that coloured lenses do make a difference, this has been the first major research to show why. Even more recently, Dr Jeff Lewine, neuroscientist and scientific director of the Center for Advanced Medical Technologies, of Utah University, using sophisticated instrumentation such as Magnetic Resonance Imaging and Magnetoencephalography has reinforced these findings. He says, “The data clearly demonstrated that most individuals diagnosed with SSS had a fundamentally abnormal pattern of information processing in which stationary stimuli caused abnormal activitation in brain regions involved in the processing of visual information. Even more intriguing was the observation that individually tailored coloured glasses suppressed the abnormal activity. The data also clearly indicate the ability of coloured glasses to remediate the relevant information processing handicap.” If you are interested in the research articles, please let me know.

Contrary to opinions often espoused, there is a lot of good scientific research into Irlen Syndrome, most of which is very positive. IT IS EVIDENCE BASED. Quite a few of the studies are double masked, randomised, placebo controlled and many are published in the peer reviewed (refereed) sections of reputable journals.
