Hi All I have recently bought and purchased my Irlen/Tinted lenses, this is a short video, but the lenses have such a profound affect on my visual perception issues and learning difficulties. Background I was diagnosed with Scotopic Sensitivity Syndrome in 2012 by James Billett an Consultant and Irlen Specialist who has been the field of special needs for over 20 Years (including Autism, Asperger's Syndrome, Dyspraxia, Dyslexia, Dyscalculia, ADD,ADHD & Learning Disabilities). Through this primary diagnosis many perceptual agnosias and learning difficulties were also recognised. I hope this helps other people on the spectrum with visual sensory issues.
