I was diagosed with Irlen syndrome, had the glasses, lost the glasses, world caved in, now back to the way I was.
Personaly, its too much, the testing for a start, different filters paired up seemed never ending, a suitcase of different lenses, the tester got very frustrated/angry with me
it works for a lot of people, aparently, it didnt do anything for my bizzare behaviour, was it meant to?
Good luck mate, hope it works for you, I have loads if info on it, theres Irlen UK and Rainbow readers based in scotland, but as Helen Irlen was from Australia, and Meyers somebody was from somewhere else
