The coloured lenses do help a minority of dyslexics. I am sure that the exercises will help some of those who are able to afford them, especially younger people. There is no magic cure for dyslexia their brains are wired up differently to the average brain.

On the plus side there is generally an increased ability to see the whole picture three dimensionally. This is why one American architect won't employ an architect unless s/he is dyslexic. He reckons that they don't forget something vital like how to get waste out of a building. He employs a clerical team to check spellings and maths.

Some of the wealthiest and most creative people in the world are dyslexic. They are the ones who make the most of the bonuses of the condition.

No I'm not dyslexic but I've taught them for the last decade or so.
