In relation to design it's even simpler to realise the downfalls in what is actually a very affective method of helping dyslexics. Colourimetry is the use of coloured lenses or overlays in order to make reading easier. Think about it. How often do you look at a bright white page with black lettering and your head goes a little fuzzy? Or twinkly in my case. By using coloured overlays it helps to relax the eyes and aid reading - however it has aprox and 80% failure rate as children just don't use them.
A proved aid is being ignored because overlays are cumbersome and glasses hold a certain stigma - in particular at a young age - so is there an easier way?
Let's see over the year!
