Dyspraxia, a co-ordination disorder also known as "Perceptuo-Motor Dysfunction", has been shown to co-exists with Visual Stress, Dyslexia and other neuro-perceptual difficulties. It is thought to affect up to 10% of the population and up to 2% severely. Statistically, it is likely that one child in every class of 30 children has dyspraxia. Precision colour filters have been shown to help many with dyspraxia overcome their depth perception difficulties.
Daisy Argyle had done a great job of creating these sample distortions. I can't imagine trying to read with the letters all double like this. It is images like this that make those of us who do not suffer from these distortions, more sympathetic to those that do suffer, and more driven to get the awareness and support up, and the solutions out where they can get into the hands of those who need them.
Once an overlay of the correct colour is applied to the reading material, there is, what I have heard referred to, a WOW moment, when the words stop moving, come together, or just calm. It is this moment, and all that follow, that we are trying to achieve with screening programs and the availability of overlays and related tools.
Simply overlaying a coloured acetate can help reduce the distortions of text experienced by individuals with Visual Stress. Although this is sometimes also referred to as Visual Dyslexia, Visual Stress is a separate condition. It does co-exist with Dyslexia and Dyspraxia and should be tested for if either of these conditions is suspected.
