Reducing visual stress for the dyslexic learner with coloured overlays
The problem for dyslexic readers
Visual stress & discomfort experienced by dyslexic readers varies but can include:
These symptoms fall into visual stress, visual dyslexia or scotopic sensitivity syndrome.
How coloured overlays can help dyslexic readers
In many cases the symptoms experience by dyslexic readers may be remedied by reading through coloured overlays that filter out certain wavelengths of light.
This is done by placing coloured plastic overlayed on the print.
Not everyone is comfortable with black & white text.
If you filter out the light wavelength that dyslexic readers are sensitive to, the visual stress is reduced & the rate of reading improves.
For each individual, there is a specific hue (colour) & saturation (strength) that will work best.
Colorimetry will strive to identify the precise colour that is most effective in reducing the visual stress & increase the reading speed & comfort.
Coloured Overlay Assessment
A Coloured Overlay assessment takes up to 1 hour.
