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.
Coloured Overlays
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.
Colorimetry
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.
It is not an eye examination & anyone over the age of 7 is suitable.

I’m a qualified Optometrist since 1990, registered with CORU. I’ve practiced in private practice, in large multiples & I’ve taught Optometry students in TUD for over 12 years.
I know firsthand that routine eye examinations do not cater for the symptoms experienced by the dyslexic learner when reading.
I’ve a special interest in Visual Stress experienced by dyslexic learners & I’m passionate about the benefits of coloured overlays.
