Solid Ground Learning Notes - vol. 111
January 10, 2007
In my work as a Special Education teacher and Learning
Specialist, I have discovered that all children do not see
the printed page in the same way. Many children tell me
that they see double letters or letters that seem to fall
off the page.
Coloured Overlays Help Dyslexics
The result is that their comprehension suffers and they may
skip lines, change the order of the letters in the words,
or know a word on one page and not on another.
Eye specialists say that some children suffer from
"Perceptual Distortion" and placing colored overlays on top
of the printed page may help students see the page more
clearly.
Apparently, using colored overlays help eliminate light
wave-lengths before they reach the retina and the brain. As
a result, visual information may be more effectively
analyzed.
My understanding is that it is the contrast between the
letters and the page that causes the problem. I have had
children react as if the pages were too bright. The
overlays reduce the contrast and thereby, make the reading
process more comfortable.
It also appears that different colours work for different
people. The overlays come in red, yellow, 2 blues and
green. Experiment to find what works best for you.
