Scotopic Sensitivity Syndrome / Irlen Syndrome: Use of Colored Filters and Lenses (student project)

[Dolphin]

Some people will probably have come across colored filters/lens - people in my family use them and I've heard them suggested for ME/CFS.

Anyway, here's a student project I happened to come across that looks like it reviews the literature.

Abstract

Scotopic Sensitivity Syndrome is a perceptual disorder that is suggested to underlie certain reading disabilities.

The use of tinted lenses worn or colored filter overlays used are claimed to improve reading performance and eliminate the problems associated with the syndrome.

The ten studies reviewed contained information about Scotopic Sensitivity Syndrome and how the colored filters or lenses effect reading.

When comparing reading rates, oral miscues, and comprehension levels with and without overlays or lenses, there is a fifty–fifty split in reading improvements.

The studies set no basic foundation for significant improvement documentation. In fact most studies have been found not to be valid.

Ta Dolphin. I tried looking in to the research around this stuff a while back, and wasn't sure what to make of it. Someone I know in the NHS had used it themselves, but was still unsure if it was quackery when I asked them about evidence for it's use. It always seemed a bit dodgy to me... but schools have been using it to 'help' kids with, and it seems to be in the 'mainstream'. I wonder how it ever came to be used.
