I'd be interested to know if folks here with dyslexia agree with the sentiment that dyslexia affects their visual ingestion of words, and that visual aids (like the colored filters he discusses) can improve their reading ability.
I ask this because many dyslexia experts in the US (and some outside the US) insist that dyslexia is purely phonological, and therefore non-visual.
As someone who works in the field but does not have dyslexia, I have to reconcile these academic's edicts with the personal descriptions I hear from individuals with dyslexia, which clearly indicate that dyslexia can have visual causes and aids.
