I offer coloured lenses to patients suffering from significant pattern glare and visual stress (ViS) – not just to those with dyslexia. I explain that in relation to dyslexia there is much controversy, and that the research tends to use outcome measures of increased rate of reading.

I feel that improved concentration, visual comfort, reduced symptoms, better comprehension and ability to read for longer are just as important as speed.

I use the most recent Delphi study protocols (Evans et al, 2017) for diagnosis of ViS and trial overlays before providing tinted lenses to avoid inappropriate prescribing.
