Coloured Overlays

Coloured overlays in a range of at least ten colours are a proven, research-based solution to the visual stress problems that often occur alongside dyslexia. Our coloured overlays are the only ones on the market manufactured in eco-friendly PET, and are of the highest quality and clarity. All crossbow overlays are measured throughout production for conformity to sample colours produced directly from the research findings of the dept of Visual Science at Essex University. There are inferior copies of our overlay range on the market, so look for the Crossbow brand for your guarantee of quality.

Peer-reviewed research on our coloured overlays and reading rulers  from a sample of 106 typical primary school children showed that "All but four children had reduced reading times with one of the reading aids and all but one reported their aid improved the perceived visual clarity of the text" (from the abstract: A comparison of the effects of the colour and size of coloured overlays on young children’s reading.
