Research-based visual stress support products since 2004: coloured page overlays, reading rulers, visual stress software, tinted magnetic marker boards, tinted exercise books and reference books on visual stress.

Unmatched clarity and quality: our coloured overlays and reading rulers are made of virgin PET manufactured specially for Crossbow, and they have a special scratch-resistant coating.

"BDA Assured"
 BDA Assured was a programme run by the BDA from 2019-2021 which gave the “BDA Assured” badge to resources that were recognised by the BDA as being helpful to people with dyslexia.  During that time, Crossbow reading rulers and coloured overlays were part of the scheme, and some of our products are still in circulation with the BDA Assured badge.  This programme has now been discontinued by the BDA.
