All Products

All visual stress support products: coloured page overlays, reading rulers, visual stress software, tinted magnetic marker boards, tinted exercise books and reference books on visual stress.
A peer-reviewed study of Crossbow reading rulers and overlays can be found in the March 2019 edition of the journal "Vision Research."  For a summary of the article, click here.

Crossbow 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. Copycat reading rulers and overlays tend to be made of PVC.

PET is

  • Clearer
  • Smoother
  • Harder and less prone to scratching
  • Fully recyclable

PVC

  • Contains toxic chemicals
  • Has a slightly uneven surface, which affects the printing of the colours.
  • Is less clear and also softer and therefore prone to scratching.
  • Remains in the environment for millions of years.
