About Visual Stress When Reading

Some people find that text bends or blurs when they read; they may get headaches, this can be known as ‘visual stress’

Putting coloured plastic (an overlay) on the text can help some people to read faster and understand more. It may reduce eye-strain and they may need fewer breaks.

Changing the background and text colour on this website may also help.

A test (the Wilkins Overlays Test) may show that you will benefit from a coloured overlay.

If you have found a coloured overlay, or the colour change function on this website helpful you must see an optometrist to find out why.
See an optometrist who knows about reading through colour. They may say you need glasses or eye exercises.
