Treating reading difficulties with colour: Authors’ reply to Evans and Allen

Abstract

We thank Professors Evans and Allen for their interest in our article.1 2

The charity websites we reviewed refer to colour as though it offers a scientific, evidence based treatment; none referred to feedback from the membership. For example, one charity website makes the claim that “Research in the UK and in Australia shows that people who need coloured filters, who are said to have visual stress, need to have exactly the right colour.” This is incorrect. The research overwhelmingly shows little advantage, or at best conflicting results.3 4 5
