Purpose
There are many anecdotal claims and research reports that coloured lenses and overlays improve reading performance. Here we present the results of a systematic review of this literature and examine the quality of the evidence.
Methods
We systematically reviewed the literature concerning the effect of coloured lenses or overlays on reading performance by searching the PsychInfo, Medline and Embase databases. This revealed 51 published items (containing 54 data sets). Given that different systems are in use for issuing coloured overlays or lenses, we reviewed the evidence under four separate system headings (Intuitive, Irlen, Harris/Chromagen and Other), classifying each published item using the Cochrane Risk of Bias tool.
Results
Although the different colour systems have been subjected to different amounts of scientific scrutiny, the results do not differ according to the system type, or whether the sample under investigation was classified as having visual stress (or a similarly defined condition), reading difficulty, or both. The majority of studies are subject to ‘high’ or ‘uncertain’ risk of bias in one or more key aspects of study design or outcome, with studies at lower risk from bias providing less support for the benefit of coloured lenses/overlays on reading ability. While many studies report improvements with coloured lenses, the effect size is generally small and/or similar to the improvement found with a placebo condition. We discuss the strengths and shortcomings of the published literature and, whilst acknowledging the difficulties associated with conducting trials of this type, offer some suggestions about how future trials might be conducted.
Conclusions
Consistent with previous reviews and advice from several professional bodies, we conclude that the use of coloured lenses or overlays to ameliorate reading difficulties cannot be endorsed and that any benefits reported by individuals in clinical settings are likely to be the result of placebo, practice or Hawthorne effects.

Wednesday, September 21, 2016
A children’s hospital in Queensland has indicated it will not refer its patients to behavioural optometrists for collaborative care.
Do read the full piece.The spokesperson cited a joint statement released in 2009 by the American Academy of Pediatrics, American Academy of Ophthalmology, American Association of Pediatric Ophthalmology and Strabismus, and the American Academy of Certified Orthoptists, which stated:
“...vision problems are not the cause of primary dyslexia or learning disabilities. Scientific evidence does not support the efficacy of eye exercises, behavioural vision therapy, or special tinted filters or lenses for improving the long-term educational performance in these complex paediatric neurocognitive conditions.
“Diagnostic and treatment approaches that lack scientific evidence of efficacy, including eye exercises, behavioural vision therapy, or special tinted filters or lenses, are not endorsed and should not be recommended.”
The spokesperson added, “Further, in 2015, the American Academy of Pediatrics suggested that there is no indication to routinely refer children diagnosed with specific reading impairment to an ophthalmologist or optometrist, and that these children should have non-vision based support.
“The LCCH ophthalmology department has taken the position not to align with optometrists who practise behavioural optometry. However, we welcome optometrists who wish to join us in practising evidence-based care.”
