But in July 2009, an issue of the journal Pediatrics contained a joint statement on learning disabilities, dyslexia, and vision. It was issued by the American Academy of Pediatrics, the American Academy of Ophthalmology, and the American Association for Pediatric Ophthalmology, among others, questioning the validity of this form of treatment. Do colored overlays help with dyslexia? An optometrist (previously known as an ophthalmic optician) will report 'perfect eye sight' when someone can see a letter chart without needing refractive correction (glasses), and when there are no (orthoptic) problems of co-ordination between the eyes. The perceptual distortions may occur quite independently of any refractive error, although they are often, but not always, associated with a mild binocular vision difficulty (i.e. a difficulty in moving the eyes together, keeping the direction of gaze appropriately co-ordinated). In most cases the binocular difficulties do not appear to be the basis for the distortions.

Optometrists have found that Irlen lenses or Irlen colored overlays on text may alleviate visual stress symptoms. When the problematic wavelength is filtered out, the text is clearer, and eye strain and headaches are reduced. But disagreement among researchers still exists over the mechanisms and theory behind the filters’ effects. And debate still rages surrounding the fundamental issue of which colour is needed to achieve optimal results. Myth versus evidence

It is often the case that one person will benefit from overlays of one colour, and lenses of another colour. If lenses are to be worn, it is important that a separate professional assessment is carried out. There are two widespread approaches to testing for coloured lenses. One is carried out by a specialist optometrist using the "Intuitive colorimeter", a piece of equipment designed by Professor Arnold Wilkins in conjunction with the Medical Research Council and marketed by Cerium Visual Technologies, which will identify precisely the chromaticity of the illumination of a piece of text most effective in increasing reading speed, giving a measurement that is then used in prescribing tinted lenses. A list of recommended optometrists who test for coloured lenses with the Intuitive Colorimeter can be found here The theory of colored overlays being a treatment for dyslexia derives from cases of dyslexia being attributed to Scotopic Sensitivity Syndrome (SSS), also known as Irlen Syndrome or Meares-Irlen Syndrome.

The precise routine will vary from one optometrist to another but the basic eye test includes refraction (tests of lens focus), acuity (ability to see small objects), tests of the health of the eyes, and basic tests of ocular motor function (how well the eye muscles work together). There are other tests that are not always included in the examination but are generally thought to be particularly important for children with reading difficulties. You can ask an optometrist whether they would do these tests before you book an appointment:Bright blue light can also improve auditory attention, suggesting that the effects of light on alertness and attention are automatic and not mediated by conscious visual perception. Rather they are mediated by this retino-hypothalamic synchronising system.

There is no evidence to suggest that eye exercises, behavioural vision therapy, or special tinted filters or lenses improve the long-term educational performance of people affected by dyslexia or other learning disabilities. Children who persist in using their overlay usually find coloured glasses more convenient to use. Classes can help with writing, whereas overlays cannot. The degree of precision in the choice of colour is critical for obtaining the best results, and the precision available with lenses is far greater than with overlays. Perhaps for this reason glasses often give better results 4. But how effective are colored overlays in helping people with dyslexia? This article discusses colored overlay effectiveness and how Speechify helps with reading performance and fluency. What are colored overlays?Speechify AI Avatars & Video Create polished videos without any actors or equipment. Turn any text into high-quality videos with AI avatars and voiceovers – in minutes. Sheryl M.Handler and Walter M.Fierson – Reading difficulties and the pediatric ophthalmologist (December 2017). That being said, here are a few popular brands and technologies that are commonly associated with dyslexia glasses and lenses: The main aim of DRT research into visual and auditory weaknesses in poor readers is to develop treatments that will help them, and to prove by properly controlled trials that they work. We have shown that simple treatments such as viewing text through blue or yellow coloured filters, musical training or eating oily fish, really can help children to learn to read. No evidence was found for any immediate benefit of Irlen colored overlays as measured by the reading-rate test or the global reading measure. The data suggests that Irlen colored overlays do not have any demonstrable immediate effect on reading in children with reading difficulties.
