Product Information

Dyslexia assessor Georgina Smith says that coloured overlays can help people with visual stress as well as dyslexia. When Smith assessed some students, who were experimenting with coloured overlay rulers, the students said that they wanted to try their favourite colours at first. Smith thought that it was best for the student to try every coloured overlay ruler available to them for 10 – 15 minutes before deciding which colour worked best for them. Our top 3 dyslexia glasses & coloured overlays recommendations Likewise we found that in these dyslexics, who often complain of migraine type headaches, the blue filters often improved their headaches. Migraine was previously thought to be due to swelling of the arteries in the membranes surrounding the brain, the meninges. But we now believe that the hypothalamus and specifically the SCN is responsible. Blue coloured filters, worn as spectacles, have been found to be highly effective in reducing the frequency of migraine symptoms. So our blue filters are also often efficacious in reducing migraine. Essilor: Essilor is a well-known eyewear company that offers a range of lenses, including those designed for dyslexia. They have developed specific lens technologies, such as Eyezen lenses, which are designed to reduce visual fatigue and improve comfort during prolonged reading or computer use.

Proponents of this theory say that prescribed coloured eyeglasses or plastic overlays could alleviate perceived visual distortions. It is believed that the removal of this visual stress would improve reading and facilitate the development of reading skills in the longer term and help people with dyslexia. The simplicity of the intervention has helped it to become embedded into the practice of teachers, educational psychologists, optometrists and NHS orthoptic departments across the UK.

Myth versus evidence

The vision screening that most children undergo at school entry (age 4 to 5) is only a test of whether a child can see clearly in the distance. It is not a comprehensive assessment of eyes or vision and does not test any of the functions required for clear and comfortable vision when reading. For this reason, every child should have a full sight test when they start school, and as frequently as recommended by their optometrist after that. Our 10 scientifically selected colours; can be combined to make 30 tints equally around the colour spectrum Symptoms such as these have a variety of different causes, some of which may be due to disease or abnormality, so they must be investigated by a professional who is qualified to diagnose them correctly and give appropriate treatment. Anyone who experiences such difficulties associated with reading should consult a registered optometrist for a full assessment of eye health and visual function.

There are different types of colour filters that can aid reading for people with dyslexia. Find out all about dyslexic glasses and overlays here. How do Tinted Glasses and Lenses Work? 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. Contrary to the coloured lenses research that was conducted in 1999, coloured overlays can be looked upon as controversial. This is because, in an experiment conducted where some participants were asked to read text without an overlay and then with an overlay, there was no significant difference between the reading speeds for either method. For example, Emily, aged 7 when the experiment took place, had a reading speed of 49 correct words per minute (CWPM) without an overlay and 48 CWPM with the overlay. The overlays being referred to as dyslexia overlays can also be considered controversial because they do not only help people with dyslexia, but they can also be beneficial for people with dyspraxia and AD(H)D. What Colour Overlay is Best for Dyslexia? Research has demonstrated that people with dyslexia often have difficulty processing and representing the specific sounds of language. As a result, someone with dyslexia will experience difficulties in associating printed letters with relevant speech sounds, thus causing reading difficulties. Blue light therapy has also been shown to help people with sleeping problems, to improve alertness during night shift work and to help overcome jet lag. This probably also works on the suprachiasmatic nucleus to alter the timing of diurnal rhythms. We found that children whose reading benefitted from wearing blue filters during the day also often reported that their sleeping patterns had improved, and we showed that this was probably due to an effect on the SCN; at night secretion of the sleep hormone, melatonin, which is also under the control of the SCN, can be inhibited by just 15 minutes of blue light ie blue light can reset the SCN rhythms to improve sleeping.Overlays are similar to the aforementioned tinted glasses. They come in a variety of colours to suit the personal preferences of each individual.

One side of the overlay has a matt coating. Some matt coatings can reduce transparency, but coloured overlays from Crossbow Education have been subjected to stringent testing to ensure that maximum print clarity is retained while reflected light from the overlay surface has been significantly reduced. Nevertheless, some people prefer using the gloss side of the overlay. To make matters worse English is littered with exceptions to the letter-sound rules. Compare bough, dough, lough, cough, enough! After all that effort on reading each word, many children can't remember the words they read at the beginning of a sentence to understand the whole thing. The majority of research on this topic has found little evidence of measurable effects on reading accuracy or comprehension. For example, the American Academy of Paediatrics found little to no evidence supporting the link to visual stress in explaining the reading difficulties of people with dyslexia. ChromaGen: ChromaGen lenses are designed to help with visual processing issues related to dyslexia. They use coloured filters to modify the wavelength of light entering the eye, which may help improve reading ability for some individuals.

So why the visual distortions?

While the use of this unsupported intervention may not pose an imminent harm, use of coloured lenses and filters might deprive people affected by dyslexia of effective interventions such as targeted phonics instruction, as well as waste valuable time and resources associated with gaining a prescription for coloured lens or sheets.
