Studies Have Revealed No Link Between Eyesight And Dyslexia

Having conducted tests on over 5,800 children, research teams from Bristol and Newcastle Universities have concluded that there is no link between eyesight and dyslexia.

Co-author of the report Alexandra Creavin has stated that eye and vision problems are “very unlikely” to be the cause of dyslexia, which has in turn raised doubts as to whether coloured overlays or lenses are actually helping dyslexic children to read.

Over 14,000 children studied

Creavin and her team’s research draws from a lengthy tracking study conducted in the Bristol area, they have been following the development and health of over 14,000 children since the 1990s. Around 3% of these children have severe dyslexia. Researchers used a sample size of 5,822 children from this large study and conducted extremely detailed eye exams out on the dyslexic and non-dyslexic participants. The results show that dyslexic children where no more likely or unlikely to suffer from eye or sight related problems than the other children. In fact, the study found that many of the dyslexic candidates had “perfect vision.”

Most Dyslexic children have normal vision

Studies Have Revealed No Link Between Eyesight And DyslexiaCathy Williams, lead author and a pediatric ophthalmologist said: “some practitioners feel that vision impairments may be associated with dyslexia and should be treated. However, our study results show that the majority of dyslexic children have entirely normal vision on the tests we used.”

Following this study, there are bound to be discussion as to whether assistance such as coloured filters and tinted lenses actually help dyslexic children to read. Dr Creavin has stated that the research proves there needs to be cleared, fact-based guidance given to parents about how to help their children.

Coloured filters may benefit some

Kate Saunders, chief executive of the British Dyslexia Association, added, “some children and adults report benefits” from using lenses and filters whilst reading. She also stated that reading tests showed that these tools can help people with dyslexia.

Director of education and policy at Dyslexia Action, John Rack, says the charity supports the Williams’ and Creavin’s research fully. “However,” he continued, “not everyone has followed us in following the evidence, and the view that dyslexia is rooted in some problems in vision or visual processing is still widespread.

“The confusion comes in part from the fact that a minority of people who are dyslexic do find that text is significantly clearer when viewed through a coloured filter or lens. And some who are not dyslexic experience the same kind of benefit.”
