  • Two physicists from Rennes will receive the National Academy of Medicine prize this Tuesday.

  • After fifteen years of research, they have succeeded in partially unraveling the mystery of dyslexia.

  • The cause of this reading disorder is believed to be hidden in tiny receptors in the eyes.

Their work published in October 2017 in the British journal

The Royal Society

has raised a lot of hope among the 700 million people with dyslexia around the world.

Rather wary at first, the medical world also hailed the research of Guy Ropars and Albert Le Floch.

Both physicists at Rennes 1 University, they will receive the prestigious prize from the National Academy of Medicine this Tuesday afternoon.

They are strong Albert Le Floch and Guy Ropars @ UnivRennes1!

They had already pierced the secret of the viking compass (# em6 n ° 721) they offer an incredible explanation of the origin of #dyslexia.

“It's always nice to see his work recognized after long years of research,” says Albert Le Floch, now retired.

It is all the more surprising that we are physicists and that we are rewarded by the Academy of Medicine ”.

Symmetrical eyes cause confusion in the brain

For fifteen years, the two researchers were interested in light in order to determine if it played a role in learning disabilities to read.

Their work led them to magnify tiny receptors in the eyes called Maxwell's spot centroids.

It is in this area of ​​the retina, the fovea, that they believe is one of the causes of dyslexia.

“In those who are not affected by this disorder, these light receptors are asymmetrical and do not have the same shape from one eye to the other, explains Guy Ropars.

Whereas in people with dyslexia, Maxwell's two tasks are identical ”.

The absence of a directing eye in these people would thus lead to confusion in the brain by creating "mirror images" between which it is unable to choose.

Lamps and glasses on the market

In an attempt to correct this anomaly of the eye, the two scientists have developed a lighting system that erases this “mirror image” which bothers people with dyslexia.

"We make sure to erase the table so as not to disturb the reading," says André Le Floch.

Since their discovery, nearly 200 families have come to test their "miracle lamp" in their laboratory at the university.

With almost 90% conclusive tests according to them.

"Children have managed to read a text for the first time without any problem," says André Le Floch.

In any case, the discovery of these two Breton scientists is of great interest to industrialists.

Inspired by their work, the start-up Lexilife presented at the beginning of the year at CES in Las Vegas a reading aid lamp for people with dyslexia.

The optician Atoll has also just launched glasses on the market to facilitate reading.

"We let them do their business," smiles André Le Floch.

We don't do this for money, but to improve science ”.
