Two Breton researchers, Albert le Floch and Guy Ropars, received the Academy of Medicine prize in December for a discovery that could improve the lives of people suffering from dyslexia. They are not doctors but physicists. They found a way to make reading easier for people with dyslexia.

After years of studying light, they became interested in the eyes and in particular a microscopic area of ​​the retina, Maxwell’s spots. People with dyslexia are a little different.

In dyslexics, no ocular dominance

The hypothesis of these researchers would be that dyslexics do not have ocular dominance. Not everyone agrees, there is a lot of work on the mechanisms of dyslexia and ultimately not much is known in this area. According to them, the brain is constantly juggling between the images sent by the left eye and those sent by the right eye. The images are superimposed, are deformed, like optical illusions.

A tromboscopic lamp

Physicists have found a way to make these images more readable by tinkering with a strobe light. Guy Ropars explains how it works: “There is therefore a parasitic image that will have to be erased knowing that this parasitic image occurs a few milliseconds after the main image. So the idea is to use a pulsed system that will turn off for do not see this parasitic image. Up here, the lamp is on here it is off see it is on for a short time and off for quite a while “.

In 2017, an industrialist stumbled across their study a little by chance and decided to develop this discovery by creating glasses for people with dyslexia. It’s exactly the same system, but in miniature. The person who uses them just has to make a setting via an app to choose the frequency that corresponds to him.

Marie is dyslexic, she tested these glasses, this is what she thinks: “Before, without the glasses, I got tired a lot faster, I stopped because I thought I was never going to get there, that it was over, that I was zero. But in the end, since there was these glasses helped me to tell myself that yes, I can read like everyone else. It’s a revolution. It helps a lot. It’s super useful! “In addition to this, you need to know more about it.

These glasses have been marketed as a child model for 3 months by a famous chain of opticians. But that’s a budget, because they cost 399 euros and it’s not a quick fix either. They do not work for all people with dyslexia.
