Although Lexilens® eyewear looks like a standard spectacles, its effect on dyslexia does not come from correcting the sight. It rather alters the way the image is processed by the brain (image acquired through the eyes) by using stroboscopic means. These are pulses too fast to be seen by a human being and backed by numerous scientific papers around the world.

For those requiring sight correction also, it can be added to the Lexilens® via a provided clip-on (lenses not provided). Please refer to your local optometrist to install prescription lenses to the provided clip-on.

Lexilens® declutters the image generated by the brain. As a result, the immediate effect is an easier reading. The second effect is that the information processed by the brain is cleaner and can be stored & retrieved more effectively. The impact on memorization requires a regular use and shows improvement after a few weeks, this delay vayring from one person to the other.

Dyslexia is a learning disability with many faces. Reasearch is still ongoing and we can’t provide a definitive answer at this stage. Yet many users with different forms of dyslexia confirm the positive impact of Lexilens® on their lives.

A recent survey in France showed a 90% satisfaction of Lexilens® users.

In some specific cases, the results are less spectacular. That’s why we continue research every day to help those affected by a less common form of dyslexia.

We do NOT recommend using Lexilens® if you are subject to epilepsy seizures. Lexilens® relies on stroboscopic effect to ease the reading and, although the stroboscopic frequency used is out the epilepsy range (around 40Hz), we do NOT recommend using Lexilens® in this case.

You need to adjust the speed parameter.

Lexilens® making your reading more difficult is a good news because  it means two things:

  1. Lexilens® is effective on you.
  2. You need to adjust settings on the app.


Lexilens® is compatible with most digital media sources.
To use Lexilens® with a screen, set the screen brightness to the maximum.

WARNING : Most screens have a 45° polarization angle while Lexilens® has a vertical polarization angle, which means you’ll be able to read the screen with Lexilens®. Only some very rare screen models display a horizontal polarization angle, which is non compatible with Lexilens®.


It is possible to add corrective lenses inside Lexilens® frames by adding the provided clip-on. This is a very common system in the optical world, used in particular to display sports glasses. Please refer to your local optometrist to add prescription lenses to your clip-on.

Flickering is caused by some surrounding light types (stroboscopic lights such as neons or some LEDs) interfering with Lexilens stroboscopic effect.
Optimal reading experience requires you avoid such flickering by turning away from this stroboscopic light.

Prefer to use Lexilens® under LED-type lighting rather than neon-type lighting.
