Reading comfort, grounded in clinical research
The Science Behind Lili
What Lili Works On
Reading happens in two steps: the eye and brain first take in the visual shape of a word, then access its meaning. For many dyslexic readers, visual interference appears at the first step: letters seem to overlap, crowd or fade.
Lili's pulsed light works precisely on this visual step: it helps steady the letters so the word reaches the brain more clearly, and reading flows more easily. Drag the slider across the image to see the difference.

With Lili
From Discovery to Clinical Studies
2017
A Discovery in France
The original research into using pulsed light to support reading for people with dyslexia began in France.
2020
Institutional Recognition
The Académie Nationale de Médecine, founded in 1820, recognized the interest of this research.
2022
First solution on the market
Launch of the portable Lili reading lamp.
2026
Range extension and validation
Launch of the Lili Screen.
Completion of two independent clinical studies conducted with the CNRS and Robert-Debré University Hospital, led by Maria Pia Bucci.
A rigorous scientific protocol
2 complementary clinical studies
Conducted between 2025 and 2026, these two randomised, double-blind clinical studies scientifically measured:
- The effects of the Lili Lamp on children
- The effects of the Lili Screen on adults
Clinical study objectives
Led by Maria Pia Bucci's research team (CNRS / Robert-Debré University Hospital), the studies combined several assessment methods:
- Standardised speech and language assessments
- In-depth visual-attentional tests
- Eye-tracking analyses and voice recordings
A demanding double-blind methodology
Because Lili's light pulses are completely invisible to the naked eye, participants do not know whether the technology is switched on or off during the tests. This strict protocol ensures fully impartial results and scientifically rules out any placebo effect.
The study protocols are available on clinical trial registries:
ISRCTN21209189, ISRCTN14080164.
What the studies revealed
Measured with the technology on and off, on the same readers and the same texts.
Children and adults: an improvement measured on at least one reading criterion during the tests.
Adults: a third fewer letter-positioning errors, for clearer reading.
Adults: faster, smoother and more instinctive decoding across all the texts tested.
Children: direct access to meaning, beyond simple decoding. Comprehension almost doubled.
Children: much faster decoding of everyday words, freeing up energy for memorisation.
*Data from clinical studies conducted by a CNRS team at Robert-Debré Hospital with children and adults with dyslexia. Scientific papers are currently being published in a peer-reviewed journal. Every profile is unique, so results may vary from one person to another.
Disclaimer: Lili is a technology designed to optimise reading comfort. It is neither a medical device nor a therapeutic treatment. It was developed to support and complement speech therapy sessions or educational support, and never replaces them.
Our clinical studies are now complete. Their findings are being prepared for official publication in a peer-reviewed scientific journal, expected during 2026.
