The Lili screen, a 27-inch monitor that integrates modulated light technology intended to stabilize visual perception and reduce reading effort for dyslexic users.
The company says the product is aimed primarily at adults in professional environments, though it will also be available to consumers through Amazon.
The technology behind the screen is based on research by French physicists Albert Le Floch and Guy Ropars.
“They have found out that dyslexic people have a sort of non-dominance in the eyes,” Bertrand Descours, co-founder of Lili for Life, told The Vertical in an interview. “Both eyes are bringing information at the same time to the brain, and that causes confusion in words and letters.”
According to Descours, this can result in unstable visual perception, making reading more difficult and tiring.
Using a calibrated flickering light — adjusted to the individual user — the screen introduces a slight timing offset between the visual input from each eye.
“With specific flickering light, we can create a sort of time lapse between the two eyes,” Descours said. “Once you have done this, the perturbation in reading is cleared. You can concentrate on comprehension and understanding.”
The Lili screen was finalized in 2025 after two years of development and a year of testing with employees at several large French companies.
Clinical surveys were also conducted in France in collaboration with a Paris hospital, using what Descours described as blind tests in which 40 participants did not know whether the system was active.
The company measured reading comprehension rather than speed alone, Descours said. “For adults, it’s a plus 30% of understanding,” he said. “For kids, it’s more than 50%.”
The tests compared comprehension results using texts of similar complexity, with and without the technology activated.
Individual experiences vary, Descours said. Some users report that their eyes “stick to the line,” while others say they gain a wider visual field that allows them to anticipate upcoming words and read more fluently.
The LILI Screen follows an earlier product, the Lili lamp, which applies the same modulated light principle to printed materials. The lamp has been available on Amazon in the U.S. since November 2025 and has already been deployed in a pilot program at Rock Springs Elementary School in Kingsport, Tennessee.
Although most monitors are manufactured in Asia, Descours said the Lili screen is transformed and assembled in France, near Toulouse, with proprietary electronics added there.
Lili for Life holds patents covering the technology across major global regions, including North America, Europe and Asia, according to Descours. The patents were developed in collaboration with the researchers behind the original scientific work.
With its U.S. launch approaching, the company is now testing whether a technology born in a French physics lab can find a broader role in offices across the Atlantic.
