Essilor will unveil pivotal 2-year clinical trial results of its Stellest lens for myopia. The 2-year results demonstrate that Essilor Stellest lenses slow down myopia progression by 67% on average, when compared to single vision lenses, when worn at least 12 hours a day,1 according to Essilor.
The presentation of the research, entitled “Myopia control with spectacle lenses with aspherical lenslets: a 2-year randomized clinical trial,” will be delivered at the annual meeting of the ARVO, on May 6, 2021, by BAO Jinhua,2 Associate Professor at Wenzhou Medical University, China.
In 2018, Essilor’s research and development team initiated a 3-year clinical trial on 167 myopic children3 in its joint Research and Development Center shared with key partner, the Wenzhou Medical University, in China.
Key outcomes include:
● After 2 years, children wearing Essilor Stellest lenses saved 0.99 diopters of myopia degree on average (67% slow-down in myopia progression on average), compared to single vision lenses, when worn 12 hours or more per day every day.
● After the first year, the eye growth of 9 out of 10 children wearing Essilor Stellest lenses was similar or slower than non-myopic children.1
● Two out of 3 children who wore Essilor Stellest lenses did not need a prescription change after the first year1.
● 100% of children wearing Essilor Stellest lenses had clear vision, 100% of children adapted to their new lenses within a week; 91% of children fully adapted within three days; and 94% of children felt comfortable with Essilor Stellest lenses, demonstrating that Essilor Stellest lenses were comfortable, and easy to adapt for children.1
“With such impressive results, Essilor’s Stellest lenses will truly be a catalyst to stem myopia progression and to help children, who continue to be at risk of sight-threatening eye conditions associated with myopia,” Norbert Gorny, Co-Chief Operating Officer, Essilor International, said in a company news release. “Essilor is proud to be at the forefront of myopia management and we will continue to be focused on bringing such innovative advances to move the needle on the fight against myopia.”
The Essilor Stellest lenses provide myopia correction through a single vision lens, which allows for sharp far vision and myopia control through H.A.L.T.4 technology, which consists of a constellation of aspherical lenslets spread on 11 rings and was designed to create for the first time, a volume of signal that slows down the elongation of the eye. The power of lens lets on each ring has been determined to guarantee a volume of signal always in front of the retina and following its shape, to achieve consistent myopia slowdown.

Two-year prospective, controlled, randomized, double-masked clinical trial results – 104 myopic children split in two groups: Single vision lenses (50) and Essilor Stellest™ lenses (54) – Efficacy results are based on 32 children who declared wearing Essilor Stellest™ lenses at least 12 hours per day every day – Eye Hospital of the Wenzhou Medical University – J.
