Stellest H.A.L. Lenses
A widely studied myopia control spectacle lens using Essilor's Highly Aspherical Lenslet technology, worn like ordinary glasses with no daily routine change.
A widely studied myopia control spectacle lens using Essilor's Highly Aspherical Lenslet technology, worn like ordinary glasses with no daily routine change.
Stellest was developed by Essilor following more than a decade of dedicated optical research into how peripheral defocus influences eye growth. Its H.A.L., Highly Aspherical Lenslet Target, design uses 11 concentric rings of tiny aspherical lenslets surrounding a clear central optical zone, creating a full volume of myopic defocus across the lens.
That continuous defocus signal is associated with slowing the underlying axial elongation responsible for progressing myopia, not simply correcting the blur it causes.
Eleven rings of tiny lenslets surround the clear centre, engineered from over a decade of optical research.
Aspherical lenslets arranged in rings around the clear central zone, delivering continuous myopic defocus.
The ring design covers more of the lens periphery than a segmented approach, for fuller coverage.
Built on more than ten years of dedicated Essilor optical research into peripheral defocus.
Consistent full-time wear, at least 12 hours a day, is associated with the strongest results in trial data.
The published two-year randomised trial remains one of the most cited in the myopia control field.
Stellest is designed to influence the underlying growth of the eye, and its effect is closely linked to how consistently it's worn.
The middle of the lens works just like a standard single-vision lens, giving your child sharp, clear eyesight for reading, the whiteboard and everyday life.
Eleven rings of tiny aspherical lenslets create continuous myopic defocus across the lens periphery.
Trial data found children wearing the lenses at least 12 hours a day saw meaningfully stronger results than less consistent wearers.
An average 50% reduction in progression, rising to 60% with consistent wear.
Available across a broad range of myopic prescriptions.
The lenslet rings are subtle and not noticeable at typical viewing distance.
A comfortable, needle-free, contact-lens-free option for children who prefer glasses.
Built on more than a decade of dedicated peripheral defocus research.
Clear, measurable improvement in results the more consistently it's worn.
We offer Stellest as a well-evidenced glasses option, and help every family build a wear routine that supports the strongest possible result.
We assess your child's progressing myopia and establish a baseline axial length measurement.
We fit each lens for optimal alignment and confirm frame suitability for the full ring pattern.
We review progress at regular intervals, tracking axial length, prescription change and wear consistency.
Book a comprehensive myopia assessment and we'll talk through Stellest and how it compares with our other treatment options for your child specifically.
Individual results vary by age, prescription and wear consistency. Stellest availability should be confirmed at consultation. This page is general information, not medical advice, please speak with one of our optometrists about whether Stellest is suitable for your child.
