What are Stellest lenses?
Stellest lenses are spectacle lenses (glasses) made by Essilor, designed not just to correct nearsightedness (myopia) — but to slow its progression over time.
The “magic” comes from a technology called Highly Aspherical Lenslet Target (HALT): the lens combines a central single-vision zone (for clear everyday vision) with a surrounding “treatment” zone full of tiny aspherical lenslets.
These lenslets create a controlled pattern of light known as a “volume of myopic defocus” — effectively sending a signal to the eye to slow down its growth (which is what causes worsening myopia).
📈 Evidence: How Effective Are They
Clinical studies show Stellest lenses significantly slow myopia progression and axial elongation (the physical lengthening of the eye) compared with standard single-vision lenses.
In one 6-year follow-up study, children/adolescents who wore HALT lenses had a mean change of –1.50 diopters of refractive error compared to –3.45 diopters in an extrapolated control group — a reduction of about 57%.
In that same study the axial elongation (eye growth) was nearly half: 0.76 mm in the HALT group vs. 1.57 mm in the control — roughly a 52% slowdown in eye growth.
In shorter-term clinical trials (2 to 3 years), reductions of ~67 % in myopia progression (vs single-vision lenses) have been reported when the lenses are worn consistently (often defined as ≥12 hours/day) by children.
