Stellest lenses by Essilor use H.A.L.T. (Highly Aspherical Lenslet Target) technology to slow myopia progression in children — no contacts required. Learn how they work and whether your child is a candidate at ProVision Eye Associates in Blue Bell, PA.
What Are Stellest HALT Lenses?
Stellest lenses, developed by Essilor, are a revolutionary spectacle lens designed specifically to slow myopia (nearsightedness) progression in children. They use H.A.L.T. technology — Highly Aspherical Lenslet Target — a constellation of 1,021 invisible lenslets arranged across the lens surface that create a volume of light in front of the retina, signaling the eye to slow its growth.
At [ProVision Eye Associates](/services/myopia-control) in Blue Bell, PA, we are one of the few practices in Montgomery County offering Stellest as part of our comprehensive myopia management program.
The Science Behind H.A.L.T. Technology
Traditional single-vision spectacle lenses correct the central vision but allow peripheral light to focus behind the retina — a signal that the eye interprets as a cue to grow longer. Stellest's H.A.L.T. lenslets reverse this signal. Each of the 1,021 aspherical lenslets creates a point of light focus in front of the retina across the full peripheral visual field. This myopic defocus signal is present throughout the day whenever the child is wearing their glasses, continuously telling the eye to stop elongating.
Clinical Evidence for Stellest
The pivotal clinical trial for Stellest demonstrated a 67% reduction in myopia progression compared to standard single-vision lenses when worn at least 12 hours per day, and a 60% reduction in axial elongation. 9 out of 10 children showed slowed or halted myopia progression.
Who Is a Good Candidate for Stellest?
Stellest lenses are appropriate for children aged 6 years and older with progressing myopia. They are particularly well-suited for children who are not yet ready for contact lenses, children with significant astigmatism, and children who prefer glasses. The key requirement for maximum effectiveness is consistent wear — at least 12 hours per day.
Comparing Stellest to Other Myopia Control Options
| Treatment | Age Range | Wear Requirement | Contact Lens? |
|---|---|---|---|
| Stellest HALT | 6+ years | 12+ hrs/day glasses | No |
| MiSight 1 day | 8–12 years | Daily disposable CL | Yes |
| Ortho-K | All ages | Overnight CL | Yes (overnight) |
| Atropine drops | All ages | Nightly drop | No |
Many children use Stellest as their primary myopia control strategy during the early years (ages 6–9), then transition to [MiSight contact lenses](/blog/misight-contact-lenses-myopia-control-blue-bell-pa) or Ortho-K as they get older.
