MYOPIA CONTROL LENSES

Understanding myopia and why it progresses in children

Myopia, or nearsightedness, occurs when the eye grows too long from front to back. Light entering the eye focuses in front of the retina rather than directly on it, creating clear vision up close but blur at distance. In children, this isn't simply a focusing problem. It's a structural one.

Here's how we explain it to families in our practice: the length of your eyeball determines whether you're nearsighted or farsighted, assuming the cornea and lens have normal curvature. When children spend extended time doing near work like reading, using devices, looking at screens, light refracts behind the retinal plane. The retina essentially interprets this as a signal that the eye needs to keep growing to bring that light into focus. Over years of growth and development, this continuous elongation is what drives myopia progression.

This matters beyond just needing stronger glasses every year. Higher levels of myopia significantly increase the lifetime risk of serious eye diseases like retinal detachment, glaucoma, macular degeneration, and myopic maculopathy. We're not trying to alarm families, but we do believe in being clear: controlling myopia progression in childhood is about preserving long-term eye health, not just reducing prescription strength.

How myopia control lenses work

Traditional single vision lenses correct central vision but allow peripheral light to focus behind the retina, which research suggests continues to signal axial elongation. Myopia control lenses interrupt this signal.

DIMS (Defocus Incorporated Multiple Segments) and HAL (Highly Aspherical Lenslet) technologies work by creating multiple zones within the lens that simultaneously correct central vision while scattering peripheral light both in front of and behind the retinal plane. This removes the consistent elongation signal, slowing or halting the eye's growth response.

The results in clinical studies are meaningful. Essilor's Stellest lens, using HAL technology, has demonstrated approximately 70% reduction in myopia progression compared to standard single vision lenses. MiYOSMART lenses using DIMS technology have shown at least 60% reduction in progression. These are significant numbers, not marginal improvements.

Who should consider myopia control lenses?

We recommend myopia control lenses for any child showing consistent progression of their myopia over time. Children who would benefit most include those showing rapid progression, more than -0.50D per year, children whose parents have high myopia, and children who were diagnosed at a younger age, since earlier onset typically predicts higher lifetime myopia.

Myopia at lower levels is not cause for significant concern on its own. It's inconvenient but manageable. The goal of myopia control is to prevent progression into higher levels, typically above -6.00D, where retinal complications become meaningfully more likely and where options like LASIK become less predictable and refractive surgery for cataracts more complicated.

What parents can realistically expect

Myopia control lenses are not a cure and they do not reverse existing myopia. They are a tool to slow progression and the evidence suggests they work well. Full-time wear is important for maximum effect. Most families notice that prescription changes slow significantly compared to their child's previous rate of progression. Some children show near-complete stabilization.

Every myopia control order at Frame Republic is personally reviewed by one of our Doctors of Optometry before lenses are fabricated. We take this category seriously because the stakes for your child's long-term vision are real.
