If your child's glasses prescription has been getting stronger every year, you're witnessing myopia progression — and it's more than just an inconvenience. High myopia carries real long-term health risks including increased lifetime rates of retinal detachment, glaucoma, cataracts, and myopic macular degeneration. The time to intervene is during childhood, while the eye is still growing. And among the available tools, orthokeratology stands out as one of the most effective and elegant solutions we have.
Why Ortho-K Slows Myopia Progression
Myopia progresses because the eye continues to elongate — growing longer from front to back — which shifts the focal point in front of the retina rather than directly on it. This elongation is partially driven by a signal from the peripheral retina. When a conventional lens corrects central vision but leaves peripheral vision in a state of hyperopic defocus (focused behind the retina), it actually stimulates further eye elongation.
Ortho-K lenses reshape the cornea in a way that corrects central vision while simultaneously creating myopic defocus in the peripheral retina — precisely the opposite signal. This peripheral defocus tells the eye to slow its elongation. Clinical studies consistently show that Ortho-K reduces axial elongation (eye growth) by 30–60% compared to conventional glasses or soft contact lenses. For a child who might otherwise progress from -2.00 to -6.00 over a decade, that difference is significant.
The Dual Benefit: Vision and Control
What makes Ortho-K particularly appealing for families is that it delivers two benefits simultaneously. Your child wears the lenses while sleeping and wakes up with clear vision — no glasses, no daytime lenses. They can play sports, swim, attend school, and go about their day with natural uncorrected vision. And while they're experiencing that freedom, the lenses are also doing the critical work of slowing their myopia progression.
Compare that to conventional glasses, which correct the prescription but do nothing to slow its increase — or even potentially accelerate it through peripheral hyperopic defocus.
Is My Child a Candidate?
Ortho-K is appropriate for most children with mild to moderate myopia, typically starting as young as age 6–8. Children are often better candidates than adults because they tend to adapt to lens insertion and removal quickly and are highly motivated by the prospect of glasses-free days. The process requires parental involvement in the early weeks — supervising lens insertion and removal — which most families find manageable.
At Harnos Optometry in New Paltz, we'll perform a full evaluation including corneal topography to determine whether your child is a good candidate and what results to expect. If myopia control is a priority for your family, let's talk — call or text us at (845) 255-4696 to schedule a consultation.
