Slow your child’s myopia — with evidence-based care

As soon as progression is documented. In practice, that’s usually between ages 6 and 12 — the window where progression is typically fastest and clinical benefit is greatest. Starting earlier gives the longest runway, but children diagnosed later still benefit from slowing remaining progression. The first step is a paediatric comprehensive exam with progression assessment; from there, your optometrist will recommend whether to start and which option fits best.

Neither is universally “better” — the right choice depends on the child. Soft myopia-control contact lenses (MiSight and similar dual-focus designs) report the largest effect sizes in the published literature, typically 40–60% progression reduction. Myopia-control spectacle lenses (MiYOSMART, Stellest) report 20–40% progression reduction and are often the better fit for younger children or children not yet ready for lens handling. Contacts require clean technique and compliance; spectacles do not. Prescription strength, progression rate, lifestyle, and family preference all factor into the recommendation. Your optometrist will walk through the trade-offs at the assessment.

Most children continue active treatment until myopia progression has stabilised, which usually happens in the mid-to-late teens. In practical terms, that means several years on a myopia-control lens, with 6- to 12-month follow-ups to track response. Some children can step down or stop earlier if progression slows; others continue longer. Your optometrist will reassess at each visit rather than committing to a fixed end date upfront.

OHIP covers one comprehensive eye exam every 12 months for children 19 and under, and medically necessary follow-up visits when indicated. OHIP does not cover myopia-controlling contact lenses, myopia-controlling spectacle lenses, or the lenses’ fitting fees — those are paid either out of pocket or through extended-health benefits. Most family extended-health plans reimburse eyewear and contact lenses, often on an annual allowance. We will verify your specific coverage and direct-bill wherever possible.

Screen time alone is not the single cause. The strongest predictor is genetics — a child with myopic parents has markedly higher risk. What screens (and other sustained near work) appear to do is accelerate progression once myopia begins, especially when near work displaces outdoor time. The evidence most consistent across studies is that two or more hours of daylight outdoor time per day has an independent protective effect, regardless of screen habits. So the practical message is less “cut screens” and more “protect outdoor time, keep reading distance normal, and take breaks.”

Low-dose atropine formulations (0.01%, 0.025%, 0.05%) were developed specifically to preserve efficacy while minimising the side-effect profile of historical higher doses. The ATOM2 study (Singapore, 2012) and the LAMP study (Hong Kong, 2019, 2022) and their follow-up literature report that low-dose atropine is generally well tolerated over multi-year courses. Side effects at 0.01% are typically mild — occasional light sensitivity or a slight reduction in near-focus comfort — and resolve when treatment is adjusted or stopped. As with any prescription, the UVG optometry team will review dosing, monitor response at follow-up visits, and adjust the protocol to your child’s progression and tolerance.

Standard single-vision glasses correct vision but do not slow progression. That’s why myopia-controlling lens designs exist — they intentionally redirect peripheral light to change the optical signal driving eye elongation. If your child is already in standard glasses and progression is steady, a conversation about switching to a myopia-controlling lens design — or adding low-dose atropine — is reasonable and is the most common starting point.

No. Myopia management is not a course that has to be completed without interruption — it’s ongoing monitoring with periodic treatment adjustments. A missed appointment does not undo previous benefit. That said, longer gaps reduce our ability to detect accelerated progression early, and a child who stops wearing the myopia-controlling lens will progress at the untreated rate again. Consistency matters; perfection does not.

The benchmark most studies converge on is two or more hours per day of daylight outdoor time. It does not need to be continuous — time before school, at recess, and after school adds up. Cloudy days still count; ambient daylight outdoors is far brighter than typical indoor lighting. Structured sports, walking to school, park time, and cycling all qualify. The protective mechanism appears linked to bright-light exposure, though the full biology is still being studied.

Higher myopia (typically ≥ -6.00 dioptres) carries elevated lifetime risk for retinal detachment, myopic macular degeneration, glaucoma, and early cataract. The risk rises with each additional dioptre. In childhood, the concrete warning signs that warrant a specialist look are: very rapid progression, visual acuity that cannot be corrected to normal, new floaters or flashes of light, or a “curtain” across part of the vision. Any of those should be assessed promptly. For routine monitoring of high myopia, annual dilated retinal examinations are the standard.

U Optical welcomes co-management with referring optometrists. Send the child’s refraction history, progression summary, and any axial-length data if available; we will see the family for assessment, share our findings and plan, and send you updates at every follow-up visit. Referrals can be sent via the U Vision Group referring-doctors portal at uptowneye.ca/referring-doctors, or contact U Optical directly at (416) 292-0336. Families self-refer by booking a myopia assessment — no physician referral required.
