If your child is short-sighted, the glasses we prescribe are no longer just about making the blur go away. At Rose Optometry in Hamilton we now treat progressing childhood myopia as a condition to be managed, not simply corrected — and that change is the reason we no longer fit standard single-vision glasses for a progressing myopic child.
Why single vision is no longer our default for children
A single-vision lens sharpens vision. It does nothing to slow the underlying problem: the eye growing too long. And the length of the eye is what determines lifetime risk.
The evidence here is not marginal. In a meta-analysis of myopia complications, even low myopia carried a meaningfully raised risk of myopic macular degeneration and retinal detachment, and the risks climb steeply with degree — for high myopia the odds of myopic macular degeneration were dramatically higher than in non-myopic eyes, alongside increased risk of retinal detachment, cataract and glaucoma (Haarman et al., Investigative Ophthalmology & Visual Science, 2020). Importantly, the authors concluded that low and moderate myopia also carry considerable risk — there is no “safe” amount of progression to be relaxed about.
Every dioptre we prevent, and every fraction of a millimetre of axial elongation we avoid, is risk removed from your child’s sixth, seventh and eighth decade. A single-vision lens removes none of it. That is the whole argument.
What actually slows myopia — the evidence
Multiple treatment classes now have randomised-trial support, all measured against single-vision spectacles as the comparator:
- Myopia control spectacle lenses (defocus and lenslet designs — e.g. MiYOSMART/DIMS, HAL). In a two-year double-masked randomised trial, highly aspherical lenslet lenses slowed refractive progression by 0.80 D and axial elongation by 0.35 mm versus single-vision lenses — with better results in children who wore them at least 12 hours a day (Bao et al., JAMA Ophthalmology, 2022).
- Orthokeratology (overnight lenses that reshape the cornea — our Shift lenses). Network meta-analysis places ortho-K among the effective interventions for slowing axial elongation (Huang et al., Ophthalmology, 2016). The child also spends the day free of glasses and contact lenses.
- Dual-focus soft contact lenses (e.g. MiSight 1 day). Effective for axial control, and children adapt readily: across a six-year study, satisfaction with comfort and vision stayed above 93% and wearing time increased over time (Lumb et al., Contact Lens & Anterior Eye, 2023).
- Low-dose atropine eye drops. Atropine has the strongest effect on refractive progression of the classes studied, and low concentrations (0.01–0.05%) give significant efficacy with minimal side effects (Huang et al., 2016; Vagge et al., Journal of Clinical Medicine, 2026).
- Combination therapy. Where a single treatment isn’t holding progression, combining optical and pharmacological approaches adds benefit — a European study found DIMS spectacles combined with atropine outperformed either alone on refractive progression (Nucci et al., PLOS ONE, 2023).
- Time outdoors remains genuinely protective against myopia developing in the first place, and is free.
How we manage it at Rose Optometry
Modern myopia management is not a product — it’s a monitoring relationship. We measure axial length, not just the spectacle prescription, because axial length is the variable tied to future disease. We plot your child against age-expected growth, set a target, review at defined intervals, and escalate treatment if progression outruns the plan. Choice of treatment depends on the child’s age, rate of progression, prescription, lifestyle and how they’ll realistically manage lenses or drops — which is exactly what the free myopia chat is for.
This approach — risk stratification by axial length, age-specific growth targets and structured longitudinal monitoring — is what the current evidence review describes as the standard of care, with the goal being not merely slower progression but the prevention of high myopia and the lifetime burden that comes with it (Vagge et al., 2026).

What this means for parents
If we’ve told you we won’t simply re-prescribe single-vision glasses for your child, this is why. We are not selling you an upgrade; we are declining to do something we no longer believe is adequate care for a growing myopic eye. Adults with stable prescriptions are a different matter entirely — single-vision lenses remain completely appropriate there.
