Myopia in children: why slowing it early pays off
Last updated: 20 August 2026
More and more children are becoming near-sighted, at ever younger ages. That's more than a glasses matter: the younger myopia starts, the higher the final prescription tends to be — and high myopia raises the risk of eye conditions in adulthood. The good news: progression can now be slowed, and parents can help too.
In short
- Childhood myopia is rising sharply, and early-onset myopia tends to progress further.
- Outdoor time demonstrably helps: aim for about two hours of daylight per day.
- Progression can be slowed with special spectacle lenses, contact lenses or (via an ophthalmologist) eye drops.
- Squinting, sitting close to screens, or trouble following school? Have the eyes measured — checking young pays off.

What is going on with myopia in children?
Myopia develops when the eye grows slightly too long: distance becomes blurry. It usually starts between ages 6 and 14 and progresses while the eye grows. Worldwide the share of myopic children is rising fast — more near work and less outdoor time play a part.
Why does it matter? Every added dioptre increases the later-life risk of conditions such as retinal detachment and myopic macular problems. Not a reason for fear — but a real reason to take progression seriously now that it can be influenced.
What can parents do themselves?
The best-supported advice is surprisingly simple: outdoor time. Around two hours of daylight per day demonstrably slows the onset of myopia. Also sensible: alternating near work (look up and into the distance after 20–30 minutes), sufficient reading distance (forearm length), and no screens right before sleep.
And: have your child's eyes measured when you notice signs — squinting, creeping close to the TV or tablet, headaches, or trouble reading the board at school. Children rarely complain themselves; they don't know any better.
Which treatments slow progression?
Three evidence-based routes exist, all via a (paediatric) optometrist, orthoptist or ophthalmologist. Special spectacle lenses with a control design look like normal glasses but slow eye growth. Special contact lenses do the same — as daytime soft lenses or as overnight lenses (ortho-K) that temporarily remodel the cornea at night. And via an ophthalmologist there are low-dose atropine drops. What fits depends on age, prescription, motivation and lifestyle — and the effect is largest when you start early.
Ordinary glasses correct vision but do not slow progression. So ask about control options actively if your child's prescription climbs every year.
When should you act?
At the first signs of blurry distance vision, when a prescription keeps climbing yearly, and in any case around ages 6 and 12 when myopia runs in the family — children of myopic parents carry elevated risk. There are plenty of measuring moments: optician, optometrist or youth healthcare. What matters most is following the trend, not a single loose measurement.
Frequently asked questions
My child has -1. Is that bad?
A single measurement mainly describes today. The pace matters more: if half a dioptre to a dioptre is added yearly, that is the conversation worth having — precisely because slowing it then yields the most.
Does less screen time really help?
The honest answer: outdoor time has stronger evidence than screen time as such. Screens usually mean lots of near work and less time outside — address those two and you automatically address the screen effect.
Are overnight lenses (ortho-K) safe for children?
In experienced hands and with good hygiene, ortho-K is an accepted control option. The key requirement is discipline in cleaning and keeping up the check-ups — discuss with the specialist whether that fits your family.
