Have you noticed your child squinting at the TV, or holding a book right against their nose? That's usually the first sign of nearsightedness. These days it's not just a glasses question — it's something we can actively slow down.
Myopia is rising fast worldwide. Projections suggest that by 2050, half the global population will be nearsighted. The good news: we now have a simple, safe tool that genuinely helps in childhood. Let me explain.
Why slow myopia at all
When a child becomes nearsighted, the eyeball grows longer than it should. Once it stretches beyond 26 millimetres, the retina (the back of the eye that receives the image) stretches with it.
In the long run, this raises the risk of serious adult eye disease — glaucoma (high pressure inside the eye), cataract (clouding of the lens), and retinal detachment. That's why the World Society of Paediatric Ophthalmology and Strabismus now recommends active myopia control, not just handing out glasses.
What the "magic drop" actually is
It's a simple eye drop containing atropine in a very low concentration. In large doses, atropine strongly dilates the pupils — that's what we use at the eye exam. In small doses (0.05%, 0.025% or 0.01%), it slows down excessive eyeball growth without disrupting daily life.
The Hong Kong LAMP study tested all three strengths in children over several years. The verdict was clear: 0.05% atropine works best — twice as effective as the 0.01% solution. One drop per eye before bed, every day. Simple.
Is it safe
Yes. Low-dose atropine is well tolerated in children. The most common side effect is mild light sensitivity in bright sunshine, because the pupils widen slightly.
The fix is easy: photochromic glasses — lenses that darken automatically outdoors. The drops don't affect reading or distance vision. Your child carries on with normal life.
The long game
Treating myopia is a marathon. If you stop the drops too early — especially while the child is still young — nearsightedness can speed up again. Doctors call this the rebound effect.
I recommend continuing the drops until your child is older and the eye's natural growth has slowed. We work out the exact plan together at the eye exam — every child is a little different.
What parents can do alongside
Outdoor time, every day. Natural daylight is one of the strongest known protective factors against myopia. Aim for at least 1–2 hours outdoors daily.
Breaks from close work. Every 30 minutes, 20 seconds of looking into the distance. Simple habit, real difference.
Sensible screen limits. Not to punish — just because too much close-up vision in a row puts unnecessary strain on the eye.
If you notice your child squinting or complaining about blurry vision, don't wait. Come in to KSA in Tallinn — the exam is quick and child-friendly. The earlier we start, the better the result.
