Myopia in Children: Why Is My Child's Glasses Power Increasing Every Year? (And How to Stop It)
A complete, science-based guide to myopia progression, atropine eye drops, and child eye care — from the pediatric ophthalmology team at Vedanta Netralaya, with eye care centres in Ghaziabad, Noida Extension (Greater Noida West), and Hapur.
Is your child's glasses number going up every visit? You are not alone.
Every few months you take your child for an eye check-up… and the glasses power increases again. Minus one becomes minus two, then minus three. As a parent, a quiet fear sets in — "Will my child go blind? Did the glasses spoil his eyes? Did we do something wrong?"
Take a deep breath. This rising number has a name — myopia progression — and today it is one of the most common reasons parents bring children to a pediatric ophthalmologist. The good news: while myopia cannot be reversed, modern child eye care has proven, scientific ways to slow it down. This guide explains exactly why the power increases, when it stops, and the treatments that actually work.
If your child's eye number keeps rising, you can book an eye doctor consultation at any of our three centres — Ghaziabad, Noida Extension (Greater Noida West), or Hapur — listed at the end of this article.
What is myopia, and why does the glasses power keep increasing?
Myopia (short-sightedness or nearsightedness) happens when the eyeball grows too long from front to back. Doctors call this axial length. When the eyeball becomes longer than it should, light focuses in front of the retina instead of on it — so distant objects look blurry, while near objects stay clear.
Here is the most important myth to clear up: glasses do not make myopia worse. The eyeball growing longer is what increases the number — the glasses simply help your child see clearly while that natural growth happens.
How much growth are we talking about? In a normal eye, the eyeball grows only about 0.1 mm per year and settles down by the pre-teen years. In a myopic eye, it grows faster — often 0.2 to 0.3 mm every year — and continues growing for many more years. That tiny extra growth, repeated year after year, is exactly why the glasses power keeps climbing. This is myopia progression, and catching it early is the heart of good child eye care.
When will my child's eye number finally stabilise?
This is the question every parent asks our pediatric ophthalmologist team. The honest, research-based answer comes from a major long-term study (the COMET study):
- On average, myopia begins to stabilise around age 15 to 16.
- In some children, the number can keep changing right up to about age 24.
- At around age 15, roughly half of children have stopped progressing — the rest are still going.
There is one crucial warning from the science: the younger the child is when myopia starts, the higher the final number tends to be. Children who become short-sighted before age eight are at the highest risk of reaching very high myopia. This is precisely why our advice is never to "just keep changing glasses" — it is to start myopia control early under the guidance of an eye specialist.
What causes myopia in children?
Myopia is driven by a mix of two things:
- Genetics. If one or both parents wear glasses for distance, the child's risk is higher.
- Lifestyle — the part we can change. Excessive near work, high screen time, and especially too little time outdoors in daylight all push the eyeball to keep stretching.
In short, genetics loads the gun, but lifestyle pulls the trigger. That is actually empowering news for parents, because it means your daily choices have real influence over your child's eye health.
Can myopia be reversed? The honest truth
Let us be completely honest: there is no cure that reverses myopia. Once the eyeball has grown longer, it cannot shrink back, so no eye drop, tablet, or exercise can erase an existing number. Be very cautious of anyone — or any "ayurvedic eye drop" — that promises to reduce the number. Unproven drops can even harm a child's eyes.
But this does not mean you are helpless. Science has given us three proven ways to slow myopia progression. Let's look at each.
Proven Treatment #1: Low-dose Atropine eye drops
The first scientifically proven treatment is a prescription medicine called atropine eye drops, used in a very low concentration. This is completely different from herbal or over-the-counter drops, and must always be prescribed and monitored by an eye doctor.
How do atropine eye drops work? They send a "slow down" signal to the eye, reducing how fast the eyeball lengthens. Atropine does not reverse the number — it slows the future increase.
Which concentration? The landmark LAMP study (Low-Concentration Atropine for Myopia Progression) compared 0.05%, 0.025%, and 0.01% atropine. Over three years, 0.05% atropine was the most effective — more than double the effect of 0.01%. So while 0.01% is the gentlest dose, current evidence often favours 0.05% for stronger control. Your pediatric ophthalmologist chooses the right strength for your child.
At what age? Atropine eye drops are generally used in children roughly between 5 and 18 years of age, placed in the eye once at night, at bedtime.
For how long? Not weeks — usually a minimum of two to three years, and often longer, continuing until myopia naturally stabilises in the late teens.
The rebound effect — why you should never stop suddenly. Studies show that stopping atropine too early — especially in younger children — can cause myopia to speed up again (a "rebound"). The rebound is larger with higher doses and younger age at stopping. That is why the modern approach is to continue treatment patiently and simply restart the drops if progression returns. Start under medical guidance, continue steadily, and stop only when your eye doctor confirms the eye has stabilised.
If you want to know whether atropine eye drops are suitable for your child, this is exactly the kind of decision our specialists handle during an eye doctor consultation.
Proven Treatment #2: Outdoor time and daylight (and it's free!)
The second proven method costs nothing — outdoor time in daylight.
The research is striking. A famous trial in Guangzhou, China showed that just 40 extra minutes of outdoor time cut new myopia cases by nearly 25% over three years. Another study in Taiwan found that around 80 minutes a day could cut new cases by roughly half.
How much does my child need? The research target is at least 2 hours every day outdoors — and more is better.
Which sport or game is best? Here is the surprising part: it is not the type of exercise that matters most — it is the bright outdoor light. So any outdoor activity in daylight counts: cricket, football, cycling, badminton, running, skipping — even walking or a picnic. What matters is the daylight and looking at distant objects.
One honest point: outdoor time is most powerful at preventing myopia from starting. For a child who already wears glasses, it helps a little less — but it still protects overall eye health, body, and mind. So please, send your children outside every single day.
Proven Treatment #3: Myopia-control glasses (MyoCare)
The third proven option is special myopia-control glasses — not ordinary spectacles. A modern example is the MyoCare lens.
The technology. A normal lens only corrects vision. A MyoCare lens has a clear central zone for sharp vision, surrounded by a special zone of tiny microscopic structures called C.A.R.E. technology (Cylindrical Annular Refractive Elements). These create "competing defocus" that signals the back of the eye to slow its growth — an idea inspired by the ring-shaped pattern left after orthokeratology.
It is age-related. There are two versions: MyoCare for children under 10 years (smaller 7 mm clear zone) and MyoCare S for children 10 years and older (larger 9 mm clear zone), matched to how a child's vision behaviour changes with age.
Who can wear it? In clinical trials, MyoCare was used in children roughly 6 to 13 years old, with numbers between about −0.75 and −5.00. The lenses are worn full-time, like normal glasses, and continued until myopia stabilises in the late teens.
Does it work? Yes — and across continents. Trials showed children wearing MyoCare lenses had eye growth slowed close to that of a normal, non-myopic eye, and reduced fast myopia progression by up to 3.5 times compared with ordinary glasses, with benefits confirmed in both Asian and European children.
Common myths about children's glasses — busted
- "Once he wears glasses, he'll need them forever." The glasses didn't trap his eyes — the eye already needed correction. They simply help him see.
- "The number rises because of wearing glasses continuously." False. Giving a weaker number (under-correction) does not slow myopia — research shows it only strains the eyes.
- "Ayurvedic eye drops will reduce the number." No drop can reduce an existing number, because the eyeball cannot shrink back.
- "A tablet will cure it." There is no tablet that cures myopia.
- "Glasses only for reading, or all day?" For a short-sighted child, science is clear — wear them full time, all day. Repeatedly removing them tires the eyes and does not slow the number.
The one thing every parent should do
Don't chase a cure. Start myopia control early — because the earlier you act, the lower your child's final glasses power is likely to be.
Visit a qualified pediatric ophthalmologist, get a proper check-up (including axial length measurement if available), and ask: "Is my child suitable for myopia control treatment?" That single question can protect your child's vision for life. Even after the number stabilises, regular eye check-ups remain important, because higher myopia carries lifelong risks to the retina.
