Kids and Screens: A Parent's Guide to Preventing Myopia in Children

Your child squints at the board. Sits too close to the TV. Holds the phone three inches from their face. You think - maybe they just need glasses.

You're probably right. But there's more to it than a new prescription.

Myopia - short-sightedness - is one of the fastest-growing childhood health concerns in India today. And screens are only part of the story. This guide is for every parent who wants to understand what's actually happening to their child's eyes, what they can do about it, and when it's time to see an eye specialist in Siliguri.

What Is Myopia - and Why Are So Many Children Getting It?

Myopia is when the eye grows slightly too long. Light focuses in front of the retina instead of directly on it - which means distant objects look blurry, but close ones are clear.

It typically starts between the ages of 6 and 14. And once it starts, it tends to progress - sometimes quickly - until the late teens or early twenties.

In India, myopia rates in children have been rising steadily for years. The reasons are a combination of genetics, lifestyle, and environment:

• More time indoors- Less exposure to natural daylight
• More near work- Reading, screens, tablets, and phones for hours at a stretch
• Family history- If one parent is myopic, the risk doubles; if both are, it's significantly higher
• Less outdoor play- Research has proven over and over again that kids who spend more time outside are less prone to developing myopia.

The screens aren't helping. But they're not the whole story either.

Signs Your Child Might Have Myopia

Children don't always tell you their vision is blurry. Often they've never known anything different - so they assume everyone sees the world the same way they do.

Watch for these signs:

• Squinting to see the board at school or the TV at home
• Sitting unusually close to screens or holding books very close
• Frequent headaches - especially after school or extended reading
• Rubbing eyes often
• Complaints that the board is "hard to read" or "too far"
• Losing interest in outdoor activities that require distance vision
• Blinking a lot

If you notice any of these - especially in a school-going child - it's time to get their eyes properly tested. Not just a quick vision chart at school. A proper examination at a good eye clinic in Siliguri.

Myopia at a Glance

The Real Risk Parents Often Miss

A glasses prescription fixes how your child sees today. But myopia management is about controlling how fast it gets worse.

High myopia - Prescriptions of more than - 6.00D - poses significant dangers to one’s eyesight in the long run. The risk of suffering from retinal detachment, glaucoma, cataracts and other serious eye diseases is much higher for such prescriptions. The aggressive management of myopia during childhood helps avoid that.

This is the part most parents aren't told at the optical shop. A higher number every year isn't just "normal childhood myopia." It's a progression that can and should be managed.

How Myopia Is Diagnosed - What the Tests Actually Mean

A proper myopia evaluation is not just reading letters off a chart. At a dedicated myopia clinic, the assessment includes:

Cycloplegic Refraction- eye drops are used to relax the eye's focusing muscles before measuring the prescription. This gives a far more accurate reading than a standard vision test, especially in children whose eyes compensate naturally.

Axial Length Measurement (Optical Biometry) - this measures the physical length of the eyeball. Since myopia is caused by the eye growing too long, tracking axial length over time is the most accurate way to monitor whether myopia is progressing - and how fast.

Corneal Topography (Pentacam) - maps the shape and curvature of the cornea in precise detail. Essential for contact lens fitting and for evaluating whether the child is a candidate for certain myopia control treatments.

Retina Check-Up - examines the retina for any early changes associated with high myopia.

Binocular Single Vision (BSV) Assessment - checks how both eyes work together.

This level of evaluation gives our ophthalmologists in Siliguri the full picture - not just today's prescription, but the trajectory of the child's myopia and the most appropriate management approach.

Myopia Treatment Options for Children

There's no single treatment that works for every child. The right approach depends on age, prescription, rate of progression, and lifestyle. Here's what's available:

Spectacles (Glasses)

The first step for most children. Standard single-vision glasses correct vision but don't slow progression. Certain specialised lenses - like myopia control glasses - are designed to slow axial length growth and are worth discussing with your ophthalmologist.

Contact Lenses

For older children and teenagers, soft contact lenses or specialised myopia control contact lenses can be prescribed. Our contact lens clinic trains children and parents in safe lens care - which is essential to avoid the infection risks that come with incorrect use.

At The Himalayan Eye Institute, our senior optometrist trained in contact lens procedures prescribes high-quality silicone hydrogel soft lenses - the same type worn by Kumar Aryan, a 17-year-old from Siliguri who was selected in the Kolkata Striker team for a Junior IPL event in Dubai. Wearing glasses was a barrier to his cricket - contact lenses gave him back his game. He took 5 wickets in Dubai wearing them.

Orthokeratology (Ortho-K)

Specially designed rigid lenses worn overnight that gently reshape the cornea while sleeping. The child wakes up and can see clearly through the day without any lenses. Strong evidence supports Ortho-K for slowing myopia progression in children.

Low-Dose Atropine Eye Drops

A very dilute concentration of atropine applied nightly has been shown in multiple large studies to significantly slow myopia progression in children. It's one of the most evidence-backed myopia control options available. Your ophthalmologist can advise whether it's appropriate for your child.

LASIK and Refractive Surgery

Not suitable for children or teenagers - the prescription needs to be stable for at least a year, which usually happens in the early-to-mid twenties. LASIK remains an excellent option for young adults once myopia has stabilised.

The One Thing That Actually Helps - and It's Free

Research consistently shows that children who spend more time outdoors develop myopia less often - and when they do develop it, it progresses more slowly.

Two hours of outdoor time per day appears to make a meaningful difference. The reason? Natural daylight plays a role in healthy eye development. It's not about the distance you're looking at - it's about the quality of light your eyes are receiving.

This doesn't mean screen time causes myopia directly. But less outdoor time almost certainly makes things worse.

So before you add another screen restriction app - add outdoor time. Every day. It's the most underestimated tool in myopia prevention.

Practical Tips for Parents

Limit continuous near work. Every 20 minutes of close work - reading, screens, drawing - encourage 20 seconds of looking at something 20 feet away. This is called the 20-20-20 rule, and it helps reduce eye strain.

Maintain distance from screens. The recommended distance from a tablet or phone is at least 30–40 cm. A laptop should be at arm's length. The TV should be at least 2–3 metres away.

Proper lighting matters. Reading or studying in dim light is uncomfortable and increases eye strain. Good ambient lighting reduces the effort the eye has to make.

Watch the posture. Children who read or use devices lying down, at odd angles, or with the screen too close are making their eyes work harder than they need to.

Annual eye check-ups. Once a child starts school, annual eye examinations are important - regardless of whether you've noticed any symptoms. Many myopic children never complain because they don't realise their vision is different from everyone else's.

When Should Your Child See an Eye Doctor?

Book an appointment if:

• Your child is squinting at the board or TV
• Teachers have mentioned your child seems to be struggling to see
• Your child holds books or devices very close
• Headaches are frequent - especially after school
• It's been more than a year since the last eye check-up
• Your child has a parent or sibling with myopia

The earlier, the better. Myopia that's identified and managed at -1.00 D is far easier to control than myopia that's reached - 4.00 D because it went unnoticed for years.

80% of what a child learns happens through their eyes. That makes your child's vision one of the most important things you can take care of - and one of the most rewarding to protect.

Frequently Asked Questions About Myopia in Children

Q1. What is myopia and why is it so common in children today?

Myopia occurs when the eye grows too long, resulting in a blurring of far-off things. It usually begins between the ages of six and 14 and has become extremely common amongst children globally, owing to the fact that more kids are spending time indoors and not enough time outside.

Q2. Can myopia be cured in children?

However, it is impossible to cure myopia using the traditional way since it is not possible to shorten the eyes. However, there are corrective measures such as wearing glasses or lenses. The other method that can slow down the development of myopia is through myopia control which includes lenses, orthokeratology, and low dose atropine.

Q3. Does screen time cause myopia?

However, excessive exposure to screens is not what causes myopia, but rather the loss of outdoor activity as a result of excessive exposure to screens. Exposure to daylight is vital for proper visual development. It is more important to regulate near activity and ensure enough time spent outside than to limit screen time.

Q4. Is myopia hereditary?

Yes - family history is one of the strongest risk factors. If one parent is myopic, a child's risk roughly doubles. If both parents are myopic, the risk is significantly higher. Children with myopic parents should have regular eye checks even if no symptoms are apparent.

Q5. How much outdoor time actually helps with myopia?

Around two hours a day seems to be the figure that comes up consistently in research. Not two hours of sport necessarily - just being outside in natural daylight. It won't reverse myopia once it's started, but it appears to meaningfully slow the rate at which it develops and progresses. For parents of young children who haven't developed myopia yet - this is the single most practical thing you can do right now, for free, starting today.
