Let’s be honest - screens are everywhere.
Between homework, gaming and FaceTime with family, devices are a significant part of life for Gen Zs and Alphas.
And while some headlines make it sound like screen time alone is causing an epidemic of myopia or shortsightedness, the truth is more nuanced.
It’s not just the screens - it’s the how
Myopia isn’t caused by screen use alone. Prolonged periods of near work—including reading, studying, and screen use has been a longstanding risk factor for myopia.
With digital devices now widely used for schoolwork and recreation, children are spending more time focusing on screens than traditional books.
“Viewing a screen is a more passive process than actively reading a book and it is very easy to be glued to screens for extended periods of time. The more time a child spends focusing up close - particularly if they are doing this inside - the higher the risk of developing myopia,” said Luke Arundel, Chief Clinical Officer at Optometry Australia.
That said, we’re not going to tell you to ban screens. That’s neither realistic nor helpful.
Instead, think about screen habits.
Smart strategies for screen-heavy families
Here’s how you can support your child’s eye health without going full digital detox:
- Prioritise regular eye exams with a trusted optometrist: kids should have their first comprehensive check-up the year they start primary school and then regularly as they progress through school.
- The 20-20-20 rule: Every 20 minutes, look at something 20 feet (about 6 metres) away for 20 seconds. This also helps relax the eye muscles and prevent eye strain and dry eye symptoms. Setting a timer can help!
- Encourage sun safe outdoor time: Aim for at least two hours a day. Natural light and distance viewing both help reduce myopia risk
- Watch the viewing distance: If your child is holding devices closer than 30 cm to their face, it’s time to step in. Remembering the “Elbow Rule” is particularly helpful.
- Set healthy screen routines: Have defined ‘no-screen’ times like during meals or the first hour after school.
- Ensure good lighting: Dim lighting increases eye strain. Make sure your child’s workspaces are bright and well set up.
Tech isn’t evil—it just needs balance
Screens aren’t going away. They’re part of how our kids learn, socialise and relax. But we need to make sure they’re not the only way our kids are engaging with the world.
“Balance is everything. If your child is using screens but also spending time outdoors, getting regular eye exams and using good viewing habits, you’re on the right track.”
Be screen-smart, not screen-scared. It’s not about guilt; it’s about giving your child’s eyes the best chance to thrive.
