Screen Time and Kids' Eyes

What Calgary parents should actually watch for as tablets, laptops, and classroom screens become part of everyday life.

In Short

Screens don't damage children's eyes long-term, but heavy near-focus use is linked to digital eye strain and faster progression of myopia (nearsightedness) in kids. The fix isn't banning screens, it's breaks, distance, and a yearly eye exam to catch changes early.

The Real Concern

It's not damage. It's distance.

Screens themselves don't cause permanent eye damage. The concern is how kids use them: long stretches of close-up focus, low blink rates, and less time spent looking at distant objects outdoors. That combination is associated with eye strain symptoms and, in the research on myopia, with a higher rate of nearsightedness developing or worsening in school-age children.

With more schoolwork happening on tablets and laptops, screen time isn't really optional anymore, which makes the habits around it, and regular eye exams, more important than trying to eliminate screens altogether.

Watch For

Signs of digital eye strain

  • Rubbing eyes or blinking a lot after screen use
  • Complaints of tired, sore, or dry eyes
  • Headaches that show up after homework or gaming
  • Holding devices unusually close to the face
  • Reduced interest in reading or near-focus tasks
Simple Habits

What actually helps

  • The 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds
  • Encourage time outdoors, linked to slower myopia progression
  • Keep screens at arm's length, not closer
  • Good lighting in the room to reduce glare and strain
Why an Exam Matters

Myopia can progress quietly. Exams catch it.

A child's prescription can change gradually enough that neither you nor they notice day to day. Annual eye exams for children under 19 are fully covered by Alberta Health Care, making it easy to track changes before they affect schoolwork or daily life.

What We Can Do

If screens are already affecting your child.

If your child is already showing signs of strain or a changing prescription, a comprehensive eye exam can confirm what's going on and whether options like myopia control are worth discussing. These are separate consults from a routine exam but start with the same simple first step, booking a checkup.

FAQ

Screen time and kids' eyes, answered.

Does screen time actually damage children's eyes?
Screens don't cause permanent damage on their own, but heavy near-focus use is linked to digital eye strain and, in research, to faster progression of myopia in some children.
How much screen time is too much for kids?
There's no single safe number, what matters more is breaks, distance from the screen, and balancing screen time with time spent outdoors and on distance vision.
Can an eye exam tell if screens are affecting my child?
Yes. A comprehensive eye exam can identify signs of eye strain and track any change in prescription over time, which is the clearest indicator of how screen habits are affecting your child's vision.
Is blue light from screens the main concern?
Not primarily. Current evidence points more to near-focus distance and reduced outdoor time as the bigger factors in digital eye strain and myopia progression than blue light itself.
