Screen Time and Your Child's Eyes: What Auburn Bay Parents Should Know

Screens have become a part of everyday life, from homework, to entertainment, and even social time. But as screen use increases, so do concerns about how it’s affecting children’s vision.

If you’ve noticed your child rubbing their eyes, complaining of headaches, or struggling to focus after screen time, you’re not alone. The good news? There are simple, effective ways to protect your child’s eyes without eliminating screens entirely.

The 20-20-20 Rule (And Why It Matters)

One of the easiest ways to reduce digital eye strain is the 20-20-20 rule:

• Every 20 minutes

• Look at something 20 feet away

• For at least 20 seconds

  
  

When kids focus on screens for long periods, their eyes stay locked in a near position. This can lead to fatigue, dryness, and difficulty refocusing. Encouraging regular breaks helps relax the eye muscles and reduces strain, especially during homework or gaming sessions.

How Screen Time Can Contribute to Myopia

Myopia (nearsightedness) is becoming increasingly common in children and excessive near work is a major factor.

Near work includes:

• Screen use (tablets, phones, computers)

• Reading or homework

• Any activity done up close for long periods

  
  

When the eyes are constantly focusing up close, it can signal the eye to grow longer over time, leading to worsening myopia. This problem isn’t exclusive to screen use. Even activities like reading or writing require this type of near vision focus. 

Even more important? Kids today are spending less time outdoors, which plays a protective role in healthy eye development.

Screen Time Guides By Age

The Canadian Paediatric Society provides helpful recommendations for screen use:

• Under 2 years: Avoid screen time (except video calls)

• Ages 2–5: Limit to 1 hour per day

• Ages 5+: Focus on consistent limits and healthy habits

  
  

Rather than aiming for perfection, the goal is balance. The idea is to ensure that screen time doesn’t replace sleep, physical activity, or outdoor play.

Practical Tips for Calgary Parents

Living in Calgary can mean long winters and unpredictable weather, but eye health habits can still be built year-round.

1. Prioritize Outdoor Time (Even in Winter)

Spending time outdoors has been shown to slow myopia progression. Aim for at least 2 hours per day when possible. Even in winter, daylight exposure matters, so bundle up and get outside when you can.

2. Improve Lighting at Home

Avoid using screens in dark rooms. Good lighting reduces strain and helps your child maintain a more natural visual posture.

3. Watch Viewing Distance

A simple rule:

• Screens should be about arm’s length away

• Books should sit at least 30–40 cm (12–16 inches) from the eyes

If your child constantly moves closer, it may be a sign of a vision issue.

4. Build Breaks Into Routines

Instead of reminding your child constantly, tie breaks to habits:

• After each level of a game

• Between homework tasks

• During TV episodes

When Screen Symptoms Mean It's Time for an Eye Exam

Some symptoms go beyond normal screen fatigue and shouldn’t be ignored.

Book an eye exam if your child experiences:

• Frequent headaches

• Blurry vision (near or distance)

• Eye strain or tired eyes

• Double vision

• Difficulty concentrating

• Holding screens very close

  
  

These may be signs of underlying vision issues and not just “too much screen time.”

Supporting Your Child With Myopia Control

If your child is developing or already has myopia, early intervention matters. We offer advanced lens options designed to help manage myopia progression, including Essilor Stellest™ lenses. These lenses are specifically engineered to not only correct vision, but also help slow the progression of nearsightedness in children.

Unlike standard glasses, Stellest lenses use specialized optical technology to reduce the signals that contribute to eye elongation, which is one of the key factors in worsening myopia.

This means your child can:

• See clearly day-to-day

• Potentially slow the progression of their prescription over time

• Support better long-term eye health

  
  

Managing myopia is not only about having clearer vision today, it’s about protecting your child’s vision and eye health for the future.

The Bottom Line

Screens aren’t going anywhere and they don’t have to. With the right habits, you can help protect your child’s vision while still allowing them to learn and enjoy technology.

Making small changes like encouraging breaks, increasing outdoor time, and watching for symptoms can make a big difference.

If you have concerns about your child’s vision or screen habits, booking an eye exam is a great next step. Early support leads to better outcomes and healthier eyes for the future!

Frequently Asked Questions

Can screen time actually cause myopia (nearsightedness)?

Screen time itself isn’t the only cause, but prolonged near work (including screens, reading, and homework) is strongly linked to myopia progression. Combined with low outdoor time, it can increase the risk of developing or worsening nearsightedness.

Does outdoor time really make a difference?

Yes, studies show that spending time outdoors can help reduce the risk of myopia progression. Natural light and focusing at different distances both play a role. Aim for around 2 hours a day when possible, even during Calgary’s colder months.

What are signs my child is experiencing digital eye strain?

Watch for:

• Headaches

• Eye rubbing

• Blurry vision

• Tired or watery eyes

• Trouble focusing

• Holding screens very close

If these symptoms are frequent, it’s a good idea to book an eye exam.
