Screen Time Is the New Normal, But What Does It Mean for Eye Health?
Let’s face it; screens are everywhere. Whether it’s online learning, video games, or streaming their favourite shows, kids are using screens more than ever before. And while technology offers amazing benefits, it can also place a lot of strain on developing eyes.
Studies have shown a clear link between prolonged screen use and vision issues in children, including:
- Eye strain and fatigue
- Blurred or fluctuating vision
- Dry or irritated eyes
- Difficulty focusing at a distance
- Increased risk of myopia (nearsightedness)
At Market Mall Optometry in NW Calgary, we work with families to manage the effects of digital device use on children’s eyes, through early detection, education, and personalized vision care.
The Impact of Screen Time on Kids' Vision—And What You Can Do
1. Digital Eye Strain in Children Is Real
Kids may not always have the language to describe what they're feeling, but symptoms of digital eye strain can include:
- Rubbing their eyes frequently
- Squinting at the screen
- Avoiding near work or reading
- Complaining of headaches or tired eyes
- Trouble sleeping after evening screen use
The closer and longer a child focuses on a screen, especially phones and tablets, the more effort their eyes need to maintain focus.
What to do:
- Encourage the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds
- Ensure screens are at eye level and not too close to the face
- Keep screens out of dark rooms to reduce glare and blue light impact
2. More Screen Time = Higher Myopia Risk
The global rise in myopia among children is directly linked to increased near work and reduced time outdoors. Screen-heavy habits can accelerate myopia development, which may lead to serious long-term eye health issues later in life.
What to do:
- Book regular children’s eye exams to catch changes early
- Encourage at least 90 minutes of outdoor play daily, which helps slow myopia progression
- Ask us about myopia control strategies, including specialized glasses or contact lenses
3. Screens Before Bed Disrupt Sleep and Eye Recovery
The blue light emitted by screens can interfere with melatonin production and disrupt sleep cycles. This is especially concerning for kids, whose eyes are still developing and more sensitive to light.
What to do:
- Shut down screens at least 1 hour before bedtime
- Use blue light filters or night mode in the evening
- Create a calming, screen-free bedtime routine to support healthy rest and eye recovery
4. Children Often Don’t Complain—They Just Adapt
Many kids don’t realize they’re straining their eyes. Instead, they adapt by holding screens closer, leaning in, or avoiding certain tasks. That’s why early eye exams are so important, even before your child starts showing signs.
At Market Mall Optometry, we offer age-appropriate, stress-free exams designed to detect vision problems before they interfere with learning or development.
