Does Screen Time Cause Myopia?

Does screen time cause myopia?

Not directly — but it contributes. Screen time on its own doesn’t cause myopia, but it’s closely tied to risk factors that do.

Why is outdoor time important?

Outdoor light and distance viewing help regulate healthy eye growth. Kids who spend more time outdoors are less likely to develop myopia — especially before age 10.

Is reading as risky as screens?

Yes. It's the near work that matters, not the medium. Long stretches of reading or gaming without breaks both increase myopia risk.

What can parents do?

• Encourage 90+ minutes of outdoor play daily
• Take 5–10 minute distance breaks every 30 minutes of close-up work
• Use screens at eye level, with good posture and lighting
• Schedule annual eye exams to catch early changes
• Explore myopia control options if your child is already nearsighted
