In today’s digital age, children are spending more time in front of screens than ever before—whether it's for online learning, video games, or entertainment. As an optometrist, one of the most common concerns parents bring up is: "Is screen time bad for my child’s eyes?" The short answer is yes, excessive screen exposure can lead to several eye-related issues.
Understanding Digital Eye Strain in Children
Prolonged use of digital devices—tablets, smartphones, computers—can lead to digital eye strain (also known as computer vision syndrome). Children may not always recognize or express that they are uncomfortable, making it harder for parents to detect.
Common symptoms include:
Blurry vision
Headaches
Dry eyes
Eye fatigue
Difficulty focusing
If left unchecked, these symptoms can affect a child’s concentration and academic performance.
Link Between Screen Time and Myopia Progression
Recent studies have shown a strong correlation between increased screen time and the rise in myopia (nearsightedness) among children. Near work activities, including reading and using digital devices for prolonged periods, can accelerate the development of myopia. As an eye care provider, we are seeing more children being diagnosed with myopia at a younger age—and progressing faster than ever before.
Importance of the 20-20-20 Rule
One effective strategy I often recommend to parents is the 20-20-20 rule. Encourage your child to:
Take a break every 20 minutes
Look at something 20 feet away
For at least 20 seconds
This simple rule helps relax the eye muscles and reduce fatigue, promoting better long-term visual health.
Encourage Outdoor Activities
Research shows that children who spend more time outdoors are at lower risk of developing myopia. Natural light exposure and distance viewing help regulate healthy eye growth. Aim for at least 1–2 hours of outdoor play daily to balance screen exposure.
Tips for Managing Screen Time
Here are some optometrist-approved tips to help protect your child’s eyes:
Set screen time limits for non-educational use.
Adjust screen brightness to match ambient lighting.
Ensure proper posture and distance (screen should be at least 18–24 inches from the eyes).
Schedule regular comprehensive eye exams—even if your child isn’t complaining of any vision problems.
When to See an Optometrist
If your child frequently complains of headaches, rubs their eyes often, squints, or seems to avoid screen use entirely, it could be a sign of visual discomfort or an underlying eye issue. Early detection and treatment are key in managing eye strain and preventing myopia progression.
Conclusion: As screen time continues to be a part of children’s daily routines, it’s essential to prioritize children’s eye health. By setting healthy boundaries, encouraging outdoor time, and scheduling regular eye exams, you can help protect your child’s vision in the digital world.
