Why Are My Eyes Watering? Common Causes and Treatments
July 22, 2026
From online learning and homework to video games and streaming services, screens have become a regular part of children’s daily lives. While technology offers many educational and entertainment benefits, too much screen time can affect your child’s eye comfort, vision, and overall well-being.
Many parents wonder how much screen time is actually too much. The answer depends on your child’s age, the type of activities they’re doing, and whether they’re taking regular breaks. Although screens do not permanently damage healthy eyes, excessive use can lead to digital eye strain, dry eyes, headaches, and may contribute to the progression of childhood myopia (nearsightedness).
Understanding healthy screen habits can help protect your child’s vision now and in the future.
How Much Screen Time Is Recommended?
There isn’t a single number that works for every child, but health experts generally recommend limiting recreational screen time while encouraging frequent breaks during educational activities.
Children who spend long periods on tablets, computers, smartphones, or gaming devices should avoid using screens continuously for hours without resting their eyes.
Instead of focusing only on total screen time, parents should also consider the quality of screen use, the viewing distance, room lighting, posture, and whether children spend enough time outdoors.
Outdoor play has been shown to support healthy visual development and may help reduce the risk of myopia in children.
What Is Digital Eye Strain?
Digital eye strain, sometimes called computer vision syndrome, occurs when the eyes become tired after extended screen use.
Children may not always recognize or communicate their symptoms, making it important for parents to watch for warning signs.
Common symptoms include:
Tired eyes
Headaches
Blurry vision
Dry or watery eyes
Frequent blinking
Rubbing the eyes
Difficulty concentrating
Neck or shoulder discomfort
These symptoms often improve after taking a break, but if they occur regularly, your child should have a comprehensive eye exam.
Can Too Much Screen Time Damage a Child’s Eyes?
Current research suggests that screens themselves do not permanently damage healthy eyes.
However, excessive screen use can increase eye strain and encourage children to spend less time outdoors. Studies have shown that children who spend more time outside may have a lower risk of developing or worsening myopia.
That’s why eye care professionals recommend balancing screen time with outdoor activities and healthy visual habits.
Tips to Protect Your Child’s Eyes
Parents can help reduce eye strain by encouraging a few simple habits.
Follow the 20-20-20 Rule whenever possible. Every 20 minutes, have your child look at something at least 20 feet away for 20 seconds.
Other helpful tips include:
Keep screens about an arm’s length away.
Adjust screen brightness to match the room.
Encourage children to blink regularly.
Use proper lighting to reduce glare.
Maintain good posture while using digital devices.
Schedule outdoor play every day.
Avoid screen use immediately before bedtime.
These small changes can make a significant difference in eye comfort.
When Should Your Child Have an Eye Exam?
Many vision problems aren’t obvious, especially in young children.
Your child may need an eye exam if you notice:
Sitting very close to screens
Squinting frequently
Complaining of headaches
Covering one eye
Difficulty reading
Poor school performance
Holding books very close to the face
Frequent eye rubbing
Even if your child doesn’t complain about their vision, regular comprehensive eye exams are important because children often assume everyone sees the way they do.
Early detection allows vision problems to be treated before they begin affecting learning and everyday activities.
How Parents Can Build Healthy Screen Habits
Creating healthy routines is often more effective than simply limiting screen time.
Encourage children to balance digital activities with reading printed books, outdoor games, sports, creative hobbies, and family activities.
Model healthy screen habits yourself by taking regular breaks and limiting unnecessary screen use during family time.
Good visual habits developed during childhood often continue into adulthood.
