Every parent knows that they need to limit their kid’s screen time. But in the age of virtual learning (thanks, pandemic), many kids have to stare at screens for hours.

Virtual learning is not great for your child’s eye health. But these tips from pediatric optometrist Alexandra Williamson, OD, can keep your child’s eyes healthy — even when their computer is their classroom.
What is digital eye strain?
Digital eye strain, also known as computer vision syndrome, isn’t a medical condition that only sick people get. It’s a term that describes visual problems that can happen when you use devices like computers, tablets or smartphones. The longer you use a device, the more likely you’ll experience digital eye strain. And if you use devices every day, eye problems can get worse over time.
Many people experience dry eyes after a long day at the computer or too much time scrolling on their phones. “When we use digital devices, we blink less, and we don’t even notice,” says Dr. Williamson. “The reduction in blinking affects kids, too. They lose their tear film, which can cause dry eyes, vision problems and discomfort.”
The eye muscles can get fatigued from too much screen time, too. “Our eye muscles have to work harder to see things up close, even when we’re young,” Williamson explains. “The eye muscles get tired out like any other muscle during heavy use.”
How screens can harm children’s eyes
Tablets, phones and other screens aren’t good for your eyes, no matter how old you are. But children may be especially prone to getting digital eye strain because of their age.
“Staring at a screen is not what human beings have evolved to do,” Dr. Williamson says. “A child’s vision develops rapidly up through about age 10. And even after that, their visual system is still growing and changing. The age when the visual system is considered to be fully mature is different for every child.”
Signs of digital eye strain in children
Children may not understand or be able to tell a parent that their eyes are bothering them. If your child is looking at a screen for long periods, watch for:
- Frequent eye rubbing.
- Avoidance of online classes or near work.
- Frequent blinking.
- Build-up or crust on eyelids or lashes.
- Complaining of blurry or double vision.
Use the 20-20-20 rule
Maybe you’ve noticed your child struggling with eye strain. Now what?
Help your child take frequent breaks from the screen with the 20-20-20 rule. “Every 20 minutes, look at something at least 20 feet away for 20 seconds,” Williamson explains. “This gives your eyes a break from looking at the close target.”
For even better results, combine the 20-20-20 rule with regular outdoor play. “Outside time is good for kids’ eyes,” says Dr. Williamson. “When kids spend more time outside and less time looking at close objects, they lower their chances of becoming nearsighted.”
Don’t use drops
The pharmacy shelves are stocked with all kinds of eye drops and artificial tears. But don’t use any of these on your child without asking a health professional first.
Any parent who’s tried to give eye drops to a squirming, screaming child may welcome this advice.
“I don’t recommend drops for children unless their eye doctor says to use them,” says Dr. Williamson. “There are so many types, and some can be harmful if they’re not used correctly.”
Start visiting the eye doctor sooner than later
“The best thing you can do is get your kids to a pediatric eye doctor for an exam, even if they don’t have eye problems,” Dr. Williamson says. “The American Optometric Association recommends regular eye exams for children starting at age 6 months. By the time they are 5 years old, they should see their eye doctor at least once a year.”
Vision is an important part of overall well-being. Talk with your pediatrician or eye care provider about how you can keep your child’s eyes healthy.
