Is Too Much Screen Time Harming Children’s Vision?

As children spend more time tethered to screens, there is increasing concern about potential harm to their visual development. Ophthalmologists are seeing a marked increase in children with dry eye and eye strain from too much screen time. But does digital eye strain cause lasting damage? Should your child use reading glasses or computer glasses?
As you send your kids back to school this month for more time with screens and books, Chippewa Valley Eye Clinic along with the American Academy of Ophthalmology (AAO) are arming parents with the facts, so they can make informed choices about their children’s eye health.

It’s a fact that there is a world-wide epidemic of myopia, also known as nearsightedness. Since 1971, the incidence of nearsightedness in the US nearly doubled, to 42 percent. In Asia, up to 90 percent of teenagers and adults are nearsighted. Clearly, something is going on. But scientists can’t agree on exactly what.

“Since 1971, nearsightedness in the US nearly doubled to 42 percent.”

A new study appearing in the journal of the AAO, offers further evidence that at least part of the worldwide increase in nearsightedness has to do with near-work activities; not just screens but also traditional books. And, that spending time outdoors — especially in early childhood — can slow the progression of nearsightedness. It remains unclear whether the rise in nearsightedness is due to focusing on phones all the time, or to light interacting with our circadian rhythms to influence eye growth, or none of the above.

While scientists look for a definitive answer, there is no doubt that most computer users experience digital eye strain. Kids are no different from adults when it comes to digital eye strain. In fact, they can experience dry eye, headaches and blurry vision too. While symptoms are typically temporary, they may be frequent and persistent.

But this does not mean they need a prescription for computer glasses or that they have developed an eye condition of middle-age that requires reading glasses, as some suggest. It also doesn’t mean blue light coming from computer screens is damaging their eyes. It means they need to take more frequent breaks. This is because we don’t blink as often while using computers and other digital devices. Extended reading, writing or other intensive near-work can also cause eye strain. Ophthalmologists recommend taking a 20 second break from near-work every 20 minutes.

“Children need to take more frequent breaks. This is because we don’t blink as often while using computers and other digital devices.”
 

Here are ten tips to help protect your child’s eyes from computer eye strain:

 

  • Set a kitchen timer or smart device timer to remind them.

  • Alternate reading an e-book with a real book and encourage kids to look up and out the window every two chapters.

  • After completing a level in a video game, look out the window for 20 seconds.

  • Pre-mark books with a paperclip every few chapters to remind your child to look up. On an e-book, use the “bookmark” function for the same effect.

  • Avoid using a computer outside or in brightly lit areas, as the glare on the screen can create strain.

  • Adjust the brightness and contrast of your computer screen so that it feels comfortable to you.

  • Use good posture when using a computer and when reading.

  • Encourage your child to hold digital media farther away, 18 to 24 inches is ideal.

  • Create a distraction that causes your child to look up every now and then.

  • Remind them to blink when watching a screen.
