With the amount of time children will be spending indoors and in front of a screen as the new school year begins, parents should be paying attention to their children’s eye health.

On the rise since the 1970s, myopia or nearsightedness, is a vision condition in which people can see close objects clearly, but objects farther away appear blurred. People with myopia can have difficulty clearly seeing a movie or TV screen, a whiteboard in school or while driving, according to optometrists.

One way parents can help stop the onset of myopia is getting their children outside as often as they can. Experts have found that kids who spend more outdoor time tend to have less likelihood of developing myopia, and getting outside regularly has many benefits for children’s eye health.

Here are some signs that children could be developing eye issues, according to Tree House Eyes:

- Eye rubbing

- Squinting

- Avoidance of reading

- Head tilting

- Watery eyes

- Eye strain

- Headaches

Experts recommend children take a break from digital devices, at least briefly, every 20 minutes, and screens and reading materials should be 16 to 20 inches away from the eyes.
