As children grow up, they often get to experience some pretty amazing things. There's so much in this world to discover—and see.

Unfortunately, thousands of children in the U.S. endure eye injuries every year that can seriously threaten their vision. Many of these injuries are avoidable.

To help keep your kids' eyes safe, follow these tips from the American Academy of Ophthalmology and other experts:

Insist on proper eye protection. Many eye injuries occur during sports. For that reason, eye doctors recommend that kids wear eye protectors for numerous activities—including some you might not think about. This includes baseball, basketball, racquet sports, soccer, football and hockey.

When purchasing sports eyewear, look for polycarbonate lenses, which are stronger than regular lenses.

Keep risky products out of little hands. Make sure any harmful chemicals (including those that could accidentally be sprayed into the eyes) are stored safely out of reach of children.

Provide safer playthings. Avoid giving kids toys that shoot projectiles, such as little missiles. And remember: BB guns and air rifles are not toys, so children shouldn't play with them.

If your teen wears contacts, the lenses should be removed before swimming. Bacteria in water (even in crystal-clear pools) can grow on the lenses, increasing the risk of serious eye infections that can sometimes damage vision.

Walk the talk. Make sure you use proper eye protection during activities that could injure your eyes. Think yard work or DIY home improvement projects.
