How to check of shades have uv protection?

The sun is pretty cool and all, but there are some not so good things you can say about the sun too. For example, the sun likes to give off UV rays. If you’re not wearing UV400 protection sunglasses, that’s a big, big problem.

“When shopping for shades, the most important thing to look for is the level of UV protection offered by the lens. The safest bet is to buy sunglasses that provide 100% UV protection, or UV 400 protection. That means that the glasses protect your eyes from both UVA and UVB radiation.”
