If you live an active lifestyle, sport sunglasses are the way to go. Goodr makes lightweight frames with impact-resistant lenses that don't bounce or slip when you run, hit the golf course, or stand in the student section all afternoon. Most of these pairs are polarized to cut glare in bright sun, and they're cheap enough that you won't stress if one goes missing at the lake. Suncloud, made by Smith Optics, and Blenders fill out the group with the same easy fit and more color to choose from.
