Protecting your eyes from the sun’s harmful UVA and UVB rays is important. It’s also important to choose the right sport sunglasses to protect your eyes while you run. You need glasses that won’t fall off, or get uncomfortable, no matter what conditions you’re running in. Also consider anti-glare lenses, traction straps, and anti-fog glasses. Many running glasses come with interchangeable lenses so you can be prepared for whatever comes into view.
