For excellent protection, Uvex's Blaze sunglasses block the full spectrum of UV rays. In fact, that's where the Uvex name comes from: uv-ex stands for "ultraviolet excluded." These stylish, sporty glasses also boast perfect optics. With the included set of extra lenses, you're covered for most lighting conditions, so you can always have your eyes on the action. Plus, the adjustable nose pads and temples provide a custom, no-slip fit.
