Enjoy excellent protection and optimum optics with Uvex's Crow Pro shades. Uvex's eyewear blocks the whole spectrum of UV rays. In fact, that's where their name comes from: Uvex: uv x ex = ultraviolet excluded. These stylish, sporty specs also feature their scratchproof and fog-free Supravision nano technology, an open-frame design and three different sets of large, vented lenses, delivering clear vision in any lighting. And the soft nose pads and adjustable temples provide a comfy feel and a custom, no-slip fit.
