The Oakley Polarized Two Face XL Prizm Sunglasses is a great pair of shades for being on the water, driving around the city, or any other situation where glare reduces your ability to see beyond refracting light. Made with Oakley's durable O-Matter construction techniques, the Twoface is burly enough to withstand regular workout, whitewater jostlings, ski runs down the mountain, or any other action-sport context where durability will serve a premium. Plutonite lenses block 100% of harmful UVA, UVB, and UVC solar rays, so you can spend all day in the sun without harming your eyes. Plus, the polarized lenses cut 99% of blinding glare, so you can make out river features, see oncoming traffic and see past the surface while trying to land a lunker.
