Sea Striker Bill Collector Polarized Sunglasses with Black Frame and Blue Mirror Lens protect your eyes from more than just the harmful UV rays of the sun. These 1.0mm polarized triacetate (TAC) lenses allow you to see the things you want - in the water, on the road - and eliminate what you don't, like blinding glare. And don't worry about distortion; these stylish sunglasses offer true color fidelity and superior clarity. Rubber nose pads and inlaid temple ends of these polarized sunglasses provide a comfortable wraparound fit that won't slip. The temple stops keep the folded temples from scratching the inside of your lenses when your glasses are stored.
