DetailsBeyond polarized.No sport is complete without a loyal pair of glasses, a pair you can depend on when the road gets rocky or the waves get sharp. A pair like Costa's Corbina Mossy Oak Camo Polarized Sunglasses balances the modern style of sport sunglasses with the aggressive you'd expect from hardcore fishermen. Skill craftsmen assemble each pair, combining a rugged nylon frame, stainless steel integral hinges, and Costa's custom lenses. Its large size protects your eyes from flying lures, rocks, or bugs while its width offer an unprecedented panoramic angle of view. No-slip Hydrolite rubber holds fast to your nose and temples to prevent this pair from being a "man overboard!" The Costa 580 Polycarbonate lens reaches far beyond the bounds of mere polarization. By blocking yellow light at exactly 580 nanometers, the lens relieves eye strain while enhancing color, improving your overall comfort. Crystal clarity is achieved by the hindrance of shortwave, high-energy blue light, cutting haze and blur like you've never seen in sunglasses. Because a long day outside usually means a hefty helping of sun exposure, Costa ensured the 580 technology to be 100% UV-blocking and polarized, virtually eliminating reflected glare of any kind.Proposition 65 Warning for California Consumers: This product contains chemicals known to the State of California to cause cancer and/or birth defects or other reproductive harm.Costa polycarbonate 580 lensPolarized100% UV protectionLarge face sizeNylon frameStainless steel integral hingeHydrolite rubber padsHard case includedPlease see size chart for information on lens optionsItem #CDM000FTech SpecsLensCosta 580 polycarbonatePolarizedyesFramenylonHingestainless steel pinCase IncludedyesFace SizelargeBase Curve8Recommended Usebiking, fishing, cyclingManufacturer Warrantylifetime
