Costa Women's Isabela 580P Polarized Sunglasses Tortoise/silver Mirror. If you're passionate about your waterlife. If a little danger just spices things up.These. Are. Your. Sunglasses.Named after Isabela Island, the largest of the Galápagos Archipelago and one of the most volcanically active places in the world, Costa's Isabela Sunglasses offer an intriguing (and dare we say thrilling) design that separates you from the mass of male-dominated frame styles. They may take a nod from fashion, but these are highly durable sunglasses with large-fit TR-90 nylon frames that are made with resin from the castor plant. This bio-based resin offers a 70% reduction in emissions over petroleum-based resin, helping to reduce the overall carbon footprint. Reflective glare and eye strain is minimized or eliminated altogether with their 100% polarized, scratch-resistant 580P polycarbonate lenses. Hydrolite nose and temple pads will keep them securely on your face. Although, if you want to be extra sure they don't end up in the drink, a neoprene retainer or leash (sold separately) is inexpensive insurance.580P Polycarbonate LensesPolarized to eliminate reflective glare and reduce eye strainLightweight, yet durableImpact resistantC-Wall scratch-resistant, smudge-free barrier100% protection from UV lightAbsorbs harmful high-energy blue light (HEV)Cuts haze and blur for greater clarityFilters out harsh yellow lightEnhances reds, greens and bluesSharp contrast with high definitionTR-90 Nylon FramesCastor oil is used to make the bio-based plastic resinBio-based resin offers a 70% reduction in emissions over petroleum-based resinReduced overall carbon footprintFlexible, yet tough and durableLightweightHold their shape under harsh conditionsResistant to heat and coldHydrolite hypoallergenic rubber nose and temple pads prevent slippingCorrosion-resistant, stainless steel optical spring hinges keep their shapeKey FeaturesWomen's large fit580P polycarbonate polarized lensesHeavy-duty TR-90 nylon framesIncludes hard case and cleaning clothPrescription readyLimited lifetime warranty
