Dedicated to the woman with an active, water-based lifestyle, Costa Del Mar WaterWoman 580P Polarized Sunglasses for Ladies have a narrow-fitting large frame with beautifully angled temples and seamlessly integrated Hydrolite accents. These Costa sunglasses combine 100% UV protection with polarized lenses and modern styling to create a style that's never out of its depth. Polarized and outfitted with a mirror coating (on select styles) to fight glare, these Costa Del Mar women's sunglasses boast lightweight plastic lenses that are impact- and scratch-resistant. 580 technology goes beyond polarization to produce the best lenses on the planet by selectively filtering out harsh yellow and harmful blue light, making colors brighter and objects appear more defined. The frames are made from tough, durable, co-injected nylon using an eco-friendly bio-resin process (using castor oil instead of petroleum) to reduce emissions and Costa's overall carbon footprint. As elegant and strong as the ladies who wear them, Costa Del Mar WaterWoman sunglasses include a case, a cleaning cloth, and a mfrs. limited lifetime warranty.Manufacturer style #: WTW.
