With deceptively casual looks, the Native Eyewear Women's Polarized Perazzo Sunglases pack in high tech eye protection and glare elimination, while offering a comfortable, non slip fit. They also prove that high tech features are perfectly at home in a sassy, fashionable little package. The Perazzo's advanced N3 polarized lenses selectively block out specific parts of the light spectrum and eliminate glare to provide a crystal clear view with increased contrasts and optimal depth perception, while offering top notch protection against both infrared and UV rays. The Rhyno Tuff Air frame, made of a high performance thermoplastic, is super lightweight and as rugged as its name implies: it's made to withstand high velocity collisions and temperature extremes. So you won't have to panic if you accidentally drop the sunglasses on the ground, or if you're out exploring in a blazing hot desert or high elevation camping in sub zero temperatures. The Perazzo's frame is shaped to provide comfortable and stay put grip, while special, non slip nose pads ensure the sunglasses stay securely in place. The stylishly feminine frame is fashionable enough to wear around town on any day, but functional enough for wearing during active outdoor pursuits. Native Eyewear includes a semi rigid case and a soft pouch along with the sunglasses so you can keep them in good shape once they're off your face.
