The Oakley Women's Feedback Sunglasses are a modern, women specific version of timeless teardrop shades from the '70s. For the first time ever, Oakely fuses its C 5 alloy frame with an acetate stem, creating wire frame sunglasses that transition seamlessly from the coffee shop to your favorite hike. No snag nose pads comfortably cling to your face without pulling your hair, and Unobtanium stem pads ensure a secure fit. Shielding your eyes from the sun's harmful rays, the Plutonite lens blocks 100% of UV rays and high energy blue light that causes eye strain. This lens has an optional Iridium coating on Metallic Black, and Polished Gold models, balancing light transmission for crystal clear vision. In addition, an optional gradient tint on Grapefruit Pearl, Rose Gold, and Honeydew Pearl models provides varied light transmission, gradually becoming darker as you look downward. Gradient shading is especially useful when you're driving, cutting glare from the bright sky without blocking the view of your car's gauges or dashboard.
