The Oakley Polarized Women's Feedback Sunglasses are a high-performance, women-specific version of classic teardrop shades from the '70s. These shades feature a polarized Plutonite lens, cutting glare coming off shiny surfaces for fine-tuned vision without distraction. For the first time ever, Oakley fuses its C-5 alloy frame with an acetate stem, creating wire-frame sunglasses that excel at casual sports. No-snag nose pads comfortable cling to your face without pulling your hair, and Unobtanium stem pads ensure a secure fit. Blocking the sun's harmful rays, the polarized Plutonite lens blocks 100% of UV rays and high-intensity blue light that causes eye strain. This lens has an optional Iridium coating (only on wisteria pearl model), balancing light for crystal-clear vision. In addition, an optional gradient tint (only on polished chrome or polished chocolate 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.
