The Oakley Polarized Women's Break Up Sunglasses use a top shelf polarized Plutonite lens to cut glare from reflective surfaces, helping you see clearly around shimmering water and blinding snow. These shades feature a lightweight, stress resistant O Matter frame for hours of comfortable wear. Unobtanium nose and temple pads secure these sunglasses through long hikes and casual bike rides, and the sunglasses' toric lens geometry provides optimal peripheral vision, removing blind spots. Blocking the sun's harmful radiation, the polarized Plutonite lens filters out 100% of UV rays and high energy blue light that causes eye strain. This lens has an optional Iridium coating on ArcticVR28 Black Irid Polar only, balancing light transmission for crystal clear vision.
