A lot of time and effort went into the Women's Tie Breaker Sunglasses to combine a timeless look with the most innovative optics that Oakley has to offer. Fine-tuned for daily commutes, Oakley's Prizm technology enhances contrasts, makes colors more vivid, and highlights details in urban environments. Prizm also comes HD Polarized for lifelong glare-elimination. The Sunglasses' Plutonite lenses filter out 100% UVA, UVB, and UVC rays, as well as blue rays up to 400nm. They also meet Oakley's High Definition Optics, which exceed the American National Standards' ratings for optical clarity, visual fidelity, and impact-resistance. Oakley made the frame out of sleek-yet-strong C-5 alloy with soft acetate temples for a harmonious blend of style and comfort.
