Crowning the exclusive collection for women, The Oakley Dart Sunglasses are highlighted by the smooth contour of a single continuous lens. The crystal clarity of its wide peripheral view is possible only with HIGH DEFINITION OPTICS(R) (HDO(R)). For all-day comfort, the frame takes advantage of lightweight C-5&trade alloy. Extended lens coverage helps protect eyes from the sun's damaging light, and not a single ray of UV makes it through the optically pure PLUTONITE(R) lens material. The frame can also be customized with optional gradient lens shading.
