Oakley M Frame Heater Sunglasses

The Oakley M Frame Sunglasses changed the way the world looks at sports by turning sunglasses from a generic accessory into vital equipment. The M Frame®'s lightweight design offers all-day comfort while meeting ANSI standards for impact protection. Interchangeable lenses let you adapt to any sport environment, and the Unobtainium® components increase grip with sweat, keeping the frame securely in place. Ordinary sport shields are made by bending flat sheets in a simple curve. M Frame® uses true Polaric Ellipsoid® geometry to contour the lens in three dimensions for the best possible protection against sun, wind and side impact. This requires XYZ Optics®, a technology that maintains razor-sharp clarity at all angles of vision. It’s just one of the patented innovations that give you the unbeatable performance of High Definition Optics® (HDO®). Each M Frame® style has removable, interchangeable lens options that allow you to adapt instantly to any light condition.
