Oakley Oil Drum Sunglasses: When the premier edition of the Oakley Oil Drum Sunglasses hit the streets, people got out of the way. That kind of thing tends to happen when a perfect storm of science and art makes style so aggressively original that it calls down its own thunder. Durable yet lightweight O Matter® frame material is shaped with a unique geometry that offers a comfortable fit on medium to large faces. Oakley engineered it with sculpturally integrated hinges that work with dual cam action, and shaped the contours to create 8.75 base lens curvature. That’s how it offers such a wide peripheral view, and thanks to High Definition Optics® (HDO®) and XYZ Optics®, you get razor-sharp clarity at every angle of vision.
