Oakley Ten is the classic Oakley look, amped with volume and rigged with tech. Youll have sculpturally integrated hinges with dual cam action, a comfortable Three-Point Fit, and the optical performance you need for a life with momentum. It uses XYZ Optics (a benefit of High Definition Optics (HDO)) to keep your vision razor sharp at every angle of view, even with 8.75 base lens curvature. Thats what the Ten offers, and it means youll have a wide peripheral view with extra coverage to block annoying things like side glare, wind, and the type of impact that can ruin your outlook. Even with all that curvature, youll have optical precision that meets ANSI Z87.1 standards, and same goes for impact protection because the comfortably lightweight O-Matter frame is beyond durable.
