The Oakley Square Wire Polarized Sunglasses has a fresh look of casual sophistication that still brings the best of comfortably lightweight C-5™ alloy. The nose pads are adjustable for a made-for-you feel, and Unobtainium® earsocks increase grip with perspiration to maintain a secure Three-Point Fit. The Square Wire offers the wide peripheral view of 8.75 base lens curvature with High Definition Optics®, including XYZ Optics® to extend clarity all the way to the lens edge. Five metal compounds are combined in a blast furnace to produce durable C-5 alloy. When you feel the comfort of its low weight, you’ll appreciate the effort. As far as performance and protection, Square Wire meets all ANSI Z80.3 standards for optical clarity and impact resistance.
