Let the look that helped launch Oakley shield your eyes from harmful UVA/UVB/UVC rays with the Half Jacket 2.0 Sunglasses, featuring pearl frames and violet iridium lenses. The violet lenses feature a neutral tint with an iridium coating, to tune contrast and reduce glare, and are well-suited for medium to bright light. The XYZ Optics extend visual clarity, lens curvature opens your peripheral view, and High Definition Optics meet or exceed the testing requirements of the American National Standards Institute for optical clarity, visual fidelity, and impact resistance. The O-Matter frame material is stress-resistant, durable, and lightweight for all-day comfort and protection, and the Unobtanium earsocks provide a non-slip grip. You can purchase optional interchangeable lenses for adapting these glasses to changing light conditions.
