If you want the best clarity and protection on the planet, nothing comes close to Oakley's High Definition Optics. Its patented technologies surpass all tests of the American National Standards Institute.
ALL Oakley lenses are tested to meet ANSI high velocity and high impact standards. However, please note that only the INDUSTRIAL M-FRAME, SI BALLISTIC M-FRAME 2.0 and SI M-FRAME are marked with ANSI Z87.1-2003. Thus, while all other Oakley styles surpass these standards, we cannot endorse them as industrial safety glasses as they are not marked.
