For high-performance, distortion-free sunglass lenses, Oakley is tough to beat. Oakley has become an industry leader with innovative design and revolutionary materials. From a sport-performance standpoint, the Jawbone is one of Oakley's most exciting designs yet. Switchlock technology in the Jawbone frame allows you to change lenses with no stress to the frame and hardly any contact with the lens. This means you can replace your current lenses with a Jawbone Replacement Kit for whichever tint is appropriate for the current lighting conditions.At the heart of Oakley lens technology is Plutonite, a polycarbonate material that not only blocks all harmful UV-A, UV-B, UV-C, and harmful blue light up to 400nm, but also meets ANSI Z87.1 standards for high velocity and high mass impact resistance. The Jawbone replacement lens kit also gets High Definition Optics for distortion free optical clarity. Oakley's hydrophobic coating prevents moisture buildup, resists smudges, and repels contaminants. Oakley Jawbone Replacement Lenses are available in Black/iridium/polarized for bright light, Clear for low light and night riding, Light Positive/iridium for flat light, and Clear/black/iridium/photochromic for varying light conditions.
