Engineering breakthroughs in structural materials allow Oakley to produce lightweight, high-performance eyewear frames that maintain superior protection and comfort. The polymers in O Matter frames are formulated for high durability, as well as controlled flexibility for improved safety during impact. To produce the ultra-strong, ultra-lightweight chassis of Oakley Wire frames, five metallic compounds are fused into a single C-5 alloy. Both frame materials maintain resistance to ultraviolet radiation, humidity, thermal shock and chemical exposure.
