Oakley 31Thirteen Prescription Glasses in Detail . . .

31Thirteen™ goes beyond the less-is-more idea, blending the benefits of rimless architecture with the pure approach of signature Oakley style. Matched with the comfort of Unobtainium® earsocks, lightweight C-5™ alloy is honed into slender dimensions and shaped with smooth contours that give personality the respect it deserves.

Don’t confuse –less is more– with a minimalist approach. Oakley have put a great deal of science and art into this frame. The alloy combines five superheated metal compounds to achieve premium durability with extremely low weight. UNOBTAINIUM earsocks are specially formulated to increase grip with perspiration, so you will have a secure fit with all-day comfort. And with rimless architecture, there will be nothing to obstruct your view.

Frame Composition

Engineering breakthroughs in structural materials allow Oakley to produce lightweight, high performance frames that maintain superior protection and comfort. To produce the ultra-strong, ultra-lightweight chassis of Oakley wire glasses, five metallic compounds are fused into a cingle C-5 alloy. This frame material maintains resistance to ultraviolet radiation, humidity, thermal shock and chemical exposure.
