The sunglass model Oakley Heliostat (OO9231) reinvents a high-wrap silhouette with modern lines and advanced tech. The O-Matter™ lightweight but durable frame has a three-point fit system with internal Unobtainium® earsocks and molded nosepads that stabilize the fit during hard activity. The wraparound lenses, in Prizm™ or polarized options, further enhance contrast and clarity while protecting eyesight from glaring sunlight.
