Oakley Cybr Zero is a lightweight, frameless sports sunglass with an open lens architecture and a low-bridge-oriented fit. The Polished Navy model uses Prizm Low Light lenses for conditions where preserving available light is important.
Its minimal construction is aimed at keeping the weight and visual bulk down while retaining a technical Oakley fit. The Prizm Low Light lens is especially suited to overcast, shaded or changing-light outdoor conditions.
