The Oakley Frogskins (Low Bridge Fit) OX8137A echoes a timeless, retro square silhouette but tailored for lower-nose-bridge wearers. Its frame is made of O-Matter™, which keeps it light yet sturdy and comfortable for all-day use. The design is full-rim, and it’s optimized for Oakley Authentic Prescription lenses, with internal features to support optical clarity and lens retention.
