Oakley started with the bold shape of the Sliver, and rounded out the edges to create the smoother, sleeker Sliver R Sunglasses. Lightweight and durable Plutonite lenses block out 100% of harmful UV light while offering distortion-free optics. The incredibly light O-Matter frame is subtly flexible for enhanced comfort, and Oakley's patented Three-Point fit eliminates painful pressure points while holding the lenses in precise optical alignment.[lens/bridge/temple] 57 / 17 / 140mm.
