Oakley FrogskinsPolished Black / Grey LensesPresenting legendary Oakley Frogskins. When it first appeared in the 80s, it was the first Oakley sunglass to feature two lenses. And its iconic look hasn't changed since. Its classic keyhole bridge and Wayfarer-esque shape still turns heads too. And retro Oakley motifs line each temple (a unique sign of authenticity).Pure Plutonite lenses give the clearest views. High Definition Optics stop light bending to prevent distortion (meaning every object shows up in its real place).Frogskins sunglasses are crafted from versatile O-Matter. That means they're lightweight for the greatest comfort yet incredibly strong. Three-Point Fit holds them snugly in place without irritating pressure points.All lenses block 100 per cent of UVA/UVB/UVC rays and blue light up to 400 nm. Oakley sunglasses come with a two year warranty.
