Oakley made the unique Minute 2.0 Sunglasses for active people with smaller faces.These Oakley shades have Transition lens technology that responds to whatever lighting condition you are in. When you step into the shade, the lenses lighten up. Head out in bright sun and they will darken to block 100 of UV rays. The shatter-resistant Plutonite lenses have a Hydrophobic coating which repels rain, sweat, skin oils, and dust to keep the lenses clear. The lightweight frames have Oakleys Three-Point-Fit technology so you wont have to worry about your shades sliding off.
