Great lenses, authentic Oakley brand! It took a little practice to get them seated in my frames, but that was a user issue, not the lenses' fault of design. These replaced my original 10 yr old VR28 lenses, and I really enjoy the polarized effect of these!  I know they're designed for shallow/freshwater activities, but I wear them while running or driving, in weather conditions ranging from sunny to overcast, and find they keep eye fatigue to a minimum.
