I know I'm late in this discussion but Aviators all the way! I got some SWEEET gold reflecting BCBG's. They cost my a fortune and I need to get the lenses replaced... Plus the golden color on the frame is sort of rusting :(
They make me look like a criminal or someone involved in porn.
I think I'll stick to transition lenses a little longer, since I treat my sunglasses too poorly (always shoving them unprotected into pockets, bags etc, sitting on them)
