I need to buy some new sunglasses. I always had sunglasses common black and gray lens, but this time I am thinking about buying frogskins colored with iridium mirrored lenses. But do these glasses are versatile as the black ones? You can use any type of clothing or any time, without attracting much attention? In my local shop has these two models Crystal black / positive red Polished clear, violet What advise me? I want to use the glasses throughout the year, and not only in the summer, advise me to buy one of these two pairs? Tanks.
