I bought these for my dad for Father's Day. He has been using $10 gas station sunglasses for years and had no idea what he was missing. I got him the the Black/Gray. We went to the lake and he was suprised that he could ACTUALLY SEE! The only thing he said he didn't was that the lenses were so dark, I tried to tell him that it was by design but he didn't get it. GREAT GLASSES!
