So I recently got a pair of the 649s of the classified section. I got the smallest size, 49mm, as I have a very small head. I was hoping for a quick critique of the fit. Whether they are too small or too big for me. Having a small head I am very self-conscious of extra large eye-wear and tend to shy away from anything that could make my head look even smaller. Please forgive the crappy cell phone pic. Thanks in advance.
