I didn't purchase these from Amazon but a local dealer and just wanted to share my experience with these. First of all i LOVE the style and they look amazing BUTTTT, The nose pieces are a HUUUGGEEE flaw! They have left permanent marks on the bridge of my nose from wearing them on a road trip. It was horrible! I have taken them to my eye doctor and had them adjust them and to no avail, still leaves marks and now has put so much pressure on my nose i get headaches. The frame is too heavy and not distributed evenly so it all ends up on your nose and since the nose pieces never fit right and honestly i don't think are designed correctly to support all that weight. I would strongly recommend wearing these for a few hours and making sure this doesn't happen to you and return them if it does cause i have not found a way to fix the problem and now i'm stuck with them :-/  I called Oakley and they will not do anything about it! Said they have NEVER heard of this problem and don't know what to tell me. :-/ frustrating! Hope you all have better luck than me cause i would have loved for these to work.
