Hi. A few years ago, a friend gave me a pair of Oakleys that he no longer wanted. I never really wore them, so now I am thinking about putting them on ebay or something. It turns out though, that I know nothing about them. I am pretty sure that they are X-Metal Juliets made after 2004 because they have no serial number on the left ear piece. I think that they are the X-Metal titanium frames with fire lenses. The rubber appears to be in good shape, the legs stay in place when held up and are not too loose, and there is a little play in the nosepiece, but not too much. The lenses are definitely scratched and pitted, but it does not seem to noticeable to me when worn. The frames have no discernible scratches. My questions finally - Are these authentic? I am 99% certain they are, because the guy who gave them to me wasn't the type to buy anything other than real from a licensed dealer. Am I correct in suggesting that these are in fairly good condition, save for the lenses, from what you can tell by the pictures? I appreciate any help. Thank you.
