I won this auction ebay item# 250981737639 I am happy with the glasses for the price I paid. The nose joint feels fine to me. I'm sure it won't be much of a task to tighten up the ear stem with the right driver. Where it says there are pin prick size marks on the left lens it appears the lens has actually moved down out of the socket and these would be invisible if it was moved back up. The lens sits lower on the left lens and where the screw holds the lens in there are some tiny marks in the iridium where it has been tightened. The lens also does not sit quite right in the frame and needs to be moved back in which would hide any marks on the lens at all. I can almost see light at the top between the lens and frame and the little tail bit on the side of the lens appears to be holding it out. So my questions are. Should this be easy enough to do myself and if so what screwdriver do I need to fix it? Or if I took these to an Oakley store are they likely to be able to fix it up for me.
