A friend of mine is selling me his aluminum C-Six but they have a miniscule scratch on one of the lenses and I wanted to get them replaced since everything is in flawless condition aside from the scratch. I called Oakley and they said they could sell me some lenses but I need to send the sunglasses in so they could replace them professionally, which is fine. I just want to know what the exact process is in replacing the lenses and if I could do it myself without ruining them. I was thinking about wearing them on special occasions, but if I did I would want to use the lenses with the scratch on them. Had anyone ever tried swapping the lenses out? Could anyone do a video or describe to me what to do? Thanks.
