Very happy to find a place to talk about Oakley eyewear. I've had a couple pairs for many years, and of the two, my Ti02's are my favorite. Serial # XT043889A. The other pair are full-metal straight jackets and I use them as backups. The Ti02's could probably use some tightening and new rubber all away around, but I'm waiting until I get my eyes checked for an updated prescription. The plan is to have the Ti02's lenses prescription filled at a local Authorized Oakley Rx place nearby. Right now, they are regular lenses but I want to use them more so I need them changed out. My only hope is they keep them looking like Black Iridium lenses.
