Digging through a junk drawer came across these in a bag. I've only had one pair of XMetals before my recent purchases. It was a pair of Juliet's in what I'd call rough plasma. I bought a set of VisionLenses in fire to preserve the OEMs, problem is I can't remember what the original lenses were. How can I tell if these Emeralds are Oakley's? Don't know serial #.
