Hi all, I am looking to buy a new pair of Juliets to replace my current pair that have seen better days. I believe both of these are legit real Juliets. They must be 4th or 5th gen. They have no serial number. How can I tell if the lenses are genuine Oakley lenses? I know the VR-28s had "Polarized" written on them. But not sure how to tell if the greys are legit. Also the second pair (next set of photos) are said to have the red iridium lenses. How can I tell if these ones are legit Oakley red iridiums too? Thanks so much all!
