So, when these first came out a while ago these came with etching on the 24k lens. I saw a pair today and they didn't have the etching, so I thought these were a unique manufacturing mistake. Turns out they weren't and all they pairs they had didn't have etching. Not only that, but the official Oakley photo of them now doesn't show the etching. Have Oakley quietly changed the design? Can't they afford etching anymore?
