Okay, I have talked to a couple CSRs at Oakley. several have said the current M-frame lens will not work in the older frames. My older M Frame lenses are loose in my RX M Frame and the RX lens will not even fit in the older frame.. Anyway, I want to get a Clear lens for a pair of M frames to use at work as safety glasses (up until I had contacts my RX glasses were fine) So here is my OLDER M Frame: Here are my Newer RX M Frames. I had gotten a new complete RX Frame 7/7/2006 so I am wondering if the current Lens will fit They look current but how else can I tell?
