Are the Square Wire 2.0 lenses all the same or are they different if you have the Spring Hinge version? Thanks all!

Hi all! I purchased my first pair of Oakleys in '97, one of the early M. Still use them, broken frame and all, for long driving trips. I now have a second M for sports (cycling, running, baseball/softball) and a pair of Square Wire 2.0 SH.
