I can verify both Juliet and XX have different sizes from old to new. The XX are especially drastic in difference with a 1mm difference in orbital size noted between a non-serial frame vs a low-digit Gen1. In fact, I can confirm 100% certainty that Oakley actually cut a new lens pattern for the newer XX after they created the new casting molds. If any of you have a really old frame and a really new frame, try taking the lenses out of both and do a comparison for yourself. Juliet are the same way but less drastic. The older frames run smaller, the newer frames run larger. I cut my lenses to best fit all the frames.
