I can assure everyone there are no differences in the Flak Jacket lenses for Asian Fit vs. Regular Fit. I only noticed this today as i bought a pair of black Flak Jackets to swap the orbital section with my USC Trojans Flak Jackets that were scratched. While switching things around, i realized the lens sizes were different Here's a pic of the new +Red lenses i got (top) vs. my old SC Trojans XLJ lenses that i got a few years ago (bottom - note the Trojan logo). It's kinda hard to tell in the picture, but the newer lenses are about 1/8 in longer at the bottom and flare out a bit more at the outside edge. The tops are still the same and will fit all Flak frames. I also have an older Text frame with +Red and you can kinda see the differences in curvature at the bottoms between them: Interesting, no?
