Something is very wrong. The "clip/lock" tab in the frame is almost 1 mm too far away to click into the lense notch. The Vigilante glasses were originally bought here about 2 years ago have been good glasses and the original lenses have been out and back in several times without any problems. I'm assuming the OEM frames and glasses were "normal" and somehow these new lenses are built to a different spec or something went wrong in production. BTW, I am following the instructions on lense removal and installation. Also, after struggling for a half hour, I began a closer look at the frames and new lenses/old lenses and sure enough, the new lenses are slightly larger. Fixable but you should not have to modify a new lense.
Pros: Nice looking lens
Cons: won't clip into the Vigilante frame
