I had a problem with the glasses, as did my sister. While they certainly do fit over regular glasses, they weren't snug and felt stretched out once they were put over our regular frames. I had to hold them in place. The attraction instructs you to keep both hands on the handles while in motion, but I had to bring one hand up to avoid them slipping off once my banshee started moving. Maybe size & shape of regular glasses come into play, as well as how stretched the attraction glasses you're handed may already be, since apparently some others had no problem.
