I hardly ever fall asleep with them on. If I'm in bed, never, but if I'm on the couch watching a movie, or if I'm drinking and I pass out, then yeah. My frames are flexon, so they won't break for sh-t, but I need new ones, and I don't want to spend the money on flexons anymore. I can see fine without them. I'm not wearing them now, as a matter of fact...haven't worn them for 2 days.
