For anyone requiring reading glasses intermittently, these specs are heaven sent! The frame breaks in the front and clicks together once resting on your nose by way of two magnets. When not in use, they stay out of the way -- the glasses have a hard frame 'loop' that slips around your neck. As soon as you need them, you reach down and pull them up into place. I've tried lanyards -- they get caught on your seat belt strap and tangeled around your collar. I've tried my pocket -- they fall out. Nothing seemed to work, so I ended up buying eight or ten pair of cheap glasses and leaving them all over: habitat, car, at work, etc. CliCs are a wonderful way to avoid all that clutter.
