CliCs are comprised of a solid headband that goes around the back of the head and connects to the front eyepieces that attach with  powerful earth magnets on the bridge of the nose. These glasses are one solid piece, they do not fold up. They were created to be worn all day hanging around your neck so that they are always available when you need to read something! No more fishing around for your glasses or perching them on your head where they fall off as soon as you bend over. They are lightweight and convenient, making wearing reading glasses ever so much more pleasant and easy. Put them on in the morning, and at night, hang them on a doorknob or simply put them down on a table. They never sit on the lenses, so no scratching will occur.
