These glasses have a magnetic closure on the bridge and continuous temples that form a wrap-around neck band. Place the flexible neckband around your head and the magnetic closure in the bridge . The temple length will adjust an inch or so. Relax,  magnetic readers won't slide down your nose or slip off if you happen to bend over a bit too far. When you want to take them off, simply separate the eye pieces and let them hang around your neck.
