The glasses kept sliding down my nose so I tried to adjust the ear pieces. The glasses have metal frames with a plastic cover over the ear pieces. As I tried to bend the ear piece to fit my ear, it snapped off! The metal frame does not extend all the way to the end. So, I can't use the glasses, they don't fit properly and I don’t feel right about returning a broken item, so I'll just buy reading glasses somewhere else. If you buy these glasses and find they don't fit right, good luck trying to adjust them!
