Need your glasses for that momentary "QUICK GLANCE"? (i.e., to check a price while in the store, to look at a schedule or menu, etc) No need to dig through pockets or the purse. HANGAROUNZ are always within EASY REACH.
For the "QUICK GLANCE", simply SHORTEN the cords so that , when needed, the lens can be placed on the bridge of the nose and will be held there by the cords which are positioned under the ears and around the neck. When finished, remove the lens and allow it to fall back at rest FLAT against the upper chest.
