Child reading glasses
Child reading glasses are the children's version of reading glasses. When worn by adults, they are much larger and will hover in front of the wearer's forehead.

They can be reverse-pickpocketed from at least one of the nameless children in Little Lamplight. Using a full-body or full-head piece of apparel (such as a radiation suit or power helmet) will make the non-player character remove all headgear, enabling you to pickpocket it.

Reading glasses
Reading glasses are classic fabricated glasses for those who suffer from presobyopia, a condition that comes with age and makes focusing on near objects, specifically text, more difficult. From the Ancient Greek, meaning "old eyes" or "elder eyes".
