Why are they called sleeper earrings?

Sleeper earrings are called by their name due to the fact that some people sleep in them. Generally, sleeper earrings range from 8 to 20 millimeters in diameter. Because they are small in size, they are less likely to get caught on pajamas, hair, pillows and bedding. However, they don't completely eliminate the risk. As a result, most experts recommend removing all earrings, including sleepers, prior to bed. Find a wide range of hoop earrings on 1stDibs.
