Clip-on earrings have been worn by women since the Victorian era, when they had simple screw-on backings. Modern clip-on earrings consist of a paddle-shaped clasp or clip. Sometimes the backs of the clips can become bent or are made too tight at the factory. Clip-on earrings that are too tight can pinch your ears and be very uncomfortable. If you find that your clip-on earrings are too tight, you can loosen them yourself with a few simple tools.
Shut the clasp of the earring.
Insert the clip-on earring key or the blade of a small flat-blade screw driver underneath the center lever tongue, which will be sticking out of the bottom past the hinge of the clasp. Pry up the tongue with the earring key or screwdriver to lift it up slightly from its current position and loosen it.
Open and close the clasp and try the earring on to see if it is loosened. If it has not, pry it up a little more and try it again. Continue moving the tongue up until the earring sits comfortably on your ear.
