In a pair of eyeglasses of the type having a front lens holding member, and side members, which hook over the users ear, each side member being mounted on a hinge,
- means to adjust the length of a side member by turning the side member to adjust the pressure of the side member against the head of the user, comprising a threaded shaft mounted in the side member, the end of the shaft bearing against the front member, whereby rotation of the shaft lengthens the end which, in turn, bears against the frame in such a way that the side members are displaced toward the wearer's temples, thereby increasing pressure.
