Abstract
A pair of spectacles having a curved lens body having opposite ends, and a pair of curved left and right arms connected to the opposite ends of the body. A hinge connection at each end of the body connects the corresponding arm for pivotal movement of the arm relative to the body to enable opening and closing of the spectacles. A swivel connection associated with each arm allows the arm to be turned from a normal position to a reversed position for lying close to the body, with the arm being curved in the same direction as the body.
