Abstract
A pair of novelty eyeglasses includes a frame for supporting them on the wearer's head and a pair of transparent lenses. The frame includes a pair of support earpieces connected by hinges to the frames. Two light emitting diodes or LEDs are secured to the frame, one adjacent each lense and connected to a portable source of power, such as small batteries, mounted in one of the earpieces. A hinge switch, defined at one of the hinges connecting one of the earpieces to the frame, must be closed by moving the respective earpiece to the open position before the LEDs can be actuated. A manually actuatable switch is secured to the frame in series with the batteries and the light emitting diodes. The manually actuatable switch can be selectively closed by the user to energize the LEDs thereby creating a novel effect.
