Abstract: A pair of eyeglasses as provided with a mechanism on the nose bridge making it possible to turn one of the glasses around. A side piece attached thereto turns over together with one of the glasses, with the result that both of the eyepieces will be displaced over the glasses on both sides so as to protect the glasses from impact and the like when folded. Located within the bridge nose main body is a screw surrounded by a spring. At each end of the screw there are washers which provide for ease of movement between the spring and the screw. The spring is under compression at all times. Still further, the screw is tightly thread fitted into the connecting portion of the bridge so as to prevent loosening.
