ABSTRACT:
A pair of eyeglasses is 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 said one glass, with the result that both of the sidepieces will be disposed over the glasses on both sides so as to protect the glasses from impact and the like.
