  • Patent number: 4563065
    Abstract: The protective glasses with tear-off lenses described consist of an eyeglass body with a fixedly mounted main viewing lens and a frame extending essentially around the entire inner extent of the eyeglass body and at a certain spacing in front of the main viewing lens, with a packet of tear off lenses with gripping tabs inserted behind this frame. The gripping tabs of all of the tear-off lenses are attached on the lower edge of the associated lens and on one side of the glasses (that is, right or left) and specifically, via a stem, the other end is attached foldable by means of a hinge to the associated tear-off lens, whereby, in the case of an inserted packet of tear-off lenses, the individual stems are folded up about their hinges and the stem of one lens is held fast in this folded-up position by means of the lens lying over it, or, in front of it.
