ABSTRACT:
An eyeglass device may include a primary spectacle frame and an auxiliary spectacle frame (each of which frames may support respective lenses). The primary spectacle frame may include two legs pivotally coupled to two side extensions. Further, the auxiliary spectacle frame may include two arms for engagement with the primary spectacle frame. In addition, each of the primary spectacle frame and the auxiliary spectacle frame may include one or more magnetically interacting materials (e.g., one or more magnets and/or one or more ferrous metals). The one or more magnetically interacting materials of the primary spectacle frame may be disposed in the vicinity of a bridge of the primary spectacle frame and/or in the vicinity of one or both of the side extensions. Likewise, the one or more magnetically interacting materials of the auxiliary spectacle frame may be disposed in the vicinity of a bridge of the auxiliary spectacle frame and/or in the vicinity of one or both of the legs. The magnetically interacting materials of the primary spectacle frame and the auxiliary spectacle frame may cooperate to secure the spectacle frames together (e.g., so as to prevent the auxiliary spectacle frame from moving downward and/or upward relative to the primary spectacle frame). In addition, a magnetic field blocking member may be disposed adjacent at least a top or a bottom of at least one of the magnetically interacting materials (e.g., to aid in proper placement of the auxiliary spectacle frame relative to the primary spectacle frame).
