Abstract:
1. An eyeglass device, comprising: a primary spectacle frame for supporting two lenses therein, wherein the primary spectacle frame includes a left side and a right side; a first magnet disposed on the left side of the primary spectacle frame and a second magnet disposed on the right side of the primary spectacle frame; an auxiliary spectacle frame for supporting two lenses therein, wherein the auxiliary spectacle frame includes a left side and a right side; a first magnetically interacting material disposed on the left side of the auxiliary spectacle frame and a second magnetically interacting material disposed on the right side of the auxiliary spectacle frame; and at least one magnetic field blocking member, wherein the magnetic field blocking member comprises a metal, which metal results in at least partially reducing the effect of a magnetic field; wherein the auxiliary spectacle frame is held to the primary spectacle frame at least in part by magnetic attraction between the top of each magnet and the bottom of each magnetically interacting material; and wherein the magnetic field blocking member is disposed between the two sets of magnets and magnetically interacting materials when the magnetically interacting materials are below the magnets.
