ABSTRACT:
A spectacles set includes a primary spectacle frame and a detachable shelter frame configured for mounting in front of the primary spectacle frame. The detachable shelter frame includes a shelter frame for supporting two auxiliary lenses and a pair of magnetic attaching arrangements connected to the shelter frame. A pair of magnetic adaptor pads are used to attach to the nose support, or near the nose support portion, of the primary spectacle frame, so that the magnetic attaching arrangements can be applied to a primary spectacle frame even though the primary spectacle frame was not originally designed or produced to match with a shelter frame.
