ABSTRACT:
An eyeglass device is provided which includes frames adapted for fitting on and being supported by a human wearer's head. Primary lenses are set within the frames and have an external shape. The eyeglass device also has auxiliary lenses which have an external shape which generally corresponds to the external shape of the primary lenses. First magnetic members are attached to the frames, and second magnetic members are attached to the auxiliary lenses in positions which correspond to the positions of the first magnetic members in the frames. The second magnetic members are arranged for engagement with the first magnetic members to thereby secure the auxiliary lenses to the eyeglasses.
