ABSTRACT:
Spectacle frames are provided for use with either prescription lenses, safety lenses, or the like, the frames having a lens-holding substructure with two lens-holding rims joined at the center section by a bridge piece, and two head-engaging members pivotably attached at or near the bridge piece to a top surface thereof, and extending upwardly and around to the side of a wearer's head, the head-engaging members terminating at ear-engaging portions. The pivotable attachment of the head-engaging members to the lens-holding substructure is effected by snap-fitting a cylindrical pin having a ball element at its end, which extends from a forward end of each head-engaging member, into one of a pair of cylindrical bores, each terminating at a spherical socket, which are disposed at and extend into the lens-holding substructure at or near the bridge piece.
