Abstract: An eyeglass attachment for interchangeably coupling with eyeglasses having at least one lens having an outer peripheral edge, and a frame including a nose bridge and two spaced-apart side ear-stems. The ear-stems are pivotally connected to the outer peripheral edges of the lens and include a distal end having a catch. A pair of removable tips connect to corresponding distal ends of the ear-stem and include a hollow cavity member having a rectangular downwardly facing notch having an abutment surface. The attachment means includes an adjustable strap means integrally coupled between a pair of clip assemblies each including a removable means for connecting with the catch of the ear-stems. The clip assemblies include a fastening means for connecting to the adjustable strap, and a pin for pivoting the removable and fastening means about an axis. The pin includes an earpiece holding means for securing a wire therein.

Abstract: An eyeglass frame is provided that includes a lens retaining part having an end piece, a temple piece, and a hinge connecting the end piece and the temple piece. The hinge includes a substantially cylindrical element having a slot, and a projection coupled to the temple piece and adapted to be received in the slot of the substantially cylindrical element. The hinge further includes a substantially cylindrical support member coupled to the end piece and adapted to accept the substantially cylindrical element and including retaining means adapted to maintain the projection in the slot of the substantially cylindrical element. A hinge for an eyeglass frame is provided. A method of assembling a hinge for an eyeglass frame is provided.

Abstract: An eyeglass frame is provided that includes a lens retaining part including first and second lens retaining sections connected by a bridge. One of the sections includes a lens receiving opening defined by a rim having a groove into which an edge of a lens is adapted to be received, and a second opening proximate the lens receiving opening and spaced apart from the bridge. The section also includes a channel extending between the lens receiving opening and the second opening. The channel is adapted to be enlarged to expand the rim such that the edge of the lens can be situated in the groove in the rim. The one section may be formed from a flexible material. The section may be formed from a single piece of molded plastic. The bridge may be substantially non-expandable. An eyewear system is provided, and a method of assembling eyewear is provided.

Abstract: Lenses are removably mounted on the brow bar of an eyeglass frame. A coupling part is fixed to the top of each lens, preferably by a rim member attached to the lens by conventional techniques. The coupling part is composed of magnetically attractive material and includes a protrusion. Each side of the brow bar carries one or more magnets to engage a coupling part and a recess to receive a protrusion to insure proper positioning of the lens relative to the brow bar. The coupling part may be retained behind, on top of, below or in front of the brow bar.

Abstract: The clip-on sunglasses assembly includes four clasps for engaging the frame of eyeglasses. Each includes a screw which secures the sunglass lens within a recess in the clasp. The end of the screw is provided with a central recess defining a circular edge. As the screw is tightened, the edge contacts the lens and forms a circular groove in the lens surface by displacing a small amount of lens material. The circular contact area distributes the stress normally concentrated at a point on the lens by a conventional screw, thereby reducing the chances of cracking the lens. Two clasps are welded to the ends of a bridge member and affixed to pre-shaped lenses at marked locations. Each clasp has a bent tail bar enclosed by a heat shrinkable tube.
