The present invention is directed to a composite, integral polymeric spectacle part. The spectacle part includes a first polymer member and a second polymer member. The polymer members are selected to provide desired characteristics for the spectacle part at the location of the spectacle part where the member is incorporated. In a particular embodiment, it is desirable that the first polymeric member be formed from an elastomeric polymer and that the second member be a substantially rigid polymer. The rigid polymer is preferably formed from a thermosetting polymer having a higher melting temperature than the first elastomeric member. The second rigid member is bound to the first polymer member by heat fusion during an injection molding process. In the method of the invention for forming a composite, integral, polymeric spectacle part, a first polymer member is formed into a shape conforming to a portion of the cavity of an injection mold. The entire shape of the injection mold cavity defines the finished spectacle part. After the first polymeric member is inserted into the cavity portion, a second melted polymer, which has been heated to a suitable temperature above its melting temperature, is injected into the injection mold cavity so as to fill the cavity. The first polymer member and the second injected polymer are in abutting relationship in the injection mold cavity. A composite, integral polymeric spectacle part is prepared by activation and fusion of the first preformed polymer member by the heated second polymer.

The exchangeable lens eyeglasses of the present invention include a frame including a front preferably formed as a one-piece molded plastic part having a pair of spaced rims each having an upper end and a lower end with a bridge interconnecting the rims. The bridge defines an opening. The eyeglasses further include a pair of lenses with each lens supported by a corresponding rim. Each rim has an abutment surface disposed on one side of its lens and a support rib extending on the other side of its lens and cooperating with the abutment surface to seat that lens. The support rib is discontinuous between the lower end the upper end of its rim adjacent the bridge. The eyeglasses further include a retainer preferably formed as a one-piece molded plastic part which is releasably held by the front and has a component received in the opening. The retainer overlaps both lenses and cooperates with the abutment surface of the rims to capture the lenses. Release of the retainer permits removal of the lenses from the front.

A visor type article includes a relatively rigid arcuate shaped band member, an adjustable elastic strap cooperative with the band member in a manner to encircle the wearer's head with the band member engaging the wearer's forehead, and a replaceable visor member having a marginal edge portion adapted to be releasably inserted into a slot in an outwardly extending flange on the band member so that the visor member is supported by and extends outwardly from the band member to overlie the wearer's eyes.
