ABSTRACT:
An improved eyeglass temple for retaining eyeglasses on the head of a wearer is provided. The temple includes an engaging portion that extends from a second end of the temple to a support section. An ear stem extends through the engaging portion and has a cross-sectional dimension less than the cross-sectional dimension of the support section, adjacent to the engaging portion. A resilient, elastomeric ear piece is integrally formed on the ear stem to form the engaging portion. The elastomeric ear piece provides an increased coefficient of friction between the engaging portion and the head and ear of the wearer, to prevent inadvertent relative movement between the temple and the wearer. The elastomeric ear piece is formed on the ear stem at such a temperature that the molecular structure of the elastomeric material comprising the ear piece cross-links to the molecular structure of the material comprising the temple, preferably a hard plastic, to integrally bond the ear piece to the ear stem. Thus, the ear piece of the invented temple does not detach from the ear stem, nor does it move about thereon. Further, the ear piece is sufficiently deflectable to inhibit the ear piece from exerting excessive pressure on the head and ear of the wearer, for increasing the comfort of the wearer, while securely retaining the temple on the wearer's head.
