An eyeglass assembly which comprises (1) an eyeglass lens comprising a body portion and an engaging portion, and (2) a frame member which is fitted to the engaging portion, and (3) a securing member which is bonded to the engaging portion and to surfaces of the frame member which, in the absence of the securing member, are exposed to the atmosphere. In one method, the assembly is produced by applying a securing member, generally a laminar member, to exposed surfaces of the engaging portion and of the frame member fitted to the engaging portion, and securing the securing member to those exposed surfaces by an adhesive. In another method, the assembly is produced by heating and deforming part of the engaging portion of the lens so that it spreads out over adjacent surfaces of the frame member, thus forming a melt bonded securing member. In another method, the assembly is produced by supplying a polymeric precursor to adjacent surfaces of the engaging portion and the frame member, and heating and deforming the polymeric precursor so that it is melt-bonded to the engaging portion and the frame member. |
