Abstract
Eyeglass assemblies including an eyeglass lens having an engaging portion. Under typical conditions of use, the engaging portion is maintained in contact with an eyeglass frame member by means of a removable bonding member (RBM). Under selected atypical ambient conditions, the RBM changes so that the engaging portion and the frame member can be separated. The engaging portion can extend from the lens, or can be a recess in the lens. The RBM can be a suitable adhesive (RBA), or a component composed of a shape memory metal (RBSMA) or a material which softens when subjected to heat or other atypical condition. The engaging portion can be shaped and treated to reduce stresses therein. Similarly, the open ends of an eyeglass rim can be maintained in contact with each other under typical conditions of use by an RBA or an RBSMA so that the rim is positioned around an eyeglass lens, but can be released under selected atypical ambient conditions.
