Eyeglass assemblies include an eyeglass lens having an engaging portion. The junction between the body portion of the lens and the engaging portion can consist essentially of smoothly curved surfaces. The engaging portion can be extend from the periphery of the lens or can be a recess in the lens. In some assemblies, 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 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.
