Abstract: Eyeglass assemblies comprise (1) a shear pin which secures a frame member (1, 12) to a lens (11) or two frame members to each other, and/or (2) components which are substantially more transparent to ultraviolet radiation than the lens material, and/or (3) auxiliary members (14) which extend upwards from the lenses and facilitate correct positioning of the eyeglass assembly.

Abstract: An eyeglass assembly comprising a frame member comprising a tubular terminal portion (2), and eyeglass lens (11) having an engaging portion (112) to which the frame member is fitted, and a composition (219) which (i) provides at least part of an interface between the engaging portion and the frame member and (ii) extends at least part way into a passage (215, 115) which passes from the interface to an exposed face of the frame member or of the lens. The composition can be a UV-cured adhesive which can be weakened by heat so that the assembly can be easily disassembled.
