A spectacle assembly comprising: two lenses, each having formed therein a single linear nasal-side hole and a single linear temple-side hole, and a plurality of spectacle mounts (15, 29), each including a single linear block (25, 31) projecting therefrom of generally rectangular cross-section and sized to fit into one of the holes formed in an associated one of the lenses to connect the mount (15, 29) to the lens, wherein each of the blocks (25, 31) is held in the associated hole by an adhesive, the adhesive having a volume prior to setting that is the same as the volume thereof when set, the fit and the adhesive being such that each of the mounts (15, 29) is fixed to the associated lens, and the adhesive acts as a buffer between each of said blocks (25, 31) and the associated lens to substantially reduce or eliminate pressure around the assembly point of the block (25, 31) and the lens, wherein each of the holes extends in the direction of the thickness of the lens and has a cross-section that is the same as the cross-section of the block (25, 31) held therein, wherein the spectacle mounts (15, 29) include a bridge piece, wherein the bridge piece carries two such blocks, each being located at a respective end of the bridge piece, and wherein the spectacle mounts (15, 29) further include, for each of the lenses, a side piece, the block being provided at an end of the side piece, wherein the block is connected to the remainder of the side piece by a neck that is plastically deformable, wherein a gap remains between the side piece and a face of the lens in which the deformable neck is located to allow the associated side piece to vary the orientation thereof relative to the associated lens. two lenses, each having formed therein a single linear nasal-side hole and a single linear temple-side hole, and a plurality of spectacle mounts (15, 29), each including a single linear block (25, 31) projecting therefrom of generally rectangular cross-section and sized to fit into one of the holes formed in an associated one of the lenses to connect the mount (15, 29) to the lens, wherein each of the blocks (25, 31) is held in the associated hole by an adhesive, the adhesive having a volume prior to setting that is the same as the volume thereof when set, the fit and the adhesive being such that each of the mounts (15, 29) is fixed to the associated lens, and the adhesive acts as a buffer between each of said blocks (25, 31) and the associated lens to substantially reduce or eliminate pressure around the assembly point of the block (25, 31) and the lens, wherein each of the holes extends in the direction of the thickness of the lens and has a cross-section that is the same as the cross-section of the block (25, 31) held therein, wherein the spectacle mounts (15, 29) include a bridge piece, wherein the bridge piece carries two such blocks, each being located at a respective end of the bridge piece, and wherein the spectacle mounts (15, 29) further include, for each of the lenses, a side piece, the block being provided at an end of the side piece, wherein the block is connected to the remainder of the side piece by a neck that is plastically deformable, wherein a gap remains between the side piece and a face of the lens in which the deformable neck is located to allow the associated side piece to vary the orientation thereof relative to the associated lens.
