A lens is dimensioned for receipt in the lens opening. The lens has a key selectively interconnecting the lens to frame in a lens opening. The key has a protrusion received in a complementary groove in the frame around the lens opening, and a tab along a minor portion of the key that is received in a notch in the frame groove which provide a region where less force is required to mount or remove the lens relative to the frame. ## Claims ### Claim 1 An eyeglass assembly comprising: a frame having first and second lens openings formed therein, the frame including one of a groove and a protrusion around the lens openings; at least one lens dimensioned for operative association with at least one of the first and second lens openings, the lens including one of a groove and a protrusion; and a key selectively interconnecting the lens to the at least one of the first and second openings in the frame, the key including (i) an other of a protrusion and a groove along an inner perimeter that mates with the one of the groove and protrusion of the lens, and (ii) an other of a protrusion and a groove along an outer perimeter that mates with the one of the groove and protrusion of the frame, wherein the key has a tab protruding outwardly from a remainder of the key. ### Claim 2 (depends on 1) The eyeglass assembly of claim 1 wherein the key has a fixed thickness. ### Claim 3 (depends on 2) The eyeglass assembly of claim 2 wherein the key is fabricated from at least one of an epoxy, polymer, composite, or metal material. ### Claim 4 (depends on 1) The eyeglass assembly of claim 1 wherein the key has an inner perimeter configured for receipt in a similarly configured lens groove. ### Claim 5 (depends on 4) The eyeglass assembly of claim 4 wherein the key extends around the entire perimeter of the lens. ### Claim 6 (depends on 1) The eyeglass assembly of claim 1 wherein the inner perimeter of the key has a cross-sectional configuration and dimension that is one of domed or triangular for receipt in the complementary-shaped lens groove. ### Claim 7 (depends on 1) The eyeglass assembly of claim 1 wherein the key has an outer perimeter configured for receipt in a frame groove around the lens opening. ### Claim 8 (depends on 7) The eyeglass assembly of claim 7 wherein the key extends around the entire perimeter of the frame. ### Claim 9 (depends on 1) The eyeglass assembly of claim 1 wherein the outer perimeter of the key has a cross-sectional configuration and dimension that is one of domed or triangular for receipt in the complementary-shaped lens groove. ### Claim 10 (depends on 1) The eyeglass assembly of claim 1 wherein the frame includes a notched portion configured to receive the key tab. ### Claim 11 (depends on 10) The eyeglass assembly of claim 10 wherein the notched portion of the frame is located adjacent a nose bridge portion thereof. ### Claim 12 (depends on 11) The eyeglass assembly of claim 11 wherein the notched portion of the frame is located on an inner surface thereof whereby the key tab is not visible along an external surface of the frame when the eyeglass assembly is worn by an associated user. ### Claim 13 (depends on 1) The eyeglass assembly of claim 1 wherein the tab is provided over only a minor portion of the key. ### Claim 14 A method of forming an eyeglass assembly having removable lenses comprising: providing at least one removable eyeglass lens; providing a frame having at least one lens opening; forming a key to a rim of each eyeglass lens; providing a tab along a portion of the key that cooperates with a notched region in the frame; and inserting the lens into the frame, with less force required along the tab and notched region than a remainder of the eyeglass assembly. ### Claim 15 (depends on 14) The method of claim 14 further comprising forming a groove along a lens rim that receives a portion of the key. ### Claim 16 (depends on 14) The method of claim 14 further comprising forming a groove within the frame that receives a portion of the key. ### Claim 17 (depends on 16) The method of claim 16 further including positioning the notched region of the frame groove in the bridge piece of the frame. ### Claim 18 (depends on 14) The method of claim 14 including positioning the tab where the lens adjoins the bridge piece of the frame.
