Abstract
An eyeglass assembly includes a frame having first and second lens openings. 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.
