The engagement device has a first seat having a longitudinal extension and formed in a first end of a lens of a pair of eyeglasses. A second seat, also formed in the first end of the lens, has an essentially circular configuration and communicates with the first seat. The engagement device also has a longitudinal bridge connected to a second end of a temple and a cylinder connected to the bridge. The bridge and the cylinder are interposed transversely between two wings formed at the second end of the temple. The bridge is accommodated in the first seat and the cylinder is accommodated in the second seat. The walls laterally delimiting the first seat may be manufactured at mutually different angles to each other according to the desired angle of the lens with respect to the temple.
