ABSTRACT:
A frame for eyeglasses has interchangeable lenses in which the lenses are connected to a front element of the frame which is supplied with rigid supports that contain a snap-fitting groove which creates an interference connection. The frame also includes rings on each side which yield elastically in a circumferential direction, and which attach along the peripheral edge of the lenses. The rings are pressed into the supports through elastic interference, in such a way that the lenses are connected structurally to the frame, but can be removed through the action of the snap-fitting connection.
