A detachable shelter frame is constructed to mount on a primary spectacle frame by two resilient mounting devices which are extended from two inner sides of two auxiliary lenses respectively. Each of the resilient mounting devices includes a resilient arms extending rearwardly from the shelter frame and an engaging member which is connected to the resilient arm and extended to press against a rear side of the primary bridge of the primary spectacle frame, wherein the two resilient arms substantially pull the two engaging members towards the primary spectacle frame so as to apply an urging pressure against the primary spectacle frame for holding the frame body of the primary spectacle between the primary spectacle frame and the engaging members, so as to securely mounting the shelter frame in front of the primary spectacle frame.
