The molded lens has a body and a protection ring extending outside from the body, and is separated from the stationary sub-mould together with the movable sub-mould. The movable sub-mould includes a mould base, a core fixed with the mould base and a pushing means for pushing the molded lens off the movable sub-mould. The pushing means is circumferentially positioned at the mould base. The upper and bottom surfaces of the protection ring of the molded lens form textures to be foggy.
