ABSTRACT:
A lens holding structure for brackets of frameless spectacles includes a bracket which has a bolt extended therefrom with an axial key way formed thereon and a holder which has a screw hole on one end with an axial jutting key to couple with the key way, and an arm on another end thereof. The lens is held on the ends by one end of the bracket and one side of the arm. The bracket and the arm have respectively a clamping section. One or all of the clamping sections has a coarse means. Thus the holder may be moved by turning a nut coupled on the bolt to clamp the lens steadily between the bracket and the holder without drilling coupling holes on the lens.
