A method for binding a lens to a frame, wherein the lens has:
- 1) a first surface located off the eye side;
- 2) a second surface located toward the eye side;
- 3) an inner hole provided at the inner edge through the first and second surfaces for connecting to the frame over the nose;
- and
- 4) an outer hole provided at the outer edge through the first and second surface for connecting to the frame over the ear,
- wherein the frame has:
- 1) a L-shaped member having a front end, a rear end, a front hole provided at the front end, and a rear hole provided at the rear end, wherein the front end and the front hole are adapted to be connected to the outer hole of the lens, wherein the rear end and the rear hole are adapted to be connected to the temples;
- and
- 2) a bridge member having a center bar and two holes provided at the ends of the center bar, comprising steps of:
- a) aligning one of the holes of the lens with one of the holes of the frame;
- b) piercing a peg through the aligned holes of the lens and the frame;
- c) resting the aligned lens and frame on a bench;
- d) cutting the peg at a predetermined length;
- e) heat-and-melting the stub of the peg with a heating device;
- and
- f) molding the molten stub of the peg with a predetermined shape.
