PROBLEM TO BE SOLVED: To provide a method for molding a plastic lens capable of filling a liquid molding material for a plastic lens into a mold by leaving no bubbles as much as possible. SOLUTION: A mold 11 is constructed in the first place by keeping a first and a second lens mold forms 12 at a predetermined distance with a tape 14. Thereafter, an infusing opening 45 is first formed to the set mold 11 with a cutter 26 at the place out of alignment to the right from the upper center position P of the mold 11 on the figure. Successively, an infusing nozzle 27 is inserted into the infusing opening 45 to begin with infusing a raw material monomer. After proceeding a measure of infusion, the mold 11 is turned to transfer the infusing opening 45 to the upper center position P. The nozzle 27 is transferred also accompanying the infusing opening. Then, infusing operation is restarted to fill an inner space 18 completely with the raw material monomer. After the completion of the filling operation, the raw material monomer is cured with heat according to the ordinary method. COPYRIGHT: (C)2008,JPO&INPIT |
