<p>PROBLEM TO BE SOLVED: To prevent the position displacement of a material to be molded from a molding mold by matching the top of the curved surface of the a glass leans material being the material to be molded with the top of the curved surface of the molding face of a molding mold in the case of reheating press molding of glass lens. SOLUTION: In a glass lens molding method for press molding a material 14 to be molded having a curved surface shape by an upper mold 4 and a lower mold 1 having molding surfaces 15 made of curved surfaces, after the material 14 to be molded is placed on the molding surface 15 of a lower mold material 6, before the material is press molded by the upper mold 4, the lower mold material 6 is vibrated so that the material 14 to be molded is moved and aligned so as to match the center of the molding surface 15 of the lower mold material 6 with the center of the material 14 to be molded.</p> |
