PROBLEM TO BE SOLVED: To provide an apparatus and a method for molding glass lenses which can prevent poor molding of glass lenses resulting from unsuitable loading position of glass materials.;SOLUTION: In a previous step of a hot-pressing step, upper molds 1B are moved upwardly from lower molds 1C by the elevation of a push rod 7 to release glass materials G from a sandwiched state, whereby the glass materials G are settled in a proper position in mold cavities of the lower molds 1C under their own weight. Subsequently, the glass materials G are reloaded to the proper position because the upper molds 1B are moved downwardly by lowering the push rod 7, and molding die modules 1 start molding glass lenses in this reloading state all at once. Thus, poor molding of glass lenses resulting from unsuitable loading position of the glass materials G is prevented. Further, heating time in the hot-pressing step is shortened because the upper molds 1B are preheated by being brought into contact with an upper heater block 6 in the previous step of the hot-pressing step.;COPYRIGHT: (C)2008,JPO&INPIT
