To provide a method for manufacturing a polymerizable composition for an optical member in which a high-quality polymerizable composition for an optical member can be obtained without extending the manufacturing time even if froth is generated in agitating ingredients under reduced pressure.SOLUTION: A method for manufacturing a polymerizable composition for an optical member comprises: putting ingredients of the polymerizable composition for an optical member into a container; agitating the ingredients in the container; reducing the pressure in the container while agitating the ingredients; and mechanically destroying froth generated from the ingredients during the agitation in the container under the reduced pressure.SELECTED DRAWING: Figure 1 【課題】原料を減圧下で撹拌する際に泡が発生しても、製造時間が長くならず、高品質の光学部材用重合性組成物を得ることができる光学部材用重合性組成物の製造方法を提供する。【解決手段】本発明の一実施の形態である光学部材用重合性組成物の製造方法は、光学部材用重合性組成物の原料を容器内に投入し、前記容器内の前記原料を撹拌し、前記原料を撹拌しながら前記容器内を減圧し、減圧された前記容器内で撹拌を行っている間に前記原料から発生する泡を機械的に破壊する。【選択図】図１
