    摘要： The present invention relates to a method of manufacturing a plastic lens comprising discharging a plastic lens starting material liquid from a tip opening of a discharge hole of a mixing and discharging part, the mixing and discharging part comprising a mixing chamber comprising a stirring means that stirs a plastic lens starting material liquid and the discharge hole communicating with the mixing chamber; casting the plastic lens starting material liquid that has been discharged into a casting mold, the casting mold comprising a cavity and a casting hole for introducing the plastic lens starting material into the cavity, and the plastic lens starting material being cast into the casting mold through a tip opening of the casting hole; and polymerizing the plastic lens starting material that has been cast within the casting mold to obtain a polymerized product. Before the plastic lens starting material liquid that has been cast into the casting hole reaches an interior of the cavity, the tip opening of the casting hole and the tip opening of the discharge hole are connected to secure the casting mold, and the secured state is maintained until the cavity is filled with the plastic lens starting material liquid.
