摘要： A process for producing a plastic lens includes a step of stirring and mixing a solution including a polymerization reactive compound in a preparation tank; a step of transferring the polymerizable composition obtained in the step from the preparation tank to a lens casting mold; a step of curing the polymerizable composition; and a step of obtaining a plastic lens molded product by separating the obtained resin from the lens casting mold. The step of transferring the polymerizable composition includes a step of re-mixing the polymerizable composition discharged from the preparation tank and injecting the polymerizable composition into the lens casting mold.
