Zusammenfassung:	To prevent color change during heat bending of an individual-lens piece that comprises a functional sheet on which a protective layer formed from a transparent plastic sheet or film comprising a polyamide resin is disposed. Provided is a method for manufacturing an individual-lens piece from a functional sheet obtained by arranging a protective layer formed from a transparent plastic sheet or film via an adhesive layer on at least one side of a functional layer which is a polyvinyl alcohol-based polarizing film layer, a light control layer, or a combination thereof, wherein the method for manufacturing an individual-lens piece is characterized by including: (a) a step for manufacturing a functional sheet obtained by arranging a protective layer formed from a transparent plastic sheet or a film via an adhesive layer on at least one side of a functional layer which is a polyvinyl alcohol-based polarizing film layer, a light control layer, or a combination thereof; (b) a step for storing the functional sheet so
