| description | The invention relates to a method for producing a molded optical part (2), in particular a lens element (2), by producing a preform (4) in a molding tool by injection molding a first plastic, and by producing at least one covering layer (6.1, 6.2) on the preform (4) by injection molding a second plastic, the temperature of the molding tool for producing the preform (4) being 30% to 60% lower than the temperature of the molding tool for producing the at least one covering layer (6.1, 6.2). |
