Abstract: A lens manufacturing method including a holding step of holding a lens in a lens holding fixture, and a machining step of machining a surface to be machined in the held lens. A reverse surface of the surface to be machined is machined into a non-planar shape with a first surface shape error. A lens holding surface of the lens holding fixture is machined into the same shape as the non-planar shape with a second surface shape error smaller than the first surface shape error. In the holding step, the reverse surface is brought into surface contact with the holding surface in imitation of the holding surface to correct the shape of the lens such that the reverse surface runs along the holding surface. In the machining step, the surface to be machined is machined in a state where the correction has been made by the holding step.

Abstract: In a composite molded lens, a press-formed lens body is integral with an injection-molded lens frame. The lens body has a lens portion and a flange portion surrounding the lens portion. Eight projections are radially formed on a top surface of the flange portion. The height of the projection increases toward an outer peripheral edge side of the flange portion. A recess is formed on an outer peripheral edge face of the flange portion and located at a position on a line extending from the projection. The recess increases torsional resilience of a joint surface between the lens body and the lens frame and strengthens bonding force there between.
