Abstract
A lens molding apparatus basically includes a lens molding tool in which a pair of lens forming molds for forming outer shapes of both surfaces of a molded lens are oppositely arranged on both sides of an annular forming frame in the thickness direction to form a target space therebetween, and a molding resin is injected in the target space to form an unhardened molded lens, wherein the unhardened molded lens is hardened by irradiating the unhardened molded lens with ultraviolet rays, to form a hardened molded lens. This lens molding apparatus is characterized in that optical characteristics of the unhardened molded lens are measured by a measuring system.
