发明名称 Mold assembly for forming ophthalmic lens
摘要 Lens mold assembly including a first and a second mold cooperating with each other to define a mold cavity for molding an ophthalmic lens with the first and second molds being held in line contact with each other at a radial position, wherein at least one of the two molds consists of a central molding portion located radially inwardly of the radial position, and an outer rim portion located radially outwardly of the radial position, the central molding portion cooperating with the other mold to define the mold cavity, the above-indicated at least one mold having a mold surface which is opposed to a mold surface of the other mold when the two molds are assembled together, the mold surface of the at least one mold consisting of a central lens-forming region in the central molding portion, and an outer peripheral non lens-forming region in the outer rim portion, at least a part of the lens-forming region adjacent to the radial position providing a concave portion, while at least a part of the outer peripheral non lens-forming region adjacent to the radial position providing a convex portion.
