摘要： To provide a mold assembly for molding a contact lens having an excellent optical performance, which is accomplished by suppressing the axial misalignment brought about by the relative displacement between the male and female molds during the molding operation, the mold assembly has a lens molding cavity (30) defined therein when the male and female molds (1, 2) are joined together in an axial direction. A pair of mating faces (12, 22) are defined in the male and female molds (1, 2) at locations in the vicinity of outer peripheral edges of molding surface areas (11, 21) in the male and female molds (1, 2), respectively. Each face being in the form of an annular face lying substantially parallel to the axial direction. A pair of abutment faces (13, 23) are positioned radially outwardly of the mating faces (12, 22) and are, when the male and female molds (1, 2) are joined together, operable to position the male and female molds (1, 2) relative to each other in the axial direction.
