A contact lens mold assembly comprising: a first contact lens mold section and a second contact lens mold section which are alignable at multiple rotational positions with respect to one another and each of which includes a molding surface (41, 31); the molding surface of one of the first and second mold sections (40, 30) shaped to provide a molded contact lens with a stabilization feature, and the molding surface of the other of the first and second mold sections shaped to provide a molded contact lens with an optical zone having a cylindrical optical correction; the molding surface (41, 31) of one of the first and second mold sections (40, 30) including an anterior contact lens-molding surface, and the molding surface of the other of the first and second mold sections including a posterior contact lens-molding surface; the first mold section includes a first set of rotational alignment features disposed angularly symmetrically on a circumference surrounding the first mold section lens-molding surface, characterized in that the second mold section includes a second set of rotational alignment features disposed angularly asymmetrically on a circumference surrounding the second mold section lens-molding surface, wherein for a desired rotational position of the first and second mold sections (40, 30), a first rotational alignment feature in the first set contacts physically a first rotational alignment feature (35a, 35b, 35c, 35f) of the second set to prevent only clockwise rotation of the first mold section, and a second, different rotational alignment feature in the first set contacts physically a second, different rotational alignment feature (35a, 35c, 35e, 35f) of the second set to prevent only counterclockwise rotation of the first mold section. a first contact lens mold section and a second contact lens mold section which are alignable at multiple rotational positions with respect to one another and each of which includes a molding surface (41, 31); the molding surface of one of the first and second mold sections (40, 30) shaped to provide a molded contact lens with a stabilization feature, and the molding surface of the other of the first and second mold sections shaped to provide a molded contact lens with an optical zone having a cylindrical optical correction; the molding surface (41, 31) of one of the first and second mold sections (40, 30) including an anterior contact lens-molding surface, and the molding surface of the other of the first and second mold sections including a posterior contact lens-molding surface; the first mold section includes a first set of rotational alignment features disposed angularly symmetrically on a circumference surrounding the first mold section lens-molding surface, characterized in that the second mold section includes a second set of rotational alignment features disposed angularly asymmetrically on a circumference surrounding the second mold section lens-molding surface, wherein for a desired rotational position of the first and second mold sections (40, 30), a first rotational alignment feature in the first set contacts physically a first rotational alignment feature (35a, 35b, 35c, 35f) of the second set to prevent only clockwise rotation of the first mold section, and a second, different rotational alignment feature in the first set contacts physically a second, different rotational alignment feature (35a, 35c, 35e, 35f) of the second set to prevent only counterclockwise rotation of the first mold section.
