ABSTRACT:
A mold assembly for producing a plurality of contact lenses includes a front curve fixture assembly, a base curve fixture assembly and a plurality of mold cavities. The plurality of mold cavities are defined by a surface on either the front or the base curve fixture assembly and is disposed in a zig-zag manner relative to each other. Each of the plurality of mold cavities includes a retention edge for complimentary engagement with a mold. The retention edge of a first subset of the plurality of mold cavities is spaced apart from a selected fixture mating surface at a first distance and the retention edge of a second subset of the plurality of mold cavities being spaced apart from the selected fixture mating surface at a different second distance so that a plurality of molds may be placed in adjacent cavities so as to overlap the mold flanges.
