ABSTRACT:
Contact lens molds and systems and methods for producing contact lens molds are described. The contact lens mold sections include two optical quality surfaces, a flange circumscribing at least a portion of the two optical quality surfaces, and an elongate member extending from the flange. Two mold sections can contact one another to form a mold assembly having a contact lens shaped cavity. The mold sections are structured to form a contact lens having an edge that does not require further physical modification before placement on an eye. Systems and methods are described which direct a molten polymeric material into cavities corresponding to the mold sections.
