ABSTRACT:
A method of automatic manufacture of an astigmatic contact lens having a toric portion and a ballast portion such that said ballast portion causes the toric portion of the contact lens to properly orient in the eye of the wearer. The toric lenses are manufactured by moving a pallet containing at least half of a casting cup assembly and an information tag under a filling assembly and filling half of a casting cup assembly with liquid monomer, then moving the pallet to a closing assembly and, based on information obtained from the information tag, rotating one or both halves of the casting cup assembly and closing the casting cup assembly. The liquid monomer is then cured thereby creating a toric contact lens.
