Ophthalmic lens molds include first and second mold members sized and adapted to be assembled, for example interference fitted, together to define a lens-shaped cavity therebetween. At least one of the mold members includes a polar polymeric material and has a flexural modulus less than 3800 MPa.

Interference fitting polar resin ophthalmic lens molding devices and related methods

Contact lens molds and methods of producing soft cast-molded contact lens products are provided. The methods include placing a soft hydrophilic contact lens-forming composition in a cavity formed between a first mold member and a second mold member, subjecting the composition in the cavity to conditions effective to form a contact lens product from the composition, and repeating the placing and subjecting steps a plurality of times, thereby producing a plurality of soft contact lens products. At least the first mold members, and advantageously all of the first and second mold members, are injection-molded with a nucleated thermoplastic polyolefin resin having a melt flow rate in a range of 10 g/10 min to about 40 g/10 min.
