Abstract

Methods of manufacturing contact lenses using ophthalmic lens molds having a molding surface comprising a thermoplastic polymer, the molding surface having a percent polarity from 3% to 20% and a surface energy from about 25 mN/m to about 40 mN/m to cast mold a polymerizable composition having a surface tension from about 20 mN/m to about 25 mN/m, wherein a surface energy differential of the surface tension of the polymerizable composition less the surface energy of the molding surface less than or equal to zero (0); and silicone hydrogel contact lens bodies so manufactured are described.
