The surfactant is a poly(ethylene oxide) (PEO)-containingsurfactant having a molecular weight of up to about ,-t 6,000 daltons, or is an alkyl aryl-containing surfactant, or is both an alkyl aryl and PEO-containing surfactant having a molecular weight of up to about 6,000 daltons. Methods of manufacturing silicone hydrogel contact lenses are also described.
