    Abstract: Silicone hydrogel contact lenses are packaged in a packaging solution including an ophthalmically-acceptable concentration of a surfactant to provide a contact lens having a lower coefficient of friction compared to a control lens that is not packaged in the surfactant. The surfactant is a poly(ethylene oxide) (PEO)-containingsurfactant having a molecular weight of up to about 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.
