Zusammenfassung:The present invention relates to improved contact lens products which not only have initial insertion comfort but also are comfortable to wear for more than about 6 hours. The invention is achieved by packaging and storing a hydrogel lens with two or more leachable polymeric lubricants incorporated therein in a relatively viscous packaging solution including a relatively low molecular weight polyethylene glycol (PEG) and a viscosity-enhancing hydrophilic polymer. The present invention also provides methods for making contact lens products of the invention.
