    摘要： The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a non-crosslinkable hydrophilic polymer into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the non-crosslinkable hydrophilic polymer and to provide a disparity of about 10 N or less in mold separation force. The non-crosslinkable hydrophilic polymer has a limited miscibility with the lens-forming material low enough to successfully and timely form an intact interfacial film with a sufficient thickness at an interface between the mold and the fluid composition therein, and has a structure that minimizes entanglement of the non-crosslinkable hydrophilic polymer in the interfacial film with the polymer matrix of the formed lens.
