the temporary protection of polymeric articles , particularly polymeric articles with optical qualities such as ophthalmic lenses formed by the lamination of individual lens blanks , can be effected by the application of protective polymeric compositions to the surface of the polymer article , the composition being applied as a dry film or coating a film on a surface of the polymeric article . the individual lens blank is prepared for lamination or coating by application of a selective solvent to the polymeric film , the selective solvent dissolving , dispersing or otherwise removing the protective polymeric film but neither reacting with , etching or dissolving the composition of the polymeric article . the solvent even may comprise water or aqueous solutions , although c1 to c5 alcohols and alkylene glycol ethers may also be used as the solvent .
