ABSTRACT:
A composition for cleaning and wetting contact lenses comprising a non-amine polyethylenoxide-containing copolymeric material having a hydrophilic-lipophile balance (HLB) of at least about 18, a surface active agent having cleaning activity for contact lens deposits and having HLB values of less than 18, and a wetting agent. Preferred embodiments of the present invention include those having from about 0.001 to about 10 weight percent of a non-amine polyethyleneoxy-containing materials, particularly those selected from: ethoxylated glucose derivatives, ethoxylated ethers of sorbitol, copolymers comprising ethyleneoxy and propyleneoxy monomeric units, and mixtures thereof. Preferred embodiments further include from about 0.001 to about 5 weight percent of the surface active agent and from about 0.1 to about 10 weight percent of a wetting agent selected from: cellulosic materials, silicone polymers containing an alkyleneoxide side chain, polyvinyl alcohols, polyvinyl pyrrolidones, and mixtures thereof.
