Beschreibung
Zusammenfassung:	Contact lens wetting solutions for reducing friction between the contact lens and ocular tissues, and maintaining such effect for a long time, are disclosed. The wetting solution is composed only of a particular ratio of a lubricant composed of copolymer (A) obtained by polymerizing a monomer composition comprising 2-(meth)acryloyloxyethyl phosphorylcholine and alkyl(meth)acrylate, a buffer, an inorganic chloride, a preservative, a chelating agent, and water. The copolymer (A) has a weight average molecular weight of 100,000 to 1,000,000, and satisfies the formula 80
