Abstract
Provided are a contact lens care preparation capable of imparting durable surface lubricity and amebic adhesion inhibitory effect to a contact lens surface through a simple treatment, and a contact lens packaging solution utilizing the same. The contact lens care preparation is composed of a solution containing 0.01 to 2 weight/volume % of a polymer having particular monomer units with a phosphorylcholine-like group, particular (meth)acrylamide derivative units, and particular monomer units with a hydrophobic group at a particular ratio, and a weight average molecular weight of 5,000 to 2,000,000, and is useful as a contact lens packaging solution.
