A highly hydrous soft contact lens comprising a copolymer which contains as an ingredient a monomer having constitution similar to that of phospholipid represented by the following general formula:n wherein X isn n and R₁ is hydrogen or methyl, Y is -CH₂-, -CH₂-O-, -CH₂CH₂-O-, -CH₂CH₂CH₂-O-,n or -CH₂CH₂CH₂CH₂-O-, nn is an integer of 1-20, and, R₂, R₃ and R₄ are the same or different groups and alkyl or hydroxyalkyl of 1-8 carbon atoms. n Further, a treating solution for contact lenses which comprises a polymer containing as an ingredient the above monomer and a solvent which can dissolve the polymer. |
