Highly hydrous soft contact lens and a treating solution for contact lenses

摘要

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: IMAGE> Y is CH2, CH2O, CH2CH 2O, CH2CH2CH2CH2O, n 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. 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.
