A solution for treating contact lens is provided. The solution includes about 0.01-1.0 parts by weight (pbw) of a polymer having phosphorylcholine groups, about 0.01-1 pbw of an inorganic salt, and about 100 pbw of water. The polymer has a number-average molecular weight of about 4,000 to about 1,000,000 daltons and has a structure of formula (I): n nwherein, in formula (I), m is a positive integer, n is zero or a positive integer, and R is C 2 -C 12 alkyl group or C 2 -C 12 hydroxyalkyl group. When n is a positive integer, m/n is greater than 1. |
