A solution for treating a contact lens and a contact lens packaging system are provided. The solution includes about 0.01 to about 1.0 parts by weight (pbw) of a polymer having phosphorylcholine groups, about 0.005 to about 0.05 pbw of a hydrophilic molecule, about 0.01 to about 1.0 pbw of an inorganic salt, and about 100 pbw of water. A number-average molecular weight of the polymer is about 4,000 to about 1,000,000 daltons. The polymer has a structure of formula (I):wherein, in formula (I), m is a positive integer, n is zero or a positive integer, and R is C2-C12 alkyl group, or C2-C12 hydroxyalkyl group. When n is a positive integer, m/n is greater than 1. Moreover, a number-average molecular weight of the hydrophilic molecule is about 10,000 to about 5,000,000 daltons. The hydrophilic molecule is hyaluronic acid (HA) or hyaluronate salt.
