A solution for treating contact lens is provided. The solution includes a polymer having phosphorylcholine groups of about 0.01 to about 1.0 parts by weight (pbw), an inorganic salt of about 0.01 to about 1 pbw, and water of about 100 pbw. A number-average molecular weight of the polymer is about 4,000 to about 1,000,000 Daltons, and the polymer has a structure of formula (I):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.本發明提供一種用以處理隱形眼鏡之溶液,包含了具有磷酸膽鹼(phosphorylcholine)基之聚合物約0.01~1.0重量份、無機鹽約0.01~1重量份及水約100重量份。聚合物之數均分子量為約4,000至約1,000,000道爾頓(Dalton),且聚合物具有式(I)之結構:於式(I)中,m為正整數,n為0或正整數,R為C2~C12烷基或C2~C12羥烷基,其中當n為正整數時,m/n大於1。
