Abstract

PURPOSE:To facilitate removal of dirt of a lens and prevent the pollution due to bacteria, by making the thin layer of the surface of a contact lens-shaped polymer of ester acrylate or ester methacrylate hydrophilic with an alkaline aqueous solution. CONSTITUTION:A contact lens-shaped polymer obtained by polymerization of ester acrylate or ester methacrylate is treated at 30-120 deg.C for 0.5-48hr with, for example, 5-50wt% alkaline aqueous solution or is treated at 60-100 deg.C for 3-48hr with 5-90wt% aqueous solution of acid such as hydrochloric acid to form a reformed layer having thickness 0.01-50mu on the lens surface. COOH in the resin is exposed in the reformed layer, and the reformed layer is made hydrophilic. This hydrophilic lens is treated with polyhydric alcohol to convert COOH to the surface to polyhydric alcohol ester, and the lens is prevented from being clouded by Ca components or the like in the liquid. Thus, the inside of the lens is not t polluted by bacteria or the like, and thus, a lens is obtained where dirt removability, water wettability, and wear comfortableness are excellent and the durability of the reformed layer is high.
