Beschreibung
Zusammenfassung:	A contact lens and a manufacturing method thereof are provided. The contact lens includes a lens and a hydrophilic polymer layer. The hydrophilic polymer layer and the lens are entangled with each other. The hydrophilic polymer layer and the lens form an interpenetrating polymer network or a semi-interpenetrating polymer network. The hydrophilic polymer layer is formed by polymerizing an initiator adsorbed on the lens with at least one hydrophilic vinyl monomer. The contact lens has excellent hydrophilicity. Since the manufacturing process of the contact lens is simple, the manufacturing efficiency can be improved, and the manufacturing cost can be reduced. Moreover, the manufacturing method can be applied to lenses made of various materials and used for their surface modification, so it is widely applicable.
