  • Patent number: 10642069
    Abstract: The purpose of the present invention is to provide a method for producing an unhydrated ophthalmic lens in which the lens surface has been made hydrophilic by imparting, using a simple technique, desired water wettability and stability against the surrounding environment to the lens surface of an unhydrated ophthalmic lens comprising a silicone compound as its constituent. This purpose can be achieved by a method for producing an unhydrated ophthalmic lens having on its lens surface a hydrophilic polymer having an alkyl halide at terminal, comprising the step of bringing an unhydrated ophthalmic lens having an alkyl halide into contact with a first aqueous solution containing a first hydrophilic monomer and a metal complex to obtain the unhydrated ophthalmic lens having on its lens surface a hydrophilic polymer having an alkyl halide at terminal.
