Methods of applying a coating to an optical surface

A method for applying a coating to an optical surface of an optical lens, comprising the steps of:

• a. placing a coating solution in a cliche of a cliche plate;
• b. transferring the coating solution from the cliche to a transfer pad;
• c. pressing the transfer pad to the optical surface so as to transfer the coating solution from the transfer pad to the optical surface;
• d. irradiating the coating solution associated with the optical surface at a wavelength of microwave so as to form a coating layer on the optical surface;
• and
• e. curing the coating layer to form a coating on the optical surface by radiation outside the wavelength range of microwave.

A method for applying a coating to at least one optical surface of an optical lens, comprising the steps of:

• a. placing a coating solution in a cliche of a cliche plate;
• b. transferring the coating solution from the cliche to a transfer pad;
• c. providing a front mold and a back mold each having a facing inside surface;
• d. pressing the transfer pad to each of the facing inside surfaces of the front mold and back mold so as to transfer the coating solution from the transfer pad to each of the facing inside surfaces, respectively;
• e. irradiating the coating solution associated with each of the facing inside surfaces at a wavelength of microwave so as to form a coating layer on each of the facing inside surfaces;
• f. positioning the front mold and the back mold whose facing inside surfaces are a negative image of the surfaces of an optical lens to be formed at a proper distance and rotational orientation relative to each other, both the front mold and back mold having an edge;
• g. closing the edges of the front mold and back mold with a closure member to define a molding cavity;
• h. injecting a fluid lens-forming material into the molding cavity;
• and
• i. curing the fluid lens-forming material by radiation outside the wavelength range of microwave so that the fluid lens-forming material is hardened to form the optical lens and each of the coating layers on the inside surfaces of the front mold and back mold is transferred to and hardened to be bond on a corresponding surface of the optical lens.

A method for applying a coating to at least one optical surface, comprising the steps of:

• a. placing a screen over the optical surface;
• b. applying some coating solution to the screen;
• c. transferring some coating solution to a transfer pad;
• d. pressing the transfer pad against the screen so as to transfer the coating solution from the transfer pad to the screen and to the optical surface;
• and
• e. irradiating the coating solution so as to form a coating layer on the optical surface.
