Abstract
A method of modifying a surface of an ophthalmic lens, includes the steps of: generating plasma at an atmospheric pressure between electrodes of a plasma generating device; and blowing the plasma from the plasma generating device by introducing a gas between the electrodes. The ophthalmic lens, which is located outside the plasma generating device, is irradiated with the plasma blown out from the plasma generating device to modify the surface of the ophthalmic lens to form a final ophthalmic lens product.
