  • Method and kit for making ophthalmic lenses
    Publication number: 20030137634
    Abstract: In the present method, the lens maker forms a first side (2) of a semi-finished lens blank (1) to give it a desired shape. A flexible transparent wafer (4) with an optical coating (7) is then attached to the first side (2) of the blank (1). The wafer (4) serves as a substrate for the coating (7) and allows to attach the coating quickly to the newly shaped side of the blank, thereby avoiding the delays that would be required in order to apply an optical quality coating to the blank directly.
