Abstract
The present invention relates to a method of coating a lens, such as a segmented multifocal lens. The method includes, providing a lens support (1), which is in the form of a ring, that includes a central axis (11), an outer wall (14), an inner wall (17) that is positioned between the central axis and the outer wall, an upper beveled surface (20) that converges downward toward the central axis, and a lower surface (29). The method further includes positioning a lens (3) such that an outer edge (74) of a forward surface (65) thereof abuts a portion of the upper beveled surface of the lens support. At least one coating composition is applied over the rear surface (68) of the lens, so as to form a coated lens (3′) having at least one coating layer (89) over the rear surface thereof.
