摘要:
A method of dip-coating a segmented multifocal lens (1) having a segment with a curved portion and a straight line portion, includes the steps of: placing the lens (1) on a basket support (21); immersing the lens (1) vertically in a coating solution bath (16); and withdrawing the lens (1) vertically from the bath (16); wherein the step of placing the lens (1) is performed such that the straight line portion of the lens (1) is in a vertical plane; and wherein, before or during the step of immersing the lens (1), the lens (1) is inclined to an inclined position between a vertical position and a horizontal position of the lens (1), in which inclined position the segment is downwardly inclined and the straight line portion of the segment remains in the vertical plane.
