Abstract

A lens holder assembly (49) and method of using the lens holder assembly (49) to mark an ophthalmic lens (3) is provided. The lens holder assembly (49) comprises a stem (61) having a central axis and a first opening (5) extending along the central axis of the body (65), a second opening (7) integrated within the stem (61) such that the second opening (7) is substantially parallel to the first opening (5), and at least one illumination source positioned within the second opening (7). The illumination source is capable of emitting light through the second opening (7) for illuminating at least a portion of an ophthalmic lens (3). At least a portion of the lens (3) is placed over the first opening (5). Suction is applied to the lens (3), and a marking is applied to a surface of the lens (3).

Description

technical field [0001] The present invention relates to a lens holder and a method of marking an ophthalmic lens using the lens holder. Background technique [0002] Pad printing is one method of marking ophthalmic lenses. Such methods may include subjecting the surface of the lens to be marked to corona discharge, flame, or ionized air in order to increase the surface energy and thereby improve the adhesion of the surface to be marked. The lenses can then be marked using pad printing or screen printing with special marking inks. The ink is then dried. Thereafter, if desired, ink components can be removed with a suitable solvent. [0003] Pad printing methods can present difficulties in consistently and accurately positioning the lens relative to the frame when placing indicia, such as stamps or engravings, at desired locations on the lens, especially tinted or polarized lenses. Contents of the invention [0004] A lens holder assembly for use with a lens marking appar...
