Abstract: A method of cleaning deposited material from a molding surface (10) of a mold (1) for forming ophthalmic lenses, including bringing a cleaning head (20) into contact with the molding surface (10), the rotational axis (22) of the cleaning head (20) being arranged normal to the molding surface (10), rotating (220) the cleaning head (20) around the rotational axis (22) while maintaining the contact between the cleaning head (20) and the molding surface (10), moving the cleaning head (20) to perform a precession motion (110) around a central normal (11) on the molding surface (10), while rotating (220) the cleaning head (20) around the rotational axis (22) and while maintaining the contact between the cleaning head (20) and the molding surface (10). During the precession motion (110) the rotational axis (22) includes an inclination angle (?1,?2) with the central normal (11) on the molding surface (10).

Abstract: A method for avoiding the entrapment of air bubbles (5) in a lens forming material (4), in particular in a low viscosity lens forming material, in an ophthalmic lens manufacturing process using mold halves (2, 3) each having a lens forming surface (21, 31) comprises electrostatically charging (60) a lens forming surface (21, 31) of the mold half (2, 3) prior to the lens forming surface (21, 31) coming into contact with the lens forming material (4).

Abstract: A gripper (1) for a contact lens (CL) includes a gripper head (10) having a bearing surface (11), the bearing surface (11) having at least one opening (110) through which underpressure can be applied in order to suck the contact lens (CL) against the bearing surface (11) and through which overpressure can be applied in order to release the contact lens (CL) from the bearing surface (11). The gripper further includes a detection opening (111) in the bearing surface (11) through which a separate underpressure can be applied.

Abstract: An ophthalmic lens , e.g. a contact lens, is centered in a concave trough (10) of an inspection cell (1) which is filled with liquid (W). The inspection cell (10) has a channel (11) which is in communication with the concave trough (10). Centering of the ophthalmic lens is achieved by applying a pulse (P) of a fluid to the liquid (W) so as to whirl up the ophthalmic lens (CL) and by allowing the ophthalmic lens (CL) to settle down in the center of the concave trough (10).
