    摘要： Embodiments of the invention relate to a method for applying an optical mark (30) to a spectacle lens (12) mounted in a spectacle frame (14). The method comprises determining an intended position of the optical mark (30) at the spectacle lens (12) based on the spectacle frame (14), and arranging the spectacle frame (14) in a marking device (10) having a marking actuator (18) and adjusting the relative position of the spectacle frame (14) and the marking actuator (18) such that an actuation axis (104) of the marking actuator (18) intersects with the spectacle lens (12) at the intended position of the optical mark (30). The method further comprises applying the optical mark (30) to the spectacle lens (12) at the intended position by using the marking actuator (18). Further embodiments of the invention relate to a used of a spectacle frame for as a positioning reference for an optical mark (30) and a marking device (10).

    摘要： Disclosed is a blocking device and method for mounting a leap block to a lens by utilizing a lifting/lowering mechanism using a magnet and a wire. The blocking device comprises: a blocking device housing (41) having a guide (31) formed therein; a leap block attachment part (21) mounted to be movable up and down on the guide (31) of the blocking device housing (41); a spring (61) having a lower end that supports the leap block attachment part (21) and an upper end that supports the blocking device housing (41), the spring (61) pushing the leap block attachment part (21) downward by an elastic force, so that a lower end of the leap block attachment part (21) protrudes below a lower end of the blocking device housing (41); a wire (11) having one end connected to a pulley (15) driven by driving means (93) and the other end connected to the leap block attachment part (21), the wire (11) pulling the leap block attachment part (21) upward when the pulley (15) rotates; a leap block (51) attached to the lower end of the leap block attachment part (21) by an attractive force of magnets; and a blocking arm (71) coupled to the blocking device housing (41) and configured to move the blocking device housing (41) up and down.
