A method for calibrating lens grippers prior to use of the grippers in a lens manufacturing line includes providing a remote gripper calibration tool having an assembly plate and a Z-directional position sensor; providing a master gripper having a length dimension terminating in a tip, the length dimension being predetermined to match a desired final extension length of a lens gripper; mounting the master gripper to the assembly plate; measuring the Z-directional position of the tip of the master gripper with the Z-directional position sensor; unmounting the master gripper from the assembly plate; mounting a lens gripper to be calibrated to the assembly plate, the lens gripper having a tip, and calibrating the lens gripper by adjusting the final extension length of the tip of the lens gripper to a predetermined position relative to the measured Z-directional position of the tip of the master gripper.

A method for transporting a blister strip of ophthalmic lenses: only one single blister strip is provided at a start location and one magazine compartment of two magazine compartments contains n blister strips while the other magazine compartment contains n+1 blister strips, the single buster strip is picked up at the start location by one of the gripper units of a first gripper and is transported into that magazine compartment containing the n blister strips, by moving the first gripper to that magazine compartment containing the n blister strips and releasing the single blister strip from the first gripper into that magazine compartment, or by moving the first gripper to a hand-over station and releasing the single blister strip from the first gripper into the hand-over station, transporting the single blister strip from the hand-over station into that magazine compartment containing the n blister strips using a second gripper.

A method for determining whether a sealing area of a primary packaging container for an ophthalmic lens is unacceptable for properly sealing a foil to the sealing area is disclosed. The method involves comparing the temperature of an infrared image of the sealing area to a reference temperature to determine if the difference in temperature exceeds a predetermined threshold.

A packaging container () for a contact lens comprises a shell (). The shell () comprises a cavity () having a drop-shaped perimeter (), and a flange () having a flat upper surface () extending around the drop-shaped perimeter () of the cavity () in an upper surface plane (). The cavity () comprises a bowl portion () including an at least partially spherical section () for accommodating the contact lens, and a chamfer portion () surrounding the bowl portion (). The chamfer portion () is arranged between the bowl portion () and the drop-shaped perimeter () of the cavity () and includes a tapered outlet section () forming a tip towards the flange () to facilitate removal of the contact lens from the cavity ().
