Claim 16:
17. A method for gripping ophthalmic lenses, the method comprising:
placing a gripper body in proximity to an ophthalmic lens, the gripper body having:
a first cavity corresponding in shape to an optic zone of the ophthalmic lens;
a first channel formed within the gripper body, the first channel penetrating the first cavity at a first end of the first channel; and
a second channel formed within the gripper body, the second channel penetrating the gripper body at a first end of the second channel;

subjecting the ophthalmic lens positioned with the optic zone in proximity to the first cavity to a first pressure force against the first cavity by a Bernoulli effect through the first channel; and
subjecting at least a portion of the ophthalmic lens positioned in proximity to the second channel to a second pressure force different from the first pressure force through the second channel.
