1. A Bernoulli gripper for ophthalmic lenses, the Bernoulli gripper comprising:
a gripper body with a first cavity corresponding in shape to an optic zone of an 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, wherein:
the first channel is enabled to subject 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, and
the second channel is enabled to subject 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.
