Abstract

A Bernoulli gripper for ophthalmic lenses includes a gripper body with a first cavity corresponding in shape to an optic zone of an ophthalmic lens and a first channel formed within the gripper body. The first channel penetrates the first cavity at one end and includes a first port in the gripper body at another end of the first channel. The first channel is enabled to supply a fluid medium from the first port to the first cavity at a first velocity such that the ophthalmic lens positioned with the optic zone in proximity to the first cavity is subject to a first pressure force against the first cavity by the Bernoulli effect.
