  • Publication number: 20240115374
    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.

  • Patent number: 9274350
    Abstract: An ophthalmic lens (1) has a front surface (2) and a rear surface, each of the front and rear surfaces comprising a central optical zone (4) which is surrounded by a peripheral zone (3). The ophthalmic lens (1) further comprises a unique lens identification code which is arranged in the peripheral zone (3) of one of said front and rear surfaces. The unique lens identification code has the form of an N×M dot matrix (5) comprising N rows and M columns of matrix elements (50), and the N×M dot matrix (5) represents a binary code.
