Publication number: 20220252861Abstract: Electrowetting optical devices can comprise a first electrode at least partially circumscribing a first optical window and a second electrode at least partially circumscribing a second optical window. The second optical window may be aligned with the first optical window in a direction of the optical axis. A central region may be defined by a projection of a footprint of the second optical window. An interface between a first liquid and a second liquid that may be disposed within a containment region may form a lens. In some embodiments, a thickness of a second dielectric portion at least partially circumscribing the central region may be greater than a thickness of a thirst dielectric portion within the central region. In some embodiments, a capacitance per area of the device upon application of a maximum operating voltage may be in a range from about 0.1 pF/mm2 to about 3.5 pF/mm2.Type: ApplicationFiled: June 24, 2020Publication date: August 11, 2022Inventors: Jerome René Broutin, Benjamin Jean-Baptiste Francois Burger, Aude Contet, Géraldine Denise Juliette Malet-Vasseur, Nicolas Gilbert Jose Samper

Patent number: 9411170Abstract: The visual perception of a lens wearer is not only along the gaze direction, but also has a non-zero transverse extension, which is called perceptual span. Perceptual span is skewed to extend further in the reading direction, i.e., the line portion to be read next relative to the line portion that was just read. A technique is provided that determines a pair of progressive ophthalmic lenses that take such perceptual span into account.Type: GrantFiled: June 28, 2013Date of Patent: August 9, 2016Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)Inventors: Björn Drobe, Paulyn Ng Hwei Kien, Aude Contet

Patent number: 9360684Abstract: A method for determining target optical functions for a pair of ophthalmic lenses is provided, the method comprising steps of: generating a first target optical function (OFT1) for a first lens of the pair based at least on data relating to a first eye, generating a second target optical function (OFT2) for a second lens of the pair based at least on data relating to the first eye. This method makes it possible to obtain optical functions having improved symmetry. Thus, when using the target optical functions in an optical optimization method, lenses with improved binocular properties can be obtained. The comfort of the wearer of the pair of lenses is thus improved.Type: GrantFiled: February 17, 2012Date of Patent: June 7, 2016Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)Inventors: Aude Contet, Hélène De Rossi

Patent number: 9307899Abstract: A process for determining a pair of personalized progressive ophthalmic lenses. and a computer program product associated to these processes. Right-handed persons and left-handed persons behave very differently when executing certain near vision tasks, such as writing on a sheet of paper. However, current lens designs do not take into account these behavior differences. The comfort of wearing a pair of ophthalmic lenses can be improved for the wearer for whom the lenses are intended by adapting his near vision according to his handedness.Type: GrantFiled: June 28, 2013Date of Patent: April 12, 2016Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)Inventors: Damien Paille, Benjamin Rousseau, Aude Contet, Isabelle Poulain, Stéphanie Vialet, Farid Karioty
