A system for creating custom products includes an image capture device for capturing image data and/or measurement data of a user. A computer is communicatively coupled with the image capture device and configured to construct an anatomic model of the user based on the captured image data and/or measurement data. The computer provides a configurable product model and enables preview and automatic or user-guided customization of the product model. A display is communicatively coupled with the computer and displays the custom product model superimposed on the anatomic model or image data of the user. The computer is further configured to provide the customized product model to a manufacturer for manufacturing eyewear for the user in accordance with the customized product model.Type: GrantFiled: January 10, 2019Date of Patent: August 30, 2022Assignee: BESPOKE, INC.Inventors: Timothy A. Fonte, Eric J. Varady

Patent number: 11366338Abstract: Disclosed is a method for determining an optical system intended to equip a subject, the method including the steps of: —determining an index of sensitivity indicating, when the subject is placed in an environment including surfaces and/or borders forming globally a geometry of this environment; and landmarks associated with specific locations within the environment, how the subject relies on the global geometry and/or on the local landmarks of the environment to navigate within the environment; and—determining the optical system based on this index of sensitivity. The invention also relates to an ophthalmic lens and to an ophthalmic filter determined by such method.Type: GrantFiled: July 25, 2018Date of Patent: June 21, 2022Assignee: Essilor InternationalInventors: Marcia Becu, Angelo Arleo, Anne-Catherine Scherlen, Delphine Tranvouez-Bernardin, Konogan Baranton, Denis Sheynikhovich, Guillaume Tatur

Patent number: 11347085Abstract: The invention relates to systems and methods for providing custom-fitted and styled wearable items such as eyewear based on measurements made from a user-provided image that is resized using a predefined reference that includes an image of an actual wearable item. The eyewear may be provided to a user, who wears the eyewear and provides an image of the user wearing the eyewear. The user-provided images may be compared to a predefined reference (e.g., an image of the eyewear) having a known scale and/or dimension. For example, a user-provided image may be overlaid with the predefined reference and resized so that the wearable item worn by the user in the user-provided image matches (the size of) the wearable item in the predefined reference. Because the scale and/or dimensions of the predefined reference are known, one or more measurements associated with the user may be made based on the user-provided image.Type: GrantFiled: January 18, 2019Date of Patent: May 31, 2022Assignee: Electric Avenue Software, Inc.Inventor: David Barton

Patent number: 11334972Abstract: Systems, methods, and non-transitory computer readable mediums including processes to correct for distortion in images introduced by eyewear (i.e., where the facial region surrounding the eye has a boundary that doesn't match the boundary of an uncovered facial region). The correction includes segmenting images to detect eyewear covered facial regions and facial regions not covered by the eyewear and altering the covered facial regions to match the covered facial boundary to the uncovered facial boundary. Alterations include processing using a machine learning model, applying anti-refraction algorithms, scaling the covered facial region to match boundaries of the uncovered facial region, or a combination thereof.Type: GrantFiled: September 30, 2020Date of Patent: May 17, 2022Assignee: Snap Inc.Inventors: Eyal Zak, Guy Melamed

Patent number: 11324399Abstract: A method for determining a pupillary distance of an individual, includes the following steps: —displaying an object on a screen located in front of the individual, the displayed object being positioned at a location in front of one eye of the individual; —instructing the individual to look with at least the eye at the displayed object; —acquiring at least an image of a part of the body of the individual including the eye; —determining the location of a plurality of specific features in the acquired image, one of the specific features being a pupil of the eye of the individual; and —calculating the pupillary distance based on the location of the plurality of specific features. A corresponding system is also described.Type: GrantFiled: June 15, 2018Date of Patent: May 10, 2022Assignee: Essilor InternationalInventors: Charles Lebrun, Cécile Petignaud, Alvin François

Patent number: 11313759Abstract: The local refractive power and/or the refractive power distribution of a left and/or a right spectacle lens in a spectacle frame is measured in the wearing position on the head of a spectacle wearer by capturing at least two images of an eye of the spectacle wearer from different recording positions. The disclosure also relates to a computer program product having a computer program with program code and to an apparatus for carrying out the method.Type: GrantFiled: September 23, 2021Date of Patent: April 26, 2022Assignee: Carl Zeiss Vision International GmbHInventor: Carsten Glasenapp

Patent number: 11221505Abstract: In a method for checking the centration of at least one spectacle lens, the spectacle lens is arranged in a field of capture of an image capturer; at least one image of the spectacle lens is captured by means of the image capturer; and positions of functional engravings of the spectacle lens in the captured image are determined. Furthermore, at least one lens contour of the at least one spectacle lens in the captured image is determined and the centration of the spectacle lens is checked taking into account the determined positions of the functional engravings, the determined lens contour and a known, wearer-dependent target geometry of the centration.Type: GrantFiled: June 20, 2017Date of Patent: January 11, 2022Assignee: Rodenstock GmbHInventors: Markus Tiemann, Martin Dumm, Monika Füss, Roswitha Fendt, Holger Wild
