09804410 · 2017-10-31 ·

Eyewear can include lenses having perimeters that are customized for an intended wearer. The perimeter of the lenses can be determined based on anatomical features of the wearer's face, field of vision, or other parameters specific to that individual. The perimeter may also be configured to accommodate one or more of: a component configured to be coupled to the eyewear, an item configured to be worn by the wearer in conjunction with the eyewear, or a projected line of sight of the wearer. A provisional lens perimeter obtained may be modified in curvature and/or size to arrive at a desired final lens perimeter, based for example on stylistic preferences or to accommodate external elements affecting the perimeter and/or curvature of the lens. Customized lenses can be fabricated based on the determined lens perimeters. The customized lenses can be assembled into completed eyewear that is customized for a wearer, for example having shapes, sizes, and designs not otherwise possible.

EYEWEAR FRAME CUSTOMIZATION USING MACHINE LEARNING
20220057658 · 2022-02-24 ·

A design system generates a design for an eyewear frame customized for a user. The eyewear frame provides audio content to the user. The design system captures anthropometric data of the user. Using machine learning techniques, the design system determines features of the user from the anthropometric data and generates a three dimensional (3D) geometry of the portion of the user's head. A design for the customized eyewear frame is generated based on the 3D geometry of the portion of the user's head. The design of the customized eyewear frame includes design parameters that describe a shape of a coupling element that ensures the eyewear frame is customized to the user's head.

Method and device for measuring data for fitting an ophthalmic lens in a frame for a given individual

Disclosed is a method for measuring data for fitting an ophthalmic lens in a frame for a individual, including the following steps: a) placing the individual in a natural posture; b) displaying a visual target with adjustable position in the field of view of the individual; c) having the individual equipped with the frame adjust the position of the visual target in order to place it straight ahead from him; d) determining the intersection, with a surface representative of the lens once placed in the frame, of the line of sight of the individual looking at the visual target with its adjusted position and determining the data based on the intersection determined.

A METHOD FOR ORDERING AN OPTICAL EQUIPMENT

A method, implemented by computer means, for ordering an optical equipment comprising at least a spectacle frame suitable for a wearer, the method comprising: a wearer data providing step during which wearer data relative to a wearer parameter are provided, a optical equipment data providing step during which optical equipment data relative to at least the spectacle frame of an optical equipment selected by the wearer are provided, a mounting data determining step during which mounting data representative of the spectacle frame being mounted on the wearer's head are determined by taking into account at least said wearer's data and said optical equipment data, a display step during which the mounting data are displayed in a visually understandable mode.
