A method comprises: disposing a physical landmark upon an eye of a user; capturing at least one image of the eye of the user with an image sensor while the eye is illuminated, wherein the image includes an image of the physical landmark and at least one other point on the surface of the eye outside of the cornea; processing the at least one image to obtain at least one metric of the eye of the user; and determining, based on the at least one metric, at least one parameter of a daily use contact lens to be worn on the eye of the user.

Processing a set of images is disclosed, including: determining a set of user head measurements from a set of images; and determining a fit score corresponding to a glasses frames based at least in part on comparing the set of user head measurements to glasses frame measurements associated with the glasses frames.

This invention discloses a handheld apparatus for measuring surface power or radius of prescription ophthalmic spectacle lenses, optical lenses or molds blocked with or without chuck during Rx production, and after comparing measurement results with designed data, providing correction data to the processing machines via wireless connection for correction processing if needed. The handheld apparatus integrates an optical measurement head into a monolithic optical system.

An apparatus for determining optical parameters of a user with spectacles arranged in the use position on the head of the user includes at least one projection device designed and arranged for marking a partial region of the head of the user and/or of the spectacles of the user with a light projection; at least one image recording device designed and arranged for generating image data at least from the marked partial region of the head of the user and/or of the spectacles of the user; and a data processing device with a user data determining device, which is designed to determine user data from the marked partial region of the head and/or of the spectacles on the basis of the generated image data, wherein the user data comprise spatial information in the three-dimensional space of points of the partial region of the head and/or of the spectacles, and a parameter determining device, which is designed to determine optical parameters of the user on the basis of the user data.

Systems and methods are disclosed for generating a 3D computer model of an eyewear product, using a computer system, the method including obtaining an inventory comprising a plurality of product frames; scanning a user's anatomy; extracting measurements of the user's anatomy; obtaining a first model of a contour and/or surface of the user's anatomy, based on the extracted measurements of the user's anatomy; identifying, based on the contour and/or the surface of the user's anatomy, a first product frame among the plurality of product frames; determining adjustments to the first product frame based on the contour and/or the surface of the user's anatomy; generating a second model rendering comprising the adjusted first product frame matching the contours and/or the surface of the user's anatomy.

A computer-implemented method is provided for measuring optometric values and for manipulating a glasses frame remotely in order to manufacture lenses and provide customized glasses for a person. The method includes providing aesthetic indications on the correct position of the glasses in relation to the person's head, and assessing a degree of comfort in relation to the possibility of deformation of the arms and frame.

A virtual try-on process for spectacles includes an approximate positioning and a fine positioning of a spectacle frame on a head of a user. Provided for this purpose are 3D models of the head and the spectacle frame, as well as head metadata based on the model of the head and frame metadata based on the model of the frame. The head metadata contains placement information, in particular a placement point, which can be used for the approximate positioning of the spectacle frame on the head, and/or a placement region which describes a region of the earpiece part of the frame for placement on the ears of the head. A rapid and relatively simple computational positioning of the spectacle frame on the head and a more accurate positioning using a subsequent precise adjustment can be achieved with the aid of the metadata.

A method implemented by computer means for determining at least one optical parameter of a lens of eyewear adapted for a person, the method comprising: —an image reception step, during which at least a first image and a second image are received, the first image comprising a front view of the face of the person with at least one part of an eye of the person being directly visible, and the second image comprising a front view of the face of the person with said part of the eye of the person being visible through at least part of the lens, and —an optical parameter determination step, during which at least one optical parameter of the lens is determined based on a comparison between said part on the first and the second image.

Systems and methods for creating fully custom products from scratch without exclusive use of off-the-shelf or pre-specified components. 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. The manufacturing system is configured to interpret the product model and prepare instructions and control equipment for the manufacturing of the customized product.

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.
