    Abstract: A support arm assembly for a head-worn device includes a metal support arm configured to form a rear face, a bottom face, and a top face of an enclosure for a projector, thermally coupled to the projector to act as a heatsink, configured to structurally attach to a rear structural element of the head-worn device, and configured to structurally attach to an optical element holder of the head-worn device, such that the metal support arm forms a structural support joining the optical element holder to the rear structural element without placing mechanical load on the projector.

    Abstract: The present application relates to a method of identifying data for producing user-customised goggles, which contacts the face of the user defined by a contacting surface on said face, when the user uses said goggles, the method comprising the steps of, receiving an input of 3D-data defining the contour of the face of the user and defining the dimension of the face of the user at least in an area around the eyes of the user, identifying contact areas on the contacting surface, and providing structure-data based on said input of 3D-data and said contact areas, where the structure-data is used for designing at least the part of said goggles, which is adapted to contact the face of the user. The application further relates to a system for producing a pair of user-customised goggles, a pair of user-customised goggles, and a user contacting structure of a pair of user-customised goggles.

    Abstract: An eyeglass managing system determines process parameters for manufacturing at least part of an eyeglass including a lens and a frame. In this eyeglass managing system, an electronic system includes: —a receiving unit adapted to acquire lens data describing an initial lens and frame data describing an initial frame; —a processing unit adapted to identify, based on the lens data and on the frame data, modification parameters deriving from the interaction between the initial lens and the initial frame; and—a transmitting unit adapted to transmit a list of proposed modifications based on the identified modification parameters. The receiving unit is further adapted to acquire a response to at least one proposed modification; the processing unit is further adapted to determine, based on the acquired response, process parameters of an additive manufacturing process for manufacturing the lens or the frame.

    Abstract: A system and method of predicting fit of a wearable device from image data obtained by a computing device together with position and orientation of the computing device is provided. The system and method may include capturing a series of frames of image data, and detecting one or more fixed features in the series of frames of image data. Position and orientation data associated with the capture of the image data is combined with the position data related to the one or more fixed features, to extract depth data from the series of frames of image data. A three-dimensional model of is generated based on the extracted depth data. The three-dimensional model is processed by a simulator and/or a machine learning model to predict fit of the wearable device for the user.

    Abstract: A method for determining a contour of a frame groove in a rim of a spectacle frame includes illuminating the rim, capturing a plurality of images of the illuminated rim from different predetermined perspectives, evaluating the captured images, and determining a spatial curve of the frame groove based on the evaluated images. The rim is illuminated along the entire circumference of the rim by directed illumination. Moreover, the evaluation of the captured images includes assigning each portion contained in the captured images to a respective surface element of the frame groove on the basis of at least one of the following properties: shadowing of the respective portion, brightness of the respective portion and phase angle of the illumination of the respective portion. Moreover, an apparatus, a computer program, a method for grinding a spectacle lens, and a computer-implemented method for determining a geometry of a spectacle lens are disclosed.

    Abstract: The local refractive power or the refractive power distribution of a spectacle lens is measured. A first image of a scene having a plurality of structure points and a left and/or a right spectacle lens of a frame front is captured with an image capturing device from a first capture position having an imaging beam path for structure points, which extends through the spectacle lens of the frame front. At least two further images of the scene are captured with the image capturing device from different capture positions, one of which can be identical with the first capture position, without the spectacle lenses of the spectacles or without the frame front containing the spectacle lenses having the structure points imaged in the first image, and the coordinates of the structure points in a coordinate system are calculated from the at least two further images of the scene by image analysis.
