    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： A cleansing solution receptacle provides sterile cleansing solution when reversibly mated with a cleansing device that forces the fresh, unused contact lens solution in a manner that jets the front and back surfaces of an item with sufficient force to prevent air bubbles from clinging to surface areas of the item. Further, the cleansing device submerges the item in the fresh, unused contact cleansing solution for a controlled threshold cleansing time to ensure proper removal of contaminate build-ups on the item. Further still, according to inventive concepts, devices are automatically cleansed and dried to ensure sterility.

    摘要： A multi-chamber fluid cartridge is configured for storage of unused cleansing solution to be used by an automated contact lens cleansing device and for storage of used cleansing solution drained from the device. For example, the multi-chamber fluid cartridge may include a first chamber configured to store the unused cleansing solution and a second chamber configured to store the used cleansing solution. After being reversibly mated with the automated contact lens cleansing device, a controlled amount of the unused cleansing solution may be transferred from the first chamber to a reservoir within the automated contact lens cleansing device for performance of one or more cleansing cycles. Upon completion of the cleansing cycles, the used cleansing solution may be drained from the reservoir to the second chamber for storage until replacement of the multi-chamber fluid cartridge.
