The method includes applying glue onto one surface of one component of the tool placed in a support of a first supporting member and/or onto one surface of another component of the tool placed in a support of a second supporting member while the support of the first supporting member and the support of the second supporting member are side by side; then driving the first supporting member and the second supporting member relative to one another to a second position where the support of the first supporting member and the support of the second supporting member are aligned; and then pressing the first supporting member and the second supporting member towards one another for applying onto each other the one surface of the one component and the one surface of the another component.

The invention concerns a method of manufacturing an ophthalmic lens, comprising the steps of providing, mounting and blocking a substrate (10) on a machining support unit (65), surfacing an upper face (12) of said substrate, edging a peripheral edge (13) of said substrate, wherein said machining support unit comprises a surfacing member (40) and an edging member (30) which are separable, said surfacing member having a cavity (51) in which said edging member is located during said step of surfacing, said surfacing and edging members being configured so that said substrate is mounted and blocked on said machining support unit in a first predetermined position for the surfacing and the edging and, between said steps of surfacing and edging, the method comprises the step of withdrawing said surfacing member from said machining support unit by retaining said substrate on said edging member.

The method includes a step of applying glue including carrying out with a pad printing machine a sequence of steps in which is driven a transfer pad from a glue taking position to an applying position in which the distal surface of the transfer pad is in contact with one surface of one component of the tool and in which is simultaneously driven another transfer pad from a glue taking position to an applying position in which the distal surface of the another transfer pad is in contact with one surface of another component of the tool, whereby the glue is applied simultaneously to the one surface of the one component and to the one surface of the another component.

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.

Disclosed is a method of determining a guideline for trimming an optical lens to be trimmed in view of its mounting in a spectacle frame in which is mounted at least one reference optical lens, including: removing the reference optical lens; fixing the removed reference optical lens on a support of a machine for acquiring images; acquiring, with an image sensor, at least one first image of the removed reference optical lens; processing each acquired first image in order to deduce therefrom trimming parameters for the optical lens to be trimmed; and defining the trimming guideline as a function of the trimming parameters. Before or after the first acquiring step, a second step of acquiring a second image of the reference optical lens mounted in the spectacle frame, and in the processing step, the trimming parameters are defined as a function also of the second image is included.

A seamless lens cover, and methods of forming such a seamless lens cover. The cap structure that covers a camera of a rotating panoramic camera system includes a seamless lens cover through which images are obtained by the camera. The cap structure may be injection molded at an initial lens cover thickness, and then a portion of the as molded initial lens cover thickness may be removed (e.g., by machining away) to achieve the final desired thickness. By such a method, the lens cover may be injection molded at thicknesses suitable for injection molding (e.g., about 0.06 to about 0.1 inch), after which most of the thickness may be machined away, to provide a seamless lens cover having a thickness of less than about 0.015 inch, exhibiting at least 60% transmittance to the thermal spectrum, no lensing characteristics, and no curvature effect.
