A method of processing an order request for an ophthalmic lens to be manufactured by a manufacturing device includes the following steps: receiving an order request including at least information related to an ophthalmic wearer's prescription by a first processing device; processing the order request by the first processing device on the basis of predetermined processing rules so as to obtain manufacturing parameters to be applied to the manufacturing device so as to manufacture the ophthalmic lens according to the information included in the order request; sending and storing the manufacturing parameters identified as requiring a further modification to a storing device and sending the other manufacturing parameters to the manufacturing device; modifying the stored manufacturing parameters by a second processing device and sending the modified manufacturing parameters to the manufacturing device.

Disclosed is a method for manufacturing an ophthalmic lens including a substrate and a functional film securely fastened to a curved face of the substrate. This method includes a method for gluing the initially flat functional film to the curved face. To ensure that the functional film when securely fastened to the curved face filters a preset band of wavelengths centered on a wavelength denoted λp, multiple functional films are preselected; two knowledge bases are established experimentally; a film is selected, using the two knowledge bases, from the plurality of preselected films, the wavelength λi′ on which is centered the band of wavelengths that this film filters for a certain degree of deformation being equal to λp when the degree of deformation is that given for the curvature in question; and the gluing method is implemented in order to securely fasten the selected film to the curved face.

A simulation system for simulating an appearance of a wearer's face wearing spectacles with accurate eye scaling includes a spherical component calculator that calculates a spherical component of a lens of the spectacles, the lens having an aspherical optical surface. The system further includes a simulation image generator that generates a simulation image of the wearer's face wearing the spectacles including accurately scaled eyes based on lens location information of the spectacles when worn and the spherical component. The system further includes a simulation image displaying unit that displays the simulation image. The lens location information includes a distance between a portion of an eye of the wearer and an eye-side surface of the lens.

A method of virtually trying on eyeglasses includes capturing a plurality of images of a user's face, obtaining locations of a plurality of feature points on the user's face in the plurality of images, and using the locations of the plurality of feature points in the plurality of images to create a standard three-dimensional model of the user. Next, a selection is received from the user of a pair of virtual eyeglasses, the selected pair of virtual eyeglasses having a corresponding three-dimensional model depicting the size and shape of the selected pair of virtual eyeglasses. After this, a modified three-dimensional model of the user having the selected pair of virtual eyeglasses superimposed on the user's face is created according to the standard three-dimensional model of the user and the corresponding three-dimensional model of the selected pair of virtual eyeglasses. The result is then displayed for the user to see.

A method of determining of user data for the production of an eyeglass lens for a selected eyeglass frame for a user. The method includes providing an eyeglass frame image data set of the selected eyeglass frame; gathering user image data at least of one portion of the user's head, together with at least one part of the selected eyeglass frame worn by the user; finding the pupils of the user in the user image data, and determining a pupil data set, said pupil data set comprising the size and/or the shape and/or the relative distance between the pupils of the user; and determining contour points of the rim of the eyeglass lens to be produced in the user image data, based on the eyeglass frame image data set and the pupil data set.

The invention relates to a device for determining the position of a characterizing point of an eye of a wearer provided with a spectacle frame (400), including: at least one image sensor apparatus (120); and positioning element for positioning the image sensor device relative to the spectacle frame (400), such that, when the spectacle frame is arranged in a useful position on the head of the wearer, the image sensor apparatus is capable of capturing an image of the eye of the wearer; and element for determining the position of a characterizing point of the eye from the at least one image of the eye of the wearer captured by the image sensor apparatus. The invention also relates to a method for determining the position of a characterizing point of an eye of a wearer, a device and a method for determining the direction of the gaze and a method for determining associated areas of wear of an ophthalmic lens.

Information is stored in an optical element in the form of a glass or plastic body embodied as spectacles lens, spectacles lens blank or spectacles lens semi-finished product. The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

A method for measuring at least one geo-morphometric parameter of an individual wearing glasses that includes adjusting the inclination of the image acquisition system so that it lies in an acceptable angular range; adjusting the height of the image acquisition system so that the individual can see the target along a substantially horizontal line of sight; observation of the target, by the individual; acquiring at least one image of the eyes of the individual and of the frame. The method includes processing the at least one image using the processing unit in order to determine each geo-morphometric parameter of the individual from the position of their pupils and the inclination of their glasses and returning the result of the measurements.

The invention concerns a method for measuring parameters necessary for producing corrective spectacles using an instrument (1) comprising the following steps: S1: positioning the wearer at a predefined distance from the frame (2) of the instrument (1), S2: placing a screen (5) of the instrument (1) opposite the wearer and displaying at least one image, S3: placing the frame of the corrective spectacles on the face of the wearer, S4: substituting the screen (5) with a one-way mirror (4) of the instrument, S5: taking the measurements.
