摘要： Methods and devices related to spectacle frame recommendation are provided. For configuring a device for frame recommendation, frame data is clustered into a plurality of frame data clusters, and head data is clustered into a plurality of head data clusters. A mapping between the head data clusters and the frame data clusters is performed. For recommendation of a frame to a person, head data of the person is obtained, and a head data cluster is identified based on the head data. Based on the identified head data cluster and the mapping, a frame data cluster is selected which forms the basis for the recommendation.

摘要： A method for tinting a spectacle lens substrate includes providing a spectacle lens substrate made from a polymeric lens material, providing a composition having a polymeric carrier material, applying a pattern of the composition on a surface of the spectacle lens substrate, and heating the spectacle lens substrate to allow for diffusion of a dye substance between the carrier material and the lens material. Moreover, a composition for in-substrate tinting of a polymeric spectacle lens substrate and a spectacle lens substrate having a polymeric lens material which exhibits a pattern of a composition having a polymeric carrier material applied on a surface of the spectacle lens substrate are presented.

摘要： A coating device for dip coating an ophthalmic lens is provided. The coating device includes a lacquer basin for receiving a lacquer mixture, which contains a lacquer and a solvent. The coating device has an overflow channel arranged at the lacquer basin for collecting the lacquer mixture overflowing from the lacquer basin, and a tubing system for providing an influx of the lacquer mixture to the lacquer basin, which is connected to the overflow channel for collecting a return flux of the lacquer mixture from the overflow channel to enable circulation of the lacquer mixture through the lacquer basin, the overflow channel, and the tubing system. The coating device includes a supply unit for dosing the lacquer and the solvent for the lacquer mixture, which is connected to the tubing system and configured to feed at least one of the lacquer and the solvent directly into the tubing system.

摘要： A method for applying a surface pattern on a surface of a spectacle lens substrate includes the following steps: providing a spectacle lens substrate having a polymeric lens material, providing a composition containing a swelling agent, applying a pattern of the composition on the surface of the spectacle lens substrate, and allowing for diffusion of the swelling agent from the composition into the lens material. Moreover, a spectacle lens substrate has a polymeric lens material and exhibits a surface pattern on a surface of the spectacle lens substrate. The polymeric lens material includes a swelling agent at positions forming the surface pattern, and a spectacle lens substrate contains a polymeric lens material, wherein the spectacle lens substrate exhibits a pattern of a composition containing a swelling agent applied on a surface of the spectacle lens substrate.

摘要： A method of producing a spectacle lens includes providing a substrate having a front surface and a back surface and coating or covering at least one of the front surface or the back surface of the substrate, in full or in part, with a layer. The surface topography of the substrate surface is changed by bringing the surface into contact with a medium and the medium is removed. A product made according to the method and including (i) a spectacle lens or (ii) a representation of the spectacle lens in the form of computer-readable data present on a data medium or (iii) a data medium including a virtual representation of the spectacle lens in the form of computer-readable data or (iv) a representation of the spectacle lens in the form of a computer-readable data signal, is also disclosed.

摘要： A computer-implemented method of generating data for calibrating optical coating apparatuses for applying optical coatings to surfaces of substrates is disclosed. The method includes measuring spectral data of a test coating applied by an optical coating apparatus at a first location; sending a coating data file containing the spectral data to a second location; comparing the measured spectral data of the test coating to target specification data for the test coating; and determining correction factors for correcting deviations to the target specification data for the optical coating apparatus based on the comparison between the measured spectral data and the target specification data; and receiving a target data file containing the correction factors at the first location and calibrating the optical coating apparatus by adjusting an operation parameter of the optical coating apparatus based on the correction factors to correct for deviations from the target specification data.

摘要： A testing device for detecting defects of transparent test specimens, in particular of ophthalmological lenses, has an illumination device for transilluminating test specimens to be examined and with an image acquisition device for imaging the test specimen transilluminated by the illumination device. The illumination device includes a plurality of linearly adjustable light sources for generating a stripe pattern. To capture the stripe pattern, the acquisition duration of the image acquisition device can be adjusted in such a way that the light emitted by each of the light sources is detected as a light stripe. Further, the disclosure relates to a testing method for detecting a defect of a transparent specimen.

摘要： Computer implemented methods for mobile device, mobile devices and computer programs are utilized for determining the center of rotation of the eye. An image of an eye of a person is captured in at least two positions of the mobile device, and the position of the center of rotation is determined based on the images and the position. In a similar manner, optionally a pupil position may be determined.
