A spectacle lens, which is manufactured by additive manufacturing, includes interspersing first volume elements and second volume elements. The first and second volume elements are arranged on the grid points of a geometric grid to form a first sub-grid and a second sub-grid, respectively. The first sub-grid forms the first part of the spectacle lens having a dioptric effect for vision for a first object distance and the second sub-grid forms the second part of the spectacle lens having a dioptric effect for vision for a second object distance, which differs from the first object distance.

Spectacle lens and method for producing a spectacle 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.

An apparatus and a method for measuring individual data of spectacles arranged in a measurement position are disclosed. The spectacles have a left and/or a right spectacle lens. The apparatus has a display for displaying a test structure. The apparatus contains an image capture device for capturing the test structure with an imaging beam path which passing through the left spectacle lens and/or the right spectacle lens of the spectacles. Further, the apparatus includes a computer unit with a computer program for determining a refractive power distribution for at least a section of the left spectacle lens and/or the right spectacle lens from the image of the test structure captured by the image capture device and a known spatial orientation of the display relative to the image capture device. To measure individual data of spectacles, the spectacles are arranged in a measurement position.

Measuring individual data of spectacles

A method for producing a spectacle lens by additive manufacturing includes interspersing first volume elements and second volume elements. The first and second volume elements are arranged on the grid points of a geometric grid to form a first sub-grid and a second sub-grid, respectively. The first sub-grid forms the first part of the spectacle lens having a dioptric effect for vision for a first object distance and the second sub-grid forms the second part of the spectacle lens having a dioptric effect for vision for a second object distance, which differs from the first object distance.

The spatial structure of an optical element is determined. The optical element has a first optically active surface and a second optically active surface. The optical element is arranged in a holding device. The position of a point (P) on the first optically active surface and the position of a point (P') on the second optically active surface are referenced in a coordinate system fixed to the holding device. The topography of the first optically active surface is determined in a coordinate system referenced to the holding device by the position of point (P) and the spatial structure of the optical element is calculated from the topography of the first optically active surface and from a data set as to the topography of the second optically active surface. The data set is referenced to the fixed coordinate system of the holding device by the position of point (P&#x2032;).

Method and system for determining the spatial structure of an object

A method and an apparatus serve for visualizing a signature mark on a spectacle lens. In order to identify the signature mark, an illumination light beam is directed onto the spectacle lens, which impinges on the spectacle lens, after impinging on the spectacle lens is reflected at a retroreflector, impinges once again on the spectacle lens, and finally is passed as an observation light beam to a camera. A reflection region of the illumination light beam on the reflector is varied by means of a moved first optical element.
