Abstract: 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.

Abstract: 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′).

Abstract: Methods, devices, and computer programs for determining a near-vision point of a person are disclosed. The person under examination looks at a movable near-vision target, and an image of the person is captured with a camera device incorporated into the near-vision target. The orientation and/or position of the near-vision target is determined. The near-vision point is then determined from the orientation and/or position of the near-vision target.
