摘要： A device for determining centering parameters for the adjustment of spectacles includes a camera support partially surrounding an inner area that is open at the top, bottom and to the rear; and at least three cameras arranged between two free ends of the camera support and pointing towards the inner area, the camera support having an illumination system in order to illuminate the inner area. The illumination system is designed to light the inner area such that the light intensity, at least at each point in a region extending over a height of 20 cm and a central angle of 180 degrees of an outer cylinder surface having a diameter of 20 cm and formed in the inner area, deviates by a maximum +50% and −30% from a predefined desired value.

摘要： 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.
