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.
