摘要: An apparatus (3) for determining centering data for eyeglasses (2) comprises a fixation device (5) and a recording unit (4) that can be triggered by a computer, records electronic images, and is disposed behind a divider element (8). The fixation device (5) produces at least one speckle pattern. The speckles can be superposed by different patterns, for example, a cross shape. The invention further relates to a method for determining centering data. The inventive method and apparatus allow to measure for test persons having the most different acuity of vision the relative centering data from a short distance while maintaining their usual posture.
