The present invention is directed to an apparatus for the automatic adjustment of viewer settings in microscopes, particularly viewing height and viewing angle, interpupillary distance and/or dioptric compensation. In the apparatus according to the invention for the automatic adjustment of viewer settings in microscopes, the viewer settings with respect to viewing height and/or viewing angle and/or interpupillary distance and/or dioptric compensation can be automatically adjusted and/or predetermined, and these user-specific settings can be stored in a reproducible manner. The proposed solution is provided particularly for the automatic adjustment of viewer settings in microscopes regardless of the type of microscope. The solution according to the invention provides an apparatus for the automatic adjustment of viewer settings in microscopes by which the viewer settings can be adapted quickly and precisely to requirements, particularly to the requirements of different users. In this connection, the functionality of the microscope is improved, for example, by a constant regulation of a one-time preset ergonomic viewer setting, and the storage and reproduction of user-specific viewer settings are likewise improved.
