Abstract

The invention relates to a magnifying vision aid for use as magnifying spectacles.
The magnifying spectacles in accordance with the invention have an automatic and/ or a manual focusing device, a device for manually altering the magnification factor and a device for automatic parallax compensation corresponding to the current focal lenath.

If, for instance during a vascular surgical operation, an alteration of the working distance is necessary due to the position of the different operation sites, the vision aid in accordance with the invention takes account of this requirement by the possibility of automatic or manual adaptation of the focal length and the automatic adaptation of the parallax angle. An optimum optical configuration, which always corresponds to the action which is being performed, can thus be ensured and a substantially less fatiguing operation than previously can be rendered possible by the selection of the most advantageous ergonomic position.
Furthermore, the vision aid in accordance with the invention offers the possibility of matching the magnification factor to requirements at every selected working distance.
