摘要
Magnifying spectacles for surgical use have an automatic focusing device, a device for automatically altering the magnification factor and a device for automatic parallax compensation corresponding to the current focal length. During surgical operations, alteration of the working distance is commonly necessary due to the positions of different operating sites. Automatic adaptation of the focal length and the parallax angle allows optimum optical configuration to be reached without the need for the surgeon to use his hands. Focusing can be adjusted using a foot switch.
