An HMD device has an imaging optic for the right eye and an imaging optic for the left eye. Each imaging optic so images an image, which is generated in the object plane, that the image can be observed by a user in an image plane and each of the imaging optics includes an optical element ( 23 ) and a deflecting element ( 25 ) mounted downstream of the optical element ( 23 ). An image transducer ( 24 ) and the optical element ( 23 ), which follows the image transducer ( 24 ), are held by a linearly guided receptacle frame ( 15 ) moveable via a drive unit. A linear movement in the direction of an optical axis takes place. Adjusting wheels ( 4, 5 ) are mounted on respective sides of the image window for the right and left eyes. Each of the adjusting wheels ( 4, 5 ) is coupled mechanically to a corresponding cam curve. Each cam curve translates a rotational movement of the adjusting wheel ( 4, 5 ) into an output end linear movement of the receptacle frame ( 15 ).
