An optical instrument, such as a microscope or a camera, is provided for forming a viewable image of an object. The optical instrument comprises an objective lens for forming the viewable image at an image plane, an eye sensor for sensing the direction of gaze of a user viewing the viewable image and means for controlling a controllable function of the optical instrument in dependence upon the sensed direction of gaze. The eye sensor comprises a sensor lens for focusing light reflected from the retina of the user, an imaging transducer located at a plane which is conjugate to the image plane with respect to the sensor lens, for generating an electrical image sign of a portion of the user's retina, a memory for storing retinal image information of the user and circuitry for comparing the retinal image signal generated by the imaging transducer with the stored retinal image information to generate gaze information indicative of the direction of gaze of the user.

1. A microscope for forming a viewable image of an object, comprising: an objective lens for forming a viewable image of the object at an image plane; an eye sensor for sensing a direction of gaze of a user viewing the viewable image; and means for adjusting a controllable function of said microscope in dependence upon the sensed direction of gaze; characterised in that said eye sensor comprises: (i) a sensor lens for focusing light reflected from the retina of the user; (ii) an imaging transducer located at a plane which when the user views said viewable image, is commonly conjugate with said image plane to the retina of the user's eye, for generating an electrical image signal of a portion of the user's retina; (iii) a memory for storing retinal image information of the user; and (iv) comparing means for comparing signals representative of the retinal image signal generated by said imaging transducer with said stored retinal image information to generate gaze information indicative of the direction of gaze of the user.
