PROBLEM TO BE SOLVED: To observe the direction or motions of the eyes of a patient under training by a doctor or the patient himself/herself. SOLUTION: The light reflected on the eye is passed through a half mirror 4, converged at an optical system 5 and made incident to a CCD 6 later and the image of the eye is formed. On the other hand, infrared light from an LED 7a of an illumination light generating part 7 controlled by an illumination light control part 10 is reflected on the cornea of the eye and similarly made incident to the CCD 6 and the image of the LED 7a is formed. The signal from the CCD 6 is supplied through a video input part 9 and an input processing part 11 to a providing image control part 8 and a video output part 15. Thus, the image of the eye and the image of the LED 7a are displayed on an LCD 2 controlled by the providing image control part 8, and the image of the eye and the image of the LED 7a are displayed on a display device connected to a video output part 15. |
