<p>An eyestrain eliminator (1), comprising an image projection part (12) for projecting an image to a trained eye (10), a scanning mechanism (12d, 12e) for scanning the position of the image on the trained eye (10) basis in the direction of optical axis of the trained eye (10), and a control part (15) for controlling the scanning mechanism (12d, 12e), wherein the control part (15) allows the scanning mechanism (12d, 12e) to perform a training scanning for scanning the position of the image, acquires far point information indicating the far point of the trained eye (10) before the training scanning, and sets an image scanning range in the training scanning according to the far point information.</p> |
