    摘要: This invention solves the problem that objects in the field of view of reading glasses using multifocal lenses for correcting ocular refractive errors such as presbyopia appear distorted. This image display device (3) is provided with the following: a distance computation unit (101') that computes the distance to a subject in a field-of-view image; a visual-acuity-information acquisition unit (103) that stores visual-acuity information for the user in advance; a corrected-image generation unit (105) that generates and outputs a corrected image on the basis of the field-of-view image and an eye image generated from the field-of-view image, the distance information, and the visual-acuity information; and a display unit (120) that displays the corrected image by superimposing same onto the user's field of view. Since the corrected image is superimposed without the use of lenses, lenses being the cause of the abovementioned distortion, the user can see close objects clearly.
