Abstract
Provided is a head-mounted display that enables viewing of a stereoscopic image without visual fatigue caused by vergence-accommodation conflict. A head-mounted display includes a display device to display images for the left eye and the right eye on a screen, virtual image forming optical systems for the left eye and the right eye, respectively disposed with respect to images for the left eye and the right eye on the screen, and wide-focus lenses for the left eye and the right eye having a negative focal length with a range, and respectively disposed with respect to the virtual image forming optical systems for the left eye and the right eye so as to overlap optical axis directions of the virtual image forming optical systems for the left eye and the right eye. By respectively displaying virtual images of images, a permissible range of vergence and accommodation is expanded.
