The present disclosure describes systems and methods for improving binocular vision, which generate a virtual image moving between two different depths to stimulate and then strengthen the weaker/abnormal eye of the viewer to eventually improve or even restore his/her binocular vision based on the viewer's eye information. The system comprises an eye tracking module and a virtual image module. The eye tracking module is configured to provide eye information of the viewer. The virtual image module configured to display a first virtual object by projecting multiple normal light signals to a viewer's first eye to form a normal image and corresponding multiple adjusted light signals to a viewers second eye to form an adjusted image.

Provided is a head-mounted display apparatus including: a display unit configured to display each of virtual screens that is set to each of a plurality of predetermined focal lengths; a distance-specific image generation unit configured to generate distance-specific display images for displaying, on the virtual screens, a display object representing an object to be displayed present between two focal lengths next to each other of the plurality of focal lengths; and a display controller configured to display each of the generated distance-specific display images on the virtual screen.

An augmented reality display device including a virtual image display and a controller is provided. The virtual image display is configured to provide a left eye virtual image and a right eye virtual image to a left eye and a right eye of a user, respectively. The controller is electrically connected to the virtual image display, and is configured to command the virtual image display to display a left eye virtual mark and a right eye virtual mark, corresponding to a real mark in space, in the left eye virtual image and the right eye virtual image, respectively, and calculate an interpupillary distance between the left eye and the right eye according to a deviation of the left eye virtual mark with respect to the real mark and a deviation of the right eye virtual mark with respect to the real mark.
