1. A display apparatus comprising:
an image forming device configured to form a virtual image;
a vision correction lens configured to correct eyesight of a viewer;
a combiner configured to mix the virtual image with a real-world image in a surrounding environment that passes through the vision correction lens and provide the viewer with the virtual image and the real-world image that are mixed with each other; and
a virtual image positioner configured to adjust, according to a state of eyes of the viewer, a depth of a virtual image plane at which the virtual image is viewed,
wherein the combiner is arranged between the vision correction lens and the eyes of the viewer,
wherein the virtual image positioner comprises:
a focusing optical system arranged between the image forming device and the combiner;
a driving device configured to adjust a distance between the image forming device and the focusing optical system; and
a processor configured to control the driving device,
wherein the virtual image positioner is configured to adjust, according to the state of the eyes of the viewer, the depth of the virtual image plane at which the virtual image is viewed,
wherein the depth of the virtual image plane is determined based on a position of the image forming device with respect to the focusing optical system, and
wherein the processor is further configured to:
store information on a plurality of discontinuous positions, and
control the driving device to place the image forming device at one of the plurality of discontinuous positions according to the state of the eyes of the viewer.
