A head mount display optical system according to one embodiment of the present invention comprises: a display unit for displaying an image; a first reflection module disposed in a propagation direction of image light of the display unit so as to reflect the light; and a second reflection module for reflecting the light reflected from the first reflection module in the direction of the eyes, wherein the first reflection module has a concave first reflection surface having a specific first focal length, and a first horizontal length, which is a horizontal length from the center of the first reflection module to the display unit, is shorter than the first focal length; a second reflection surface of the second reflection module is an inner surface of a glass lens; and the light provided from the display unit is reflected at the first reflection module and then reflected by the second reflection module so as to be provided to the eyes of a wearer. According to the present invention, the inner surface of the glass lens is used as a display screen so as to prevent a separate display unit from being exposed outward, such that the optical system is recognized as normal glasses by other people, thereby being conveniently wearable in daily life. |
