Abstract
The invention discloses an optical module and a head-mounted display apparatus. The optical module includes a left/right lens barrel mechanism, a left/right sight distance adjusting mechanism, and a left/right pupillary distance adjusting mechanism; The left lens barrel mechanism includes a left lens barrel assembly and a left display screen disposed behind the left lens barrel assembly through a left screen bracket; The left sight distance adjusting mechanism adjusts the distance between the left display screen and the left lens barrel assembly; The left pupillary distance adjusting mechanism drives the left lens barrel mechanism to move left and right. Symmetrically, the structure of the right side is the same as left. The optical module adjusts the sight distance/pupillary distance of left and right eye separately by the left and right sight distance adjusting mechanism/pupillary distance adjusting mechanism, so that images seen by both eyes are clearer.
