The automatic focus control apparatus and method in a wearable display system is disclosed. Focus automatic control device in wearable display apparatus according to an embodiment of the present invention, the distance to the lens corresponding to the wearable display device and the facial surface of a user wearing a wearable display system using a non-contact distance measuring device and a distance measuring section for measuring the distance between the lens and the panel; Lens position calculation unit calculating the position of the lens to maintain the focal length based on the difference between the distance and the reference value between the lens and the face surface of the user corresponding to the reference value; And based on the calculated value to move the lens and comprising a focusing distance maintained to keep the focus distance by adjusting the distance between the distance and the lens and the panel between the user and the lens.
