1. An augmented reality system for use in a medical procedure, comprising:
a head mounted display comprising:
a camera configured to detect light from a target;
a near-eye display positioned between a wearer's eyes and the target, the near-eye display configured to display an image of the target based on the light detected by the camera, such that the image overlays a wearer's view of the target; and
a distance sensor, configured to determine a distance between the head mounted display and the target throughout a medical procedure; and
a processor, configured to:
determine a mismatch between the image of the target obtained from the camera and the wearer's view of the target based on the value of the distance measured by the distance sensor, and a position of the wearer's eyes;
adjust the position of the image on the near-eye display such that it is corrected based on the determined mismatch such that the image matches the wearer's view of the target; and
repeat the determination of the mismatch and the adjustment of the position of the image throughout the medical procedure to take into account changes in the distance measured by the distance sensor throughout the medical procedure.
