System and method for gaze tracking at a distance

The present invention relates to a method and a system for tracking a gaze at a distance. The system for tracking a gaze at a distance according to one embodiment of the present invention comprises: an infrared lighting unit which includes a plurality of infrared lights emitting infrared light toward a user; a gaze tracking module which tracks the position of the user’s face and collects, from the tracked face position, an eye image including at least one reflected light among a plurality of corneal reflected lights caused by the emitted infrared light and a lens reflected light caused by spectacle lenses; a processor which compares the intensity of the lens reflected light in the collected eye image with a threshold and calculates a gaze position by detecting central coordinates of the corneal reflected lights if the intensity of the lens reflected light is less than or equal to the threshold.
