1. A remote gaze tracking system, comprising:

  • an infrared lighting unit comprising a plurality of infrared lightings to emit an infrared light toward a user;

    a gaze tracking module to track a position of a face of the user, and to collect, from the tracked position of the face, an eye image comprising at least one reflected light among a plurality of corneal reflected lights and a lens-reflected light, the corneal reflected lights being reflected from a cornea by the emitted infrared light, and the lens-reflected light being reflected from a lens of glasses; and

    a processor to compare a magnitude of the lens-reflected light with a threshold in the collected eye image, and when the magnitude of the lens-reflected light is equal to or less than the threshold, to detect coordinates of a center of each of the plurality of corneal reflected lights, and to calculate a gaze position.
