An eye-tracking method includes: acquiring an image of an eye of a user captured by an image-capturing module while the user is gazing at a gazing location on a screen module and a pair of light sources emit light toward the eye of the user determining an angle and an area based on positions of a pupil and two reflected light spots on the eye of the user, wherein the angle and the area correspond to the gazing location determining coordinates on the screen module based on the angle and the area, wherein the coordinates correspond to the gazing location and performing an operation associated with the coordinates. An eye-tracking system for implementing the eye-tracking method is also disclosed. A correcting method and a correcting module for the eye-tracking system are further disclosed.
