Methods and systems for using a polarization-sensitive camera to track changes in eye movement of a user are provided. The system may include a light source for directing light into an eye(s) of a user via a waveguide(s). The light reflected from the eye(s) may be captured by a polarization-sensitive camera configured to detect eye polarization phase change(s). The polarization-sensitive camera may utilize the polarization phase change(s) information to determine one or more eye polarization parameters. The eye polarization parameters may be utilized by a head mounted device of the system to determine eye tracking features associated with orientation and states of the eye(s), gaze direction of the eye(s) or segmentation of the eye(s).
