A system and method. The system may include an eye tracking system. The eye tracking system may include a short-wave infrared (SWIR) light source (302) configured to emit SWIR light at between 900 nanometers (nm) and 1,700 nm wavelength onto an environment, a SWIR sensitive image sensor (304) configured to capture images of the environment illuminated by the SWIR light source, and a processor (306) communicatively coupled to the SWIR sensitive image sensor. The processor may be configured to: receive image data from the SWIR sensitive image sensor; track movement of an eye of a user based on the image data; and output eye tracking system data indicative of the tracked movement of the eye of the user.
