The eye is illuminated with infrared light, and the image of the eye is reflected to the helmet-mounted camera by an angled glass mounted in front of the wearer's eye. Some other hardware calculates and tracks the center of the wearer's pupil and a reflection off the cornea. For more info, contact: ISCAN 125 Cambridgepark Drive P.O.
