Described herein is a method (800) and system for controlling one or more illumination devices in an eye tracker system (100) such that a measured pupil/iris contrast exceeds a predefined minimum pupil/iris contrast. The method (100) includes: a. capturing images of a subject (102), including one or both of the subject's eyes, during predefined image capture periods; b. illuminating, from one or more illumination devices (108 and 110), one or both of the subject's eyes during the predefined image capture periods, wherein at least one illumination device (108 and 110) is located sufficiently close to a lens of the camera to generate bright pupil effects; and c. selectively varying the output power of at least one of the illumination devices (108 and 110) to generate a bright pupil reflection intensity such that a measured pupil/iris contrast in a captured image exceeds a predefined minimum pupil/iris contrast.
