Abstract
A system for tracking eye movement is disclosed. A first light source, emitting light including a first wavelength, is adapted to illuminate corneal tissue of an eye. The first wavelength is selected such that it is strongly absorbed by corneal tissue. A position sensitive detector is adapted to detect a reflection of light at the first wavelength off the corneal tissue. Signal may be generated in response to the detected reflection which are representative of the position of the reflection, and therefore the position of the corneal tissue, with respect to the position sensitive detector.
