A method and system are provided for sensing eye motion, such as saccadic eye motion, in a non-intrusive fashion. An optical delivery arrangement (105) converts a laser beam pulse (104) into a plurality of light spots (21-24). The light spots are focused such that they are incident on a corresponding plurality of positions located on a boundary (12) whose motion is coincident with that of eye movement. The boundary can be defined by two visually adjoining surfaces having different coefficients of reflection. Energy is reflected from each of the positions located on the boundary receiving the light spots. An optical receiving arrangement (156) detects the reflected energy from each of the positions. Changes in reflected energy at one or more of the positions is indicative of eye motion.
