An eye-tracking method includes the step of removably affixing a ring member to an eye in surrounding relation to a cornea of the eye. A plurality of first light spots are transmitted onto the ring member, a second light spot is transmitted onto a reflective sector of the ring member, and reflections are detected from the first and the second light spots. By analyzing the reflections, translational and tilting eye movement can be detected. A system for tracking eye movement includes a ring member and a device for removably affixing the ring member to an eye in surrounding relation to a cornea of the eye, such as, for example, by applying a vacuum to the ring. The ring member can comprise concentric inner and outer rings having contrasting colors to each other and to the eye areas adjacent to which they are positionable.
