Abstract
A near eye display (NED) includes an electronic display configured to output image light. Further, the NED includes an eye tracking module and multiple optical elements that are combined to form an optical system to allow for changes in position of one or both eyes of a user of the NED. Various types of such optical elements, which may have optical states that are switchable, may be used to steer a light beam toward the user's eye. A direction of the steering may be based on eye tracking information measured by the eye tracking module.
