A helmet mounted display system is described. A visor has an inner reflective surface and is mountable to head gear. A light source is arranged to emit light. Directing optics are arranged to image light from the light source onto the inner reflective surface of the visor to provide a reticle image on the inner reflective surface of the visor. An eye tracker is configured to determine the orientation of an eye of a wearer of the head gear. A controller is configured to receive an indication of the determined orientation of the eye, and to control the at least one actuator to change the orientation and shape of the directing optics to change the position of reticle image based on the indication of the determined orientation of the eye such that the eye views the reticle image.
