PURPOSE: A visual fixator is provided to fix the view angle of the eye of an examinee without causing eye strain, by permitting the eye of the examinee to correspond to the spot of laser beam even in case where the head of the examinee moves. CONSTITUTION: A visual fixator comprises a band type headset(10) constituted by a main body ring(11) and an upper ring(12) each of which has a length adjustable in accordance with the size of the head of an examinee; a portable power unit(40) fixed at the band type headset, and which supplies power to a laser beam emitter(20); a rod type switch(60) connected to a power cable(50) for interconnecting the portable power unit and the laser beam emitter, wherein the rod type switch controls on/off switching operation of the power cable; and an articulated holder(30) having a base(31) fixed on the band type headset, and an insertion portion(33) of a control shaft(32) to be coupled to the base in such a manner that the rotating angle of the articulated holder is movable in a limited range. The laser beam emitter is mounted on the control shaft of the articulated holder, in such a manner that the angle of the laser beam projected from the laser beam emitter is controllable.
