The presently disclosed invention is a device for measuring horizontal and vertical eye movement. The device is adaptable to utilize multiple measurement technologies (e.g., direct infrared, electro-oculography, ultrasound, or video), and is capable of measuring each eye individually or both eyes jointly. The present invention overcomes the shortcomings of the prior art by requiring minimal adjustment for accurate measurement, only minimally obstructing the user's visual range (i.e., slightly more than the user's own nose), being made of low cost and readily available material, and by being comprised of a comfortable and efficient design of an adjustable nose and forehead piece with an adjustable head strap. An additional advancement over the prior art is that the presently disclosed device does not require an aperture or frame, as did the prior art, or any additional optics such as, lenses, mirrors, or prisms. The device rests on the user's nose with the sensors located near the nasal area of the eye(s) utilizing a nose bridge component to house the measuring technology. The forehead piece and head strap provide for ease of alignment, added stability, and a wide range of test applications. The greater field of vision provided by this device allows for a wide range of test applications.
