Abstract: Apparatus for recording eye movement. A light source has its rays directed toward the eye of a subject and a glass dome secured to spectacle frames worn by the subject. The primary and secondary glints reflected off the glass dome and eye cornea, respectively, are transmitted via mirrors, lenses and a fiber optic image guide to a video camera tube. The position of the glints on an XY axis is electronically determined and the information is fed to a computer which compares the data from the two glints and compensates for the head movement which corresponds to movement of the primary glint.
