Abstract: Face protection equipment that comprises an eye imaging module for measuring an eye component (such as a retina, sclera, cornea, iris, limbus, pupil, or eyelid), can be used to measure an ocular parameter (such as saccades, vergence, smooth pursuit, gaze, eye fixation, pupil size, or eyeblinks). This ocular parameter measurement can then be used to assess human health, such as a traumatic brain injury. It can also be used to develop and implement ocular training protocols on a user-viewable display, and to assess the effects of a pharmacologic intervention.
