Abstract: A monitor is used to display a visual acuity test operated by software from an associated computer. A patient is spaced a predetermined distance from the monitor during the testing procedure, and individual, multiple LED housings are equally spaced about a center point of the monitor to direct light toward the patient during at least a portion of the test procedure.
