Eye Movement



The visual system has evolved to perform exquisitely complex sensory, motor, and perceptual tasks.   It is able to focus on a range of objects in depth, track moving targets, attend to embedded figures, and perceive form in detailed contours.  Yet, it does so effortlessly and continuously in daily life.  This is due to the visual systemís organizational structure, which permits automatic performance of these complex tasks.  Understanding this structure requires more than qualitative or simple analytical approaches. Indeed, models are essential for assessing quantitatively its various components and their interactions.   Over the two and a half decades, our Vision Research Laboratory has performed numerous experiments and has developed various models to quantify and explain various human oculomotor behaviors.   The systems included:  accommodation (focusing), vergence (binocular eye rotations for viewing objects in depth), saccade (lateral eye rotations as in reading eye movements), and ocular growth pertaining to myopia (nearsightedness) development.
