Document Summary
Movements that stabilize the eye when the head moves. Vestibulo-ocular: compensating for me moving, vestibular signal sensed in the inner ear. Movement in the environment puts a strain on the visual system. It has to deal with this issue, we need stable vision, not blurry. Movements that align the fovea with a visual target. Saccade: rapid eye movements from one target to another. Visual fixation: period between saccades when the eye is not moving, not moving when you have locked your eyes down so you can analyze what is coming off the retina. Saccade jumps to next word, visual fixation locks down to read it, saccade jumps. We have to be able to move the fovea around so we can see things with high acuity. Smooth pursuit: slower and smooth eye movement, want to follow some object moving in the environment. All of these are conjugate: the two eyes move in parrellel.
