EYE'S MOVEMENT AND ITS ANATOMY

There are roughly 130 million photoreceptors in the human eye, only in order of a million fibers in the optic nerve carry the signal to the brain. Eye movements are categorized in many different types of motion, two of which are most commonly studied: fixations and saccades. If the eye rests on a specific location for a certain amount of time, this non-movement is classified as a fixation. Fixations are those times when our eyes essentially stop scanning about the scene, holding the central foveal vision in place so that the visual system can take detailed information about what is being looked at. The movement from one fixation to the next is called a saccade. This is the fastest eye movement, in fact, the fastest movement the body can produce, with a duration between 30 to 50 milliseconds. Due to the fast movement during a saccade, the image on the retina is of poor quality and information intake thus happens mostly during the fixation period.
