Document Summary
Smooth pursuit: a type of voluntary eye movement in which the eyes move smoothly to follow a moving object. Vergence: eye movements that occur when we rotate our eyes inward (converging) or outward (diverging) to focus on a near by object. Saccade: eye movement made either voluntary or involuntary, in which the eyes rapidly change fixation from one object or location to another. Reflexive eye movement: movement of the eye that is automatic and involuntary. Eg) when the eyes move to compensate for head and body movement while maintaining fixation on a particular target. Optokinetic nystagmus (okn): reflexive eye movement in which the eyes will involuntarily track a continually moving object. Reading the english language causes the perceptual span to be asymmetrical. Saccadic suppression: the reduction of visual sensitivity that occurs when we make saccadic eye movements. Saccadic suppression eliminates the smear from retinal image motion during eye movement.
