Wikipedia

  1. Saccade

    A saccade ( sə-KAHD, French for jerk) is a quick, simultaneous movement of both eyes between two or more phases of fixation in the same direction. In contrast, in smooth pursuit movements, the eyes move smoothly instead of in jumps. The phenomenon can be associated with a shift in frequency of an emitted signal or a movement of a body part or device. Controlled cortically by the frontal eye fields (FEF), or subcortically by the superior colliculus, saccades serve as a mechanism for fixation, rapid eye movement, and the fast phase of optokinetic nystagmus. The word appears to have been coined in the 1880s by French ophthalmologist Émile Javal, who used a mirror on one side of a page to observe eye movement in silent reading, and found that it involves a succession of discontinuous individual movements.

    A saccade is a rapid, jerky movement of the eye as it jumps from one point to another, usually while quickly scanning a scene. These movements are unconscious and are thought to be the fastest movements produced by the human body. They occur when the gaze shifts, such as while reading or looking around.
