Origin: From saccade.
a sudden, violent check of a horse by drawing or twitching the reins on a sudden and with one pull
A saccade is a fast movement of an eye, head or other part of an animal's body or of a device. It can also be a fast shift in frequency of an emitted signal or other quick change. Saccades are quick, simultaneous movements of both eyes in the same direction. Initiated cortically by the frontal eye fields, 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.
