WebSaccades are fast ballistic and preprogrammed movements that bring a target image to the fovea quickly; during a saccadic movement both eyes move in the same direction and with similar amplitude. WebSaccades are the fast movements used to change fixation rapidly. They are conjugate movements—that is, the eyes move equally and in the same direction. In laboratory conditions, after a step change in target position, the adult human central nervous system responds with a saccade after a latency of approximately 200 to 250 ms.
