Fig. 1: Schematic of the main-sequence relation of saccadic eye movements and their instantaneous sensory consequences.
From: Lawful kinematics link eye movements to the limits of high-speed perception

a Peak velocity and duration of saccades increase lawfully with movement amplitude. b Saccades impose motion on the retina with kinematics that follow the same conjunction of amplitude, speed, and duration (illustrated for saccade amplitudes of 2, 4, 8, and 16 degrees of visual angle, dva).
