You make roughly three saccades per second. During each jump, your visual system suppresses the blur. The suppression begins before the saccade starts — a corollary discharge from the motor command that anticipates the movement. The world appears stable and continuous. Nothing of this is available for inspection.
Toggle between what you perceive and what a camera fixed to your eye would record. See also: Before the Jump.
The simulation runs at approximately real time. Each cycle — fixation, then suppression, then saccade — repeats at roughly three per second. The six dots represent fixation targets, like words on a line of text.
Raw input shows what a camera would record: the scene dims during the suppression window (before the eye moves), then smears across the frame during the saccade as the image sweeps across the retina at high speed.
Perceived view is what you experience: a stable, continuous scene with no gaps. The suppression window is invisible. The saccade generates no signal. From inside, nothing happened.
The suppression is not the same as the eye moving too fast to see. It precedes the motion. The brain sends the signal to go blind before it sends the signal to move. The order matters: if suppression were only a response to blur, you would notice the brief darkness. Instead, the darkness is never generated.
Objects shifted by up to half a degree during a saccade go undetected roughly 50% of the time. The default assumption upon landing is that nothing changed. What makes saccadic suppression different from ordinary inattention is that the inattention is mechanically produced and self-concealing: the process that would make the gap feel like a gap is suppressed while the gap occurs.
