Saccades are the fastest eye movements (up to about 500 degrees per second) and they are very brief in duration (typically less then 100 msec) [1].

How long does it take to make a saccadic eye movement?

The time course of a saccadic eye movement is shown in Figure 20.4. After the onset of a target for a saccade (in this example, the stimulus was the movement of an already fixated target), it takes about 200 ms for eye movement to begin.

How fast does an eyeball move?

We move our eyes three times a second, over 100,000 times each day.
