So this story, when our eyeballs move, there is a faint fast that happens when we turn away from one object to the next object. And it turns out, it is known that our brain does not have the ability to capture vague.
Furthermore, what is done by the vision system we are going to remove the faint of our memory and replace it with the next object we shall see. This is referred to as saccadic masking (saccadic disguises).
Still not clear? Let's do a little experiment. First, look at the analog (not digital clock ya, these experiments can only be done using a needle that has a clock time). Then, look at an object, anything, and quickly get your eyes in the direction of the clock.
There are weird? Take a look. When we look at the clock, the first movement of the second hand that we see will be felt much longer than the next movement. When eyes glanced quickly, the perception of time stretched slightly to the rear. Brain we note that we have looked at a little longer than the actual time. This illusion is known as clock-stopping illusion.
While this happens every time our eyes looking away from the fixation point to the next point, it is seldom we realize. The reason is a brain filled lag time when our eyes see objects move one object to the next.
