Everything a person sees happened 15 seconds ago

[staarker]

The brain does not update a person’s vision in real-time. Scientists have found that we see only pictures that the eye recorded 15 seconds ago.

If we saw everything at once without delay, then it would seem to a person that he is hallucinating. Therefore, our brain “updates” the pictures gradually, with a slight delay.

The mechanism our brain uses is called the field of continuity. It allows us to feel stability in everything that happens around.

If the brain updated the pictures received by the organ of vision in real time, then the world would seem to a person an extremely restless place, where objects are constantly moving, shadows and light are changing. The effect would be comparable to a hallucination.
