Eli5: Why does the human visual field seem to disappear when staring at something for an extended period of time without blinking the eyes?
In: Biology
This is called adaptation. The nerve cells respond best to changes, it’s the same kind of thing when you put a napkin or something light on your hand, you will feel it at first but then you get used to it.
Why do we have this evolved? Things that are moving and changing would probably kill us quicker than something that doesn’t. It makes sense that we are tuned to notice changes around us
