What is peripheral vision and how does it work?
In: Biology
Light hitting your eye from the side is directed into the eye and hits sensory cells just like light coming from in front of the eye, but It hits different ones in a different location due to the angle. Either the sensory cells aren’t as robust or numerous in that spot, or the brain just isn’t programmed to be able to see stuff clearly too far to the side. Either way, what the brain is very very good at is detecting changes in the image that is coming from the side. This gives us almost 6th Sense level motion detection, even in darkness that our forward vision can’t see very well in.
