Eli5: the lens of your eye flips the image of what is happening in front of you and displays it on your retina, then your brain “flips” it again for you to perceive. What is the brain doing for that second flip?
It adapts your perception of the world into something more easily understandable. I was going to bring up the study where they inverted the image projected on the retina for a group of people (upside-down goggles), but someone already beat me to it.
