Why do our brains flip what we see?

Question

i’ve heard that because of the way light works, our eyes actually perceive images upside down and our brain works to correct this.

but why does our brain even do this? why not just make the flipped image the normal way we see? if we grow up with ‘upside down’ vision, wouldn’t we just adapt like those born with abnormal senses? shouldn’t leaving visuals undoctored just cut out some unnecessary work for our brain?

So your confusion comes because you are imagining, perhaps unwittingly, a place in the brain where everything “comes back together” after the photons are converted to nerve impulses in the eye. If that was the case then you would need to flip the image, like you imagine.
