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?

You’re both right. The flipping is a consequence of your eye’s lens refracting the light and it being projected past the point where refraction hits its zero scale. The brain interprets this signal pretty directly, there aren’t neurons “flipping” anything, but your brain is interpreting an image where down is basically up.
