Fact

We see everything upside down (and then our brains flip the image right side up for us).

The lens of the eye casts an upside down imagine onto our retina and then our brains take these two upside down images at slightly different perspectives (one per eye) and creates a single right-side up image.[1][2][3]

With that said, you probably won’t be surprised to hear that processing visual information takes a lot of our brains’ processing power.

FACT: We also see the world flat, but the two offset images we see and the light and shadowing allow us to perceive depth. So yeah, we see two upside down flat images that are slightly off from each other and the brain turns that into something useful. Very cool brain.

Conclusion

Arguments that the image we process is actually what we “see” aside, the images of the world cast on our retina are upside down and slightly off from each other and then our brains process the image for us. This allows us to see depth and to see the world as it is, right side up.
