How do we see?

The video explains that our eyes naturally see the world upside down. When light enters the eye through the pupil, it forms an inverted image on the retina. This image is sent via the optic nerve to the brain, which processes and flips it right side up, allowing us to perceive the world correctly. The video highlights the collaborative roles of the eyes and brain in vision.
