An eye is a lens. Lenses reverse the image. Think of a lens as a series of pinholes. A light ray from above goes through and ends up at the bottom. Left ends up right. etc. A lens is curved so the light going through the infinite number of pinholes focus at the same point.

It is a matter of basic physics; the human eye has a simple lens. If you take a simple lens (glass) and look through it, everything is focused upside down. Ergo, a simple lens makes things upside down (including the human eye). But our brain interprets things as being upside up. Now you know why toddlers have so much fun learning to walk; everything is upside down!

Our eyes are a single convex lens. If you were to take such a lens and project a picture through it, it would appear upside down and reversed on the surface behind it.
Similar with the eye and the retina has the projection upside down etc and the brain sorts it out and translates everything to proper orientation.

We know threw psychology that's how,because are brain is so complex that whenever we look at something it is upside down however, our brain reverses the image. Look in the mirror you'll see things backwards this is kind of how are minds works.

It is very simple. We have only one convex adjustable focal length lens in our each eye.It will give only reversed image at our retina a screen on our eye. You can see the cinema theater films it runs upside down only. Our brain only recognize it inverted position.

Scientists and Doctors do intensive research to figure out how the human eyes perceive things and how the brain interprets them.

The eye functions the same as replicatable lenses. Its taught in physics 2. If you remove an eyeball and shine a projector through it, the same would result.

by scientific observation of the eye, and its examination
it also has been shown to have over 2 million photographic cones
yet lol some athiests say it came by accident from a sun spot

Because the lens of our eye is a simple convex lens which produces an inverted image.

Is this a trick question? Because we can't literally know anything without the brain, or can we?
