what gives us the ability to actually SEE things?
and could I implant it somewhere else in my body?

>> No.2414411

Eyes + brain = sight.

>> No.2414415

1. photosensitive cells and a lens
2. if you could implant a cloned eye, lay down some nerves and hook it up to the correct part of your brain, sure

Probably not in the next ten or twenty years, depending.

could we make a connection from our brain to somewhere else in our body artificially if we transplanted another eyeball from a different person?

Your eyes are just high resolution arrays of individual sensors that give a different signal to the brain when they are struck by varying wavelengths of light. They are nothing special.

It is your BRAIN that allows you to actually make sense of the storm of information your eyes give you. One artificial vision study I heard of a long time ago (but alas cannot recall the source) comes to mind wherein a camera was attached to a device that rested on a blind person's tongue. The device resting on the person's tongue would apply varying degrees of pressure on the person's tongue based on the intensity of light striking the individual pixels of the camera.

Put simply, imagine a grid of 10,000 pixels on the camera connected pixel-by-pixel to a grid of 10,000 tiny 'legs' pressed up against a person's tongue. Imagine, for example, that the more light a pixel gets, the more force it's associated 'leg' exerts on the person's tongue.

The results of this experiment showed that in a matter of weeks, formerly blind people were able to 'see' black and white images using the device.

Again, I recall hearing about this study from a long time ago, I don't have the sauce off the top of my head, but if you google "Artificial Vision" or similar topics I'm sure you can find it.

In short: Yes, OP. You can make an artificial eye, it doesn't have to be someone else's eye, it can be a camera. Yes OP, depending on how you arrange the sensors and haptic interface, your brain is generally sharp enough to 'figure out' how to interpret a signal if it needs to.

tl;dr Artificial eyes are not only possible, but have been done before. Google it.

Pic unrelated, because you don't need eyes where you're going.
