Why do they put the eyes ‘back on’? I’m assuming they’re a reconstruction, but it anthropomorphosises them in the creepiest way
Take this with a huge grain of salt, but I remember hearing once that the eyes are kind of an external piece of the brain.
The Retina Wikipedia page seems to agree with you:
In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain, specifically the embryonic diencephalon; thus, the retina is considered part of the central nervous system (CNS) and is actually brain tissue.
Doing some further reading and there should be nerves present for all of our senses.
You can argue that this representation is what a human really looks like beneath our meatsuit. If you could keep it alive and gave it a mechanical body it not only contain all the same persons thoughts and feelings and with proficient adapters also full sense of senses.
