The merger of tech and the human mechanism

As technology evolves,
It will start to merge more and more with our senses.
For instance, take the case of technology of the screen.
Its evolution moved from large CRT monitor screens to phone screens today.
Something even more intimate than phone screens is the AR or VR screen.
Even here there is a finer evolution happening.
Today we have VR headsets like the Oculus Rift which have 1080×1200 per eye.
But if you notice the mechanism of the eye,
The small area at the central portion of the field is the clearest and of highest resolution.
The rest of the peripheral part is at much lower resolution.
So, now they are working on VR headsets with 2 screens,
Where one screen is the high resolution background and the other is a tiny screen of much higher resolution that moves with the eye.
So this is an example of how the screen tech is slowly merging with the mechanism of our eyes itself.
The next step even beyond this logically would be to start to directly tap into the visual cortex in the brain itself.
Because the eye really is only a window that brings in information to the visual cortex.
If we could directly pass the information to the visual cortex, I would assume it would be indistinguishable from the real eye’s input.
In fact with directly passing input to the visual cortex, we could even have far more colorful rich and clear vision (like what is experienced on some psychedelics with the amplification of sensory circuits).
Technology would move merge into the senses, and then move into the brain circuits.
