So one of the aspects of my science fiction world is genetic manipulation and modification of humans by one of the factions. I am wanting to have a subset of humans who receive a single eye transplant, or possibly both, for human eyeball sized mantis shrimp eyes to be used for combat. Also I acknowledge that currently eye transplants are not even possibly yet, but I assume that 200 years from now, the time of my story, that it will be possible to regenerate the optical nerves connecting the eyes and the brain.
Question 1: Is it possible to receive an eye transplant from another animal at all, or would the differences in cells, DNA, ect cause a horrible reaction?
Question 2: Assuming it was possible, would the eyes of the mantis shrimp, which see in 12-16 different spectrums, be able to be processed by the human brain? Would simpler eyes, like dogs which only see in blue and yellow, be able to be processed by the human brain?
