"The second phase of the experiment is the eye transplant. Although this step seems simple, it is far from as easy as ordinary people imagine.
"Because it's not just about attaching the eye. We also need to ensure the optic nerve is successfully connected and functioning normally, which involves a very complex mechanism."
The female host, having delved into technical issues, instinctively paused and turned to look at the researcher.
The researcher promptly took over the explanation: "To understand this issue, first, we must grasp how humans see things. This process is not just related to the eyes but also involves the brain.
"Simply put, the essence of the eyes seeing things is that light enters the eyes, gets adjusted by the cornea and lens, and finally focuses on the retina.
"The retina comprises numerous visual cells, including cone cells and rod cells, which can convert light signals into neural signals, then transmit them to the brain via the optic nerve.
