In the wonderful tissues of our body, there is an organ that has been silently hidden, but it is the window through which we perceive the world, and that is the eye. Why does this amazing organ exist on its own in our body and not be detected by our immune system? It's a fascinating question about the self-preservation mechanisms of the eye, the immune system's response to attack, and evolutionary mysteries.
The reason why the eyes are able to relax in our bodies is purely out of the need for self-preservation. Once detected by the immune system, the eye is exposed to a feverish attack by the immune system. The body and eyes employ two different immune systems, like two separate departments, isolated from each other to ensure each other's safety. The immune system is the guardian of our body, and whenever a virus invades, it takes a way to destroy the invader by raising its body temperature. However, the eye is very sensitive to heat, so it runs its own immune system to build a protective barrier for itself.
This independent immune system means that the eyes are hidden from our bodies all the time, and our immune system is unaware of their existence. And the reason why the immune system attacks the eyes so frantically is because the eye is neither a virus nor a bacterium for them, but a foreign body. This causes the body to react aggressively to the eye, and the white blood cells may quickly melt the eyeball into the eye socket, causing irreversible damage.
However, the mystery of the eye is not limited to self-preservation mechanisms. Its structural complexity is comparable to that of a sophisticated optical system, with pixels up to 57.6 billion, which is difficult for any digital camera to match. Even Darwin, who proposed the theory of evolution, repeatedly doubted whether the eye was a miracle created by God.
So, under what circumstances will the eyes be discovered by the body? The answer lies in an eye injury. When the eyeball ruptures and the lens proteins flow into the bloodstream as antigens, the immune system discovers the presence of the eye. The body produces antibodies that attack not only the injured eyeball, but also another healthy eyeball. Therefore, when one eye is injured, prompt surgical removal becomes essential so as not to damage the other healthy eyeball.
The mystery of the eye is amazing, and with its unique self-preservation mechanism and sophisticated structure, it has become a mysterious and safe area in the body. As we explore the mysteries of this tiny but indispensable organ, we can't help but be struck by the ingenuity of the human body's design. Perhaps, it is this mystery and complexity that makes the eye a unique window into the world. Among the many organs of the human body, the eye, with its unique existence and function, presents us with an incomparably wonderful picture of life.
