The eye is one of the most important organs in the human body, and it is important to protect the health of our eyes as we see the world and perceive light and color. Sometimes we find some dirt in our eyes, such as dust on eyelashes, eye droppings, etc., but strangely, some dirty things seem to disappear even though they don't feel rubbed out. So, all these dirty things that haven't been rubbed out of the eyes have gone? Let's unravel this mysterious mystery together.
First of all, the eye is a very amazing organ that has a self-cleaning function. The surface of the eye is covered with tears, which contain proteins, salts, and other components that can help wash the surface of the eye from foreign bodies and bacteria. When we blink or cry, tears will wash out the dirt in our eyes, which is one of the reasons why some dirt things that don't feel rubbed out eventually disappear.
Secondly, the dirt that is not rubbed out of the eye may be gradually expelled by the structure inside the eye. The surface of the eye contains a network of tiny capillaries and lacrimal glands, which help the eye to expel foreign bodies and keep the eye clean. Some dirt may be expelled with the movement of the eyeball or the movement of the blink, into the structures around the eye, such as under the conjunctiva on the inside of the eyelid. The conjunctiva is a smooth, moist layer of tissue that covers the surface of the eyeball and the inside of the eyelid, and it helps the eyeball to stay moist and expel foreign bodies. Some dirt may be absorbed or encapsulated by subconjunctival secretions, gradually expelling the eye.
In addition, dirt in the eyes can also be carried into the nasal passages by tears. Tears flow inside the eye and eventually pass through the nasolacrimal ducts in the nasal cavity to expel the dirt from the eye. This is also one of the reasons why the nose has a runny nose when crying.
In addition, some tiny dirt may dissolve inside the eye or be absorbed and processed by the eye's natural cleaning system. There is a special type of cell inside the eye, called scleral cells, that can engulf and break down foreign bodies, helping the eye to stay clean and healthy. As a result, some of the tiny dirt that is not rubbed out of the eye may be disposed of by these cells.
In general, dirt that is not rubbed out of the eye can be removed and treated in a variety of ways, including being washed away by tears, absorbed or expelled by structures around the eye, drained through the nasal cavity, and treated by cells inside the eye. The eyes themselves have powerful cleaning and health care functions, which can effectively deal with the dirt in the eyes and keep them clean and healthy.
However, despite these cleaning mechanisms, we should still take care to maintain eye hygiene and avoid allowing too much dirt to accumulate in our eyes. Washing your hands regularly, avoiding rubbing your eyes, and keeping the environment clean are all basic ways to protect your eyes. If you feel discomfort or a foreign body sensation in your eyes, you should rinse your eyes with water or seek medical help to avoid eye infections or other problems.
In our daily lives, we may pay little attention to the whereabouts of the dirt that is not rubbed out of our eyes, but they are processed and removed by the complex systems inside the eyes. It's all about protecting our eyes and allowing us to see this beautiful world clearly. So let's cherish our eyes and practice good hygiene so that they are always clean, healthy and bright.
The eyes are the windows of the soul, and to protect them is to take care of their souls. Let us explore and care for this amazing organ together, so that our eyes are always bright and clear, and we can see the beauty and tenderness of the world.
May our eyes always be as bright as ever and as pure as jade.
