YOGYAKARTA - Why when our eyes are exposed to tears will come out? That is the question we can find in the book Natural and Social Sciences SD Class V.

The eyes are organs of the body that function as a sense of sight. Our vision can work well because of light.

However, the eyes often experience disturbances, for example being exposed to dirt. The reflectance that occurs in the eyes when exposed to dirt is removing tears.

Then, why when our eyes are exposed to feces will come out of tears? Check out the review below.

In the book Natural and Social Sciences SD Class V by Amalia Fitri Ghaniem, et al., tears come out after being exposed to dirt is a natural reflex where the eyes are trying to remove the dirt. If the dirt that enters the eyes contains more bacteria, the tears that come out will increase.

The liquid is useful for wetting the eye area and preventing bacterial exposure to the eye.

In addition, tears that come out are also due to enzymes called lysozymes. The enzyme is antimicrobial so that it can help clean the eyes and not be exposed to bacteria.

Tears are the glands produced by lacrymasi. The function of tears is cleaning and lubricating the eyes. Summarized from Healthline, there are several important facts about tears, including:

Tears have the same structure as saliva. The composition of partial tears is water, but there is also the content of fat oils, salts. Tears also contain more than 1,500 different proteins. In addition, in each drop of tears, there are also low levels of magnesium and calcium.

Tears consist of three different layers. The first layer is mukosa which keeps tears in the eye.

The second layer is aqueous, the thickest layer. The layer functions to hydrate the eyes, protect the cornea, and keep bacteria away.

Furthermore, there is an oily layer that prevents other layers from yawning. This layer also keeps the surface of the tears smooth so that humans can still see clearly.

It turns out that not all tears are the same. There are three types of tears, including:

Dry eye syndrome occurs when inadequate amounts or quality of tears lubricate the eyes properly. This syndrome occurs with symptoms of sore and itchy eyes.

However, some cases of dry eye syndrome actually make the eyes continue to run water. Watery eyes are a response to irritation.

The American Academy of Ophthalmology (AAO) explains that every year humans can produce about 15 to 30 gallons of tears.

Although many factors cause tear production to slow down, for example due to aging and health, humans will not actually run out of tears.

Humans will experience a decrease in the number of basal tear productions with age. This makes every parent experience dry eyes more often, especially in women who experience menopause.

Eyes and nasal channels are interconnected. When the lactrimal gland produces tears, tears will flow down through the tear tract which also leads to the nasal bone and to the back of the nose.

That's why when it comes out a lot of tears, our nose is also runny.

Eye irritation can also cause the lactural gland to produce tears. There are several causes of eye irritation, namely gas produced by onions, bright light, pungent smell (such as perfume), dust, chemicals, too long in front of the screen, and reading for a long time.

Tears are useful for keeping the surface of the eye smooth and clear and maintained from the risk of infection. So, when a person lacks tears, there is also a risk of experiencing some damage, such as abrasion of the cornea, ulcus, infection, and visual impairment.

In fact, there is still a lot of research on the impact of emitting emotional tears. However, some researchers have concluded that emotional tears have an impact on biological, social, and psychological factors.

Some researchers believe that crying is a social signal to receive help from others when they are in pain, sad, or feel extreme emotions.

A series of evidences conclude that emotional tears contain additional proteins and hormones that are not found in other types of tears.

Chances are, these hormones are pain relievers and help regulate the body to return to normal.

That's why a review of why when our eyes are exposed to dirt will come out of tears. Hopefully useful. Visit VOI.id to get other interesting information.
