The function of tears.. Eye sterilization and disinfection because they contain sterile biodegradable materials UFOs and eye wash down

Definition of tears:

Eye tears, the clear liquid droplets formed by the lacrimal glands, can be defined in several ways, depending on the level of detail and scientific complexity desired:

Simple definition: Tears are a salty liquid secreted by the lacrimal glands located above the eyes. They bathe the surface of the eye, keeping it lubricated, protected, and clear for optimal vision.

More detailed definition: Tears are a complex mixture of water, electrolytes, proteins, lipids, and mucins. 

Functions of tears:

The functions of tears are indeed fascinating and go beyond just eye sterilization and disinfection, although that is one important aspect. Here's a breakdown of the various roles tears play:

- Eye lubrication and protection:

• Tears keep the cornea (the clear outer layer of the eye) moist and prevent dryness, which can cause irritation and damage.
• They wash away dust, debris, and foreign particles that enter the eye.
• Tears contain antimicrobial proteins called lysozymes that help fight off infections.

- Vision improvement:

• Tears smooth the surface of the cornea, allowing light to pass through more clearly for optimal vision.
• They help to focus light onto the retina at the back of the eye.

- Emotional expression:

• Tears can be a way of expressing emotions such as sadness, grief, joy, or pain.
• They can also serve as a social signal, fostering empathy and connection with others.

- Other functions:

• Tears may help to remove toxins from the body.
• They support the growth and development of the eye in infants.
• Tears may even play a role in lubrication during blinking, keeping the eyelids supple and healthy.
