Here's why:
* Lacrimal Gland: Located above the outer corner of each eye, the lacrimal gland is responsible for producing tears. These tears are primarily composed of water, but also contain salts, mucus, and other components, creating a dilute saline solution.
* Function of Tears: Tears have several important functions:
* Lubrication: They keep the surface of the eye moist and lubricated, allowing the eyelids to move smoothly.
* Protection: They wash away dust, debris, and pathogens, protecting the eye from infection.
* Optical Clarity: They help maintain the smooth surface of the cornea, ensuring clear vision.
