You Have More Than One Type of Tear (Tears Facts)
Tears are essential to help you see clearly and maintain the health of your eyes. They can also help communicate your emotions. Your body makes three types of tears.
Basal tears are in your eyes all the time to lubricate, nourish and protest your cornea. Basal tears act as a constant shield between the eye and the rest of the world, keeping dirt and debris away.
Reflex tears are formed when your eyes need to wash away harmful irritants, such as smoke, foreign bodies or onion fumes. your eyes release them in larger amounts than basal tears, and they may contain more antibodies to help fight bacteria.
Tears Have Layers (Tears Facts)
Tears are not just saline. They have a similar structure to saliva and contain enzymes, lipids, metabolites and electrolytes. Each tear has three layers. An inner mucus layer that keeps the whole tear fastened to the eye. A watery middle layer (the thickest layer) to keep the eye hydrated, repel bacteria and protect the cornea. An outer oily layer to keep the surface of the tear smooth for the eye to see through, and to prevent the other layers from evaporating.
How Your Body makes Tears (Tears Facts)
Lacrimal glands above each eye produce your tears. As you blink, tears spread across the surface of the eye. Then the tears drain into puncta, tiny holes in the corners of your upper and lower eyelids. Your tears then travel through small canals in the lids and down a duct before emptying into your nose. There, tears will either evaporate or be reabsorbed.
Tears from Baby eyes (Tears Facts)
Sometimes babies are born with a blocked tear duct, a condition that usually resolves on its own. An eye infection, swelling, injury or a tumor can cause a blocked tear duct in adults. When a lot of emotional or reflex tears are made, they overwhelm the lacrimal drainage system. That’s why these rears can spill out of your eyes, run down your cheeks and sometimes dribble out of your nose.
Even when you’re not crying, your body generates 1-2 microliters worth of tears. You don’t notice most of this production as they are blinked away as basal tears. Some of the tears are even rerouted down your throat while your body operates on autopilot.

Your nose runs up when you cry because excess tears come out of your nose. Each one of your eyes can only hold about 7 microliters of tears, and a strong crying session causes serious overflow. Those extra tears flood the nasal passages, which creates a runny and/or stuffy nose.
A neurological condition called Pathological Laughing & Crying (PLC) can cause involuntary crying at inappropriate times. The condition can be cause by ALS, Alzheimer’s disease, Multiple sclerosis, or a stroke.
Tiny Tears Size (Tears Facts)
The size of the tear disparity between genders is often cultural. Woman in wealthier Western cultures cry more frequently than woman in other countries. Simply put, excessive emotional crying is a first-world problem of sorts.
Tear ducts can also become blocked, causing complications. Blocked tear ducts can result from aging, injury, cyst, inflammation or a tumor. This can paradoxically cause excessive tearing and lead to infection of the affected eye.
