A tear is a watery fluid that trickles down from the eyes when certain emotions are triggered in humans and animals. Examples include happiness, sadness, pain, etc. Now to the types of tears there are.

Many people assume that all tears are the same, but that’s not true. There is more than one type of tear, and they are released under different circumstances.

The first type of tear is Basal tears. This type of tear happens when you blink, contains elements like water, mucin, lipids, lysozyme, lactoferrin, lipocalin, lacritin, immunoglobulin, glucose, urea, sodium, and potassium (proteins, salts and fats to help clean, lubricate and fight infection in the eye).

The second type of tear is called psychic tears. This type has an entirely different chemical make-up and contains hormones and natural pain killers. This type is usually visible during emotions like anger, happiness, etc.

Finally, there’s also the reflex tear. As the name implies, this type of tear comes spontaneously, especially if there’s a foreign body threatening the eye.

Don’t forget that it’s not necessary to wash your eyes. Your eyes do not require a wash. The tears produced in them sufficiently perform that task.
