Tears play an important role in the healthy maintenance of our eyes. Yes, they don’t just play a role in shedding emotions out but they have a scientific existence.

Tears are produced by lacrimal glands present at the base of the eyelids.

They are watery fluids composed of-

• electrolytes (such as sodium, potassium, calcium, magnesium, chloride, carbonates and bicarbonates)
• proteins and enzymes – the most important to be noted is lysozyme that protects the eyes from bacterial infections
• immunoglobulins such as IgA
• mucous – tears provide lubrication as well.

Thus, having all these compounds and proteins, specially the presence of electrolytes gives tears a salty taste.

I hope this answer helps.😊
