    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.😊
