Question

रोने पर आँसू क्यों आत हैं।

Answer 1

We cry, or make tears, for three reasons. First, we need tears to keep our eye healthy, so you can say that our eyes cry a little bit all through the day. These types of tears usually don’t come out of our eyes.

Tears do come out of our eyes when we are emotional – either very sad or happy – or when our eyes are irritated by something, like a bit of dust that gets into our eyes or when we cut an onion.

Tears are needed for our eyes to work properly. Your eye has special parts – called glands – that make tears all day. Normally they only produce a tiny amount of tears – less than half a teaspoon per day. Tears are mostly water and a little bit of salt, but they also have some oil, mucus and chemicals called enzymes that kill germs.

A small amount of oil in tears stops them from evaporating or leaking out of our eyes. If we didn’t have oil in our tears, it would make our eyes really dry and sore.

When you blink, the eyelid spreads the tears around your eye and mucus helps the tears stick to the eyeball. Any tears left over drain through a special drainage system that goes through to your nose.

When we cry – and I hope you don’t cry too often – we make more tears than the eye can hold. This is because the largest tear gland can switch on and produce a lot of tears at once, just like a little fountain.
