What is Lacrimation (tearing)?

Lacrimation is when your eyes make tears and let them out to keep them happy and healthy.

Tears are like little water helpers that clean your eyes and protect them from dryness or dirt. When something makes your eyes feel uncomfortable, like wind, dust, or even a funny face, your eyes start making more tears than usual, and they flow down your cheeks. That's why you might see someone crying when they’re happy or surprised.

Your eyes have special glands that act like tiny water factories. These factories make tears all day long, even when you're not crying. Usually, the tears just sit on your eye surface and help keep it wet and smooth. But sometimes, like when your eyes are really busy or tired, they let more tears escape, and that's what we call lacrimation.

Think of your eyes as a sponge in a pool. When the pool is full, the water just sits there. But if you squeeze the sponge too hard or splash it with something new, water spills out, that’s like tears coming out when your eyes are overworked or excited!
