Understanding Tear Production and Drainage

Pernah bertanya-tanya apa lubang kecil di sudut kelopak mata Anda ini?

Sebenarnya, itulah alasan hidung Anda berair saat menangis.

Di atas sudut luar tiap mata terdapat kelenjar lakrimal,

pabrik kecil yang memompa cairan 24 jam sehari.

Setiap kali berkedip, kelopak mata Anda bertindak seperti wiper,

menyebarkan cairan itu ke seluruh kornea untuk membersihkan kotoran dan

menciptakan permukaan halus agar penglihatan jelas.

Dan itu bukan hanya air. Cairan itu penuh protein

dan senyawa pembunuh

bakteri yang melindungi mata Anda.

Namun, air mata itu harus mengalir ke suatu tempat.

Lubang-lubang kecil di sudut dalam itu disebut punktum lakrimal.

Lubang itu berfungsi seperti saluran pembuangan kecil, menarik air mata melalui saluran sempit

ke dalam kantung lakrimal, menuruni duktus nasolakrimal,

dan langsung ke rongga hidung Anda.

Itulah sebabnya hidungmu berair saat menangis, dan hanya ketika saluran pembuangan itu

benar-benar kewalahan, barulah air mata berlebih

akhirnya meluap melewati kelopak matamu.

Ever wondered what this tiny hole in the corner of your eyelid is? It's actually the reason your nose runs when you cry. Above the outer corner of each eye sits a lacrimal gland, a tiny factory that pumps out fluid twenty-four/seven. Every time you blink, your eyelid acts like a windshield wiper,

spreading that fluid across your cornea to wash away debris and create a smooth surface for clear vision. And it's not just water. It's packed with proteins and bacteria-killing compounds that shield your eyes.

But those tears need somewhere to go. Those tiny inner corner openings are called lacrimal puncta. They act like micro drains, pulling tears through narrow channels into the lacrimal sac, down the nasolacrimal duct, and straight into your nasal cavity.

That's why your nose runs when you cry, and only when those drains get completely overwhelmed do the excess tears finally spill over your eyelids.
