What causes tears in the eyes?

Our discussion is what causes tears in the eyes? Sometimes we all have tears in our eyes. They come out because of sorrow and because of happiness. Tears work to keep the eyes clean and hydrated.

Where do the tears come from?

Tears are shed through the lacrimal glands behind the upper eyelid. From this gland, new tears keep coming out and old tears also go to a tiny type of duct called lacrimal puncta. According to research, a person can produce 15 to 30 gallons of tears in a year. Tears of any kind usually contain water, lipids, lysozyme, glucose, and sodium.
