Tear Drainage System
The lacrimal gland produces tears. These tears drain through two small openings called the upper and lower puncta, then through the canaliculus and into the lacrimal sac. They drop into the nasolacrimal duct and drain into the back of the nose and throat. Learn more about the tear drainage system at http://www.geteyesmart.org. -

The Three Layers of the Tear Film
Each time you blink, a tear film covers the eye to help you see. The tear film has three layers: an oily layer on the outside, a watery layer in the middle and mucous layer on the surface of the eye.

Punctal Plugs
Tears drain out of the eye through tiny openings of the tear ducts called puncta. If you have dry eye, your ophthalmologist may recommend closing off the puncta, either temporarily or permanently, using punctal plugs. Punctal plugs can save your own tears or make artificial tears last longer. Learn more at http://www.geteyesmart.org.
