Tears are produced by glands above your eyes and drain through your tear ducts. Here's a breakdown:
Tears are essential for maintaining eye health and providing clear vision. The process of tear production is continuous, although it can increase due to various stimuli.
The Tear Production Process
| Step | Description | Location |
|---|---|---|
| 1. Production | Tears come from glands above your eyes. | Lacrimal glands |
| 2. Distribution | Every time you blink, a thin layer of tears called a “tear film” spreads across the surface of your cornea (the clear outer layer of the eye). | Cornea |
| 3. Drainage | Tears then drain into your tear ducts (small holes in the inner corners of your eyes) and down through your nose. | Tear ducts |
Types of Tears
While the basic process is the same, the type of tear being produced can vary. Tears can be categorized as:
- Basal Tears: These are produced continuously to lubricate and protect the eye.
- Reflex Tears: These are produced in response to irritation, such as dust or smoke.
- Emotional Tears: These are produced in response to strong emotions, such as sadness or joy.
Therefore, while your glands above your eyes constantly work to create tears, factors like blinking help distribute these tears, and your tear ducts manage the drainage.
