What Is Dry Eye?

Tears are essential for the eyes; if your eyes do not produce enough tears or tears are not evenly spread over the surface of the eyes, you can suffer from a condition known as Dry Eye Syndrome.

Dry eye syndrome appears when your eyes don’t produce the desired amount of tears or there is some problem with the tear film. When we blink, tear film spreads all over the eyes and keeps the surface smooth; tear film is quite crucial for good vision. For a complete understanding, it is better to understand its function.

The tear film comprises three layers; the oily layer, the watery layer and the mucus layer.

1. The Lipid Layer

This layer lies outside the tear film; its purpose is to keep the surface of tears smooth and avoids drying up tears unnecessarily. 

2. The Watery Layer

This layer lies in the central part of the tear film and significantly contributes to tear production. The watery layer serves the purpose of cleaning; it cleanses the eyes and removes undesired particles from the eyes. If any foreign particle/dust sticks to your eye surface, the aqueous layer washes it out from your eyes.

3. The Mucus Layer

The mucin layer is the innermost layer of the tear film; it stretches the watery layer all over the eyes’ surface and keeps it wet. In the absence of a mucus layer, tears cannot attach to the eyes.
