Produce tears all the time, not just when we yawn or emotional experience. Healthy eyes are always covered with liquid, known as the tear film.
It is designed to remain stable between each blink. This is to prevent the eyes from becoming dry and allow clear vision.

If the tear glands produce fewer tears, the tear film may become unstable. It can break down quickly, creating dry spots on the surface of the eye.
Tears are made of water, fatty oils, proteins, electrolytes, substances against bacteria, and growth factors. The mixture helps keep the eye surface smooth and clear so that we could see well.
Dry eye can result from:
- Imbalances in the mix of tears, so it evaporates too quickly
- tear production is not enough for good eye health
Other causes include eyelid problems, some medications, and environmental factors.
Imbalance in a mixture of tears
The tear film has three layers, oil, water, and mucus. The problem with all of this can cause dry eye symptoms.
The top layer, oil, derived from the edge of the eyelid, where the meibomian glands produce lipids or fatty oils. Oil smoothes the tear surface and slows the rate of evaporation. incorrect oil level can cause the tears to evaporate too quickly.
