Watery eyes occur when the dry surface of the eye activates a protective mechanism by over-stimulating the production of the watery component of the tears. However, this cannot lubricate your eyes for long enough.

Causes Of Dry Eye Disease
To keep your eyes healthy and comfortable, there should be a consistent layer of adequate tears on the eye’s surface. This layer does not only keep your eyes moist but also prevent damage to the cornea by washing away debris, dust and microorganisms.
Following are important components of a tear film:
- An oily component
- A watery component
- A mucous-like component
The oily component increases lubrication by keeping the film from evaporating. Similarly, the two components also have respective purposes to serve.
- Meibomian glands present in the eyelids produce the oily component.
- Lacrimal glands produce the watery component.
- Goblet cells in the conjunctiva produce the mucous-like component.
Factors Increasing The Risk Of Dry Eye Syndrome
Following are the factors that can affect the production of the components of the film and cause dry eye syndrome:
- We blink our eyes less frequently and less fully while staring at a computer, smartphone or any other digital device. As a result, the risk of dry eye symptoms is high due to greater tear evaporation.
- Wearing contact lenses can also increase the risk of dry eye syndrome.
- The risk of dry eye syndrome is high after the age of 50.
- The risk is high in post-menopausal women.
- Forced air heating, ceiling fans and air conditioning systems often decrease indoor humidity and can cause dry eye symptoms.
- Dry or windy conditions and arid climates can also increase dry eye risks.
- As the air in airplanes is extremely dry, frequent flying can cause eye problems such as dry eyes.
- Smoking does not only causes dry eyes but various other serious eye problems as well such as uveitis, cataracts and macular degeneration.
- Sjogren’s syndrome, rheumatoid arthritis, lupus, thyroid-associated diseases and diabetes are some of the diseases that can contribute to dry eye.
- Birth control pills, certain blood pressure medications, antidepressants, and antihistamines are some of the prescription and nonprescription medicines that can increase the risk of this eye condition.
- Eyelids not closing completely while blinking or sleeping can also cause dry eye syndrome and other serious eye conditions.
