eyes refer to a condition in the eyes when the tear produced by the tear glands isn’t able to provide proper lubrication to the eyes.
The tear gland might not be producing enough tears or the tears might be unstable, thus leading to damage of the surface of the eye.
Dry Eyes Symptoms, Causes, and Treatments – All About Vision
One can get dry eyes while riding a bike or after looking at a computer screen for several hours. When one has dry eyes, the eye starts to sting or burn as the eye’s surface is not lubricated well enough.

Causes of Dry Eyes
There can be multiple reasons for dry eyes. The eye’s tear glands consist of 3 layers:
- fatty oils
- vitreous aqueous fluid
- and mucus.
The combination of these layers keeps the eye surface clean and well lubricated, but a disruption in any of these layers leads to dry eyes. The reasons for disruption in any of these layers can be hormonal changes, autoimmune disease, inflamed eyelid glands, or allergic eye disease. Decreased tear production or increased tear evaporation can also lead to Dry Eyes.
- Keratoconjunctivitis Sicca is a medical condition when the tear production in the eye has reduces thus leading to lack of vitreous aqueous in the eye. It can occur due to ageing, Sjogren’s syndrome, allergic eye disease, Vitamin A deficiency, corneal nerve desentivity, nerve damage in eye surgery, etc.
- In some cases, the oil film in the eye may get clogged, this leads to tear evaporation and thus, dry eyes. Such disruption to the oil film can be caused by Posterior Blepharitis, eye allergy, exposure to wind, smoke, air, etc.
