Dry Eye Reasons
Many factors that disturb the normal tear film can lead to dry eyes. Three layers make up your tear film: mucus, aqueous fluid, and fatty oils. This mixture typically maintains your eyes’ surface moisturized, clear, and smooth. Dry eyes can result from issues with any one of these layers.
There are numerous causes of tear film failure, such as autoimmune diseases, hormonal fluctuations, irritated glands in the eyelids, or allergic eye conditions. Reduced tear production or increased tear evaporation can be the cause of dry eyes in certain people.
* Reduced tear production: When you don’t generate enough aqueous fluid, or liquid tears, you may have dry eyes. Keratoconjunctivitis sicca is the medical word for this condition, pronounced ker-uh-toe-kun-junk-tih-VY-tis SIK-uh. Typical reasons for reduced tear production are as follows:
* Growing Older: Certain illnesses, such as sarcoidosis, thyroid issues, lupus, rheumatoid arthritis, scleroderma, graft versus host disease, Sjogren’s syndrome, or vitamin A deficiency
A few medications, such as hormone replacement therapy, decongestants, antidepressants, antihistamines, and medications for high blood pressure, acne, birth control, and Parkinson’s disease.
* Corneal nerve desensitivity brought on by wearing contact lenses, injury to the nerves, or laser eye surgery, however the symptoms of dry eyes associated with this treatment are typically transient.

Why Does Dry Eye Occur?
Normally, tears are produced by glands above the eyes to keep the eyes moist. When your tears don’t accomplish their job, you get dry eyes. This could imply:
– Not enough tears are produced by your glands to keep your eyes moist.
– Your tears end up drying up too quickly.
– It’s like your tears don’t function well enough to keep your eyes moist.
How Do Tears Form?
Tears form a film over the eye when you blink. This maintains the cornea’s surface clear and smooth. For clear eyesight, the tear film is essential.
There are three levels to the tear film:
– Greasy coating.
– Moist layer.
– Coating of mucous.
– Every layer in the tear film has a specific function.
The outermost layer of the tear film is the greasy layer. In addition to preventing tears from drying out too rapidly, it smooths the tear surface. The meibomian glands in the eye produce this layer.
The tear film’s middle layer is the watery layer. Most of what we see as tears is composed of it. By removing foreign objects from the eye, this layer cleanses the lens. The lacrimal glands in the eyelids produce this layer.
The innermost layer of the tear film is called the mucus layer. This keeps the surface of the eye wet by distributing the watery layer over it. Tears would not adhere to the eye without mucus. From mucus, the conjunctiva produces it. This is the transparent tissue found inside your eyelids and covering the white of your eyes.
Normally, in order to stay wet, our eyes continuously produce tears. Tear production is increased when our eyes are inflamed or when we cry. However, occasionally the eyes fail to produce enough tears, or something messes with one or more tear film layers. In those situations, we get dry eyes.
