A multitude of factors can impair the healthy tear film, resulting in dry eyes. Fatty oils, aqueous fluid, and mucus make up the three layers of your tear film. This mixture keeps your eyes moisturized, smooth, and clear in most cases. Dry eyes can be caused by issues with any of these layers.

Hormonal changes, autoimmune disease, irritated eyelid glands, and allergic eye disease are all possible causes of tear film malfunction. Dry eyes can be caused by low tear production or excessive tear absorption in some people.

When your body is unable to create enough water, dry eyes might develop. Keratoconjunctivitis sicca is the medical term for this condition. The following are a frequent causes of reduced tear production:

  • Aging
  • Health problems, such as Sjogren’s disease, reactive eye problem, rheumatoid arthritis, lupus, scleroderma, graft vs. host illness, sarcoidosis, thyroid disorders, or vitamin A insufficiency
  • Medications, including antihistamines, decongestants, hormone treatment, antidepressants, and pharmaceuticals for hypertension, acne, birth control, and Parkinson’s disease
  • Corneal nerve desensitivity, often caused by contact lenses, neuronal harm, or laser eye surgical intervention–though the signs of dry eyes associated with this condition are generally only temporary.

Small ducts on the border of your eyelids create an oil coating that can get stuck. Individuals with rosacea or even other skin conditions are more likely to have blocked meibomian ducts.

The following are likely reasons for excessive tear evaporation:

  • Blepharitis posterior
  • Blinking less frequently, which is common in certain illnesses like Parkinson’s disease, or while you’re focused on something like reading, driving, or working at a computer
  • Eyelid issues such as ectropion and entropion
  • Allergies to the eyes
  • Topical eye drops that contain preservatives
  • Wind, smoke, or a dry atmosphere
  • Deficiency in vitamin A
