Causes of Dry Eye

Dry eye can be temporary or chronic. The result of inflammation, meibomian gland dysfunction, decreased tear production, or increased tear evaporation – or a combination of these conditions.

Untreated dry eye can cause a variety of complications, including:

  • Eye infections

Dry eye is the result of inflammation, meibomian gland dysfunction, decreased tear production, or increased tear evaporation – or a combination of these conditions.

Cause of Dry Eye 

Surface Inflammation of The Eye

  • Prolonged screen time
  • Dry climates
  • Frequent and prolonged reading
  • Tear instability


Meibomian Gland Dysfunction

  • The blockage or other abnormality of the meibomian glands, impeding the secretion of oil into the tears.


Decreased Tear Production

  • Aging
  • Corneal nerve desensitivity caused by contact lens wear
  • Medical conditions such as Sjogren's syndrome, allergic eye disease, rheumatoid arthritis, and thyroid disorders
  • Medications such as hormone replacement therapy, anti-depressants, birth control, drugs for high blood pressure, and decongestants


Increased Tear Evaporation

  • Blepharitis
  • Blinking less often
  • Eyelid problems (ectropion / entropion)
  • Eye allergies
  • Preservatives in topical eyedrops
