What Causes Dry Eyes?

Dry eyes are essentially caused by loss of tear production or tear evaporation, often caused by an imbalance of the tear mixture.

Tears are a delicate mixture of mucus, water and fatty oils that keep the eyes moist, fight infections and keep your eyes clear.

Common Causes of Decreased Tear Production

  • Tear Gland Damage
  • Age
  • Laser Eye Surgery
  • Some Medical Conditions (diabetes, lupus, rheumatoid arthritis, scleroderma, Sjogren’s syndrome, thyroid disorders and vitamin A deficiency)
  • Some Medications (acne drugs, antidepressants, antihistamines, birth control drugs, decongestants, high blood pressure drugs, hormone replacement and Parkinson’s disease drugs

Common Causes of Tear Evaporation

  • Eyelid Problems
  • Blinking Less
  • Dry Air
  • High Wind
  • Smoke

Why Should I Treat My Dry Eyes?

Those who experience dry eyes may experience the following medical issues.

Decreased Quality Of Life: Dry eyes make everyday living difficult. Simple tasks like reading or watching TV can become difficult and problematic.

Eye Infections: Tears help prevent the eyes from getting infected. A significant reduction or loss of tears can increase the chances of infection.

Eye Surface Damage: In addition to fighting infections, tears help protect the eyes from damage like abrasions, inflammation, corneal ulcers – all of which could impact vision.

Dry eyes can significantly impact your daily life and even lead to more serious medical conditions.

If you wear contacts, are a woman, over 50 or have a diet that is low in vitamin A, you’re also looking at an increased risk for dry eyes.

If you’re experiencing these symptoms, you should consult with a medical professional immediately to determine the most appropriate course of action.
