Health Tip: Causes of Dry Eye

(HealthDay News) -- Dry eye affects millions of adults in the United States, says the National Eye Institute.

In a healthy eye, tears keep the surface moist. Without this lubrication, people may feel a stinging, burning or scratchy sensation.

The institute mentions potential causes of dry eye:

  • Medications such as antihistamines, antidepressants and decongestants.
  • Conditions such as diabetes or rosacea.
  • Windy, smoky or dry environments.
  • Long periods of screen time.
  • Seasonal allergies.

People with symptoms should consult an eye-care professional.
