(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.
