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.
