(HealthDay News) - Dry eyes can be triggered by aging, eyestrain, exposure to sun, wind or smoke, or injury.

The U.S. National Library of Medicine offers these suggestions to help soothe dry eyes:

• Use artificial tears, or other moisturizing eye drops or ointments.
• Avoid smoking, and exposure to secondhand smoke.
• Avoid direct exposure to wind or air conditioning.
• Use a humidifier in your home, particularly during the dry winter months.
• Rest your eyes, and blink often.
