If you suffer from dry eyes, especially at night, apply a thin layer of eye ointment underneath your lower eye lid. The ointment will keep your eyes moist throughout the night until morning. The ointment I use is over the counter and accessible for anyone to purchase. The product I use is called Systane Nighttime Lubricant Eye Ointment Overnight Relief. It is available over the counter for anyone to purchase. The price ranges from $10-$15, and the small tube does go a long way.
