Did you know that every time you blink, the surface of your eyes are protected and moisturized by your tears?
Normally, your eyes produce healthy tears at a slow and constant rate. Tears keep the surface of your eyes moist so you feel comfortable. For people with dry eyes, the surface of the eyes does not get the moisture it needs.
What Is Dry Eye?
Dry eye occurs when the eyes either don’t produce normal tears or when tears are evaporating too quickly. It can lead to a sandy or scratchy sensation, and burning, itching or stinging eyes, among other symptoms.
