Why is your eye dry?

Abstract

Dry eye syndrome, also known as dry eyes, is a common condition that occurs when the eyes don’t produce enough tears, or the quality of the tears is poor. Tears help lubricate and nourish the eyes. They also wash away foreign matter and keep the surface of the eyes smooth and clear. Without enough tears, the eyes can become dry, irritated, and inflamed. Dry eyes feel uncomfortable and may sting or burn and could even cause vision problems.
