4. Dry Eye Syndrome
Dry eye syndrome is a disease that involves the surface of the eye. It is characterized by a loss of equilibrium among the components of the liquid layer (tear film) that bathes the outer layers of the eye (cornea and the conjunctiva). The mechanisms of dry eye syndrome are classically divided into aqueous deficient (inadequate tear production) and evaporative (increased tear film evaporation). However, many people can have a combination of these mechanisms. Furthermore, there are many potential causes that contribute to the development of this condition: systemic diseases, medications, surgeries, and ocular factors.
People with dry eye syndrome can experience a variety of symptoms which include a gritty sensation in the eyes, tearing, burning, pain, redness, and tired eyes. In addition, dry eye disease can cause monocular diplopia and blurry vision because the dryness makes the tear film uneven.
