Dry eye is a very common disease, with a prevalence of up to 75% in some groups. Left untreated, dry eye can progress and significantly affect your daily life.  Meibomian gland disease (MGD) is the most common form of dry eye and has been shown to affect 86% of patients with dry eyes.

Dry eyes feel uncomfortable. If you have dry eyes, your eyes may sting or burn. You may experience dry eyes in certain situations, such as on an airplane, in an air-conditioned room, while riding a bike, or after looking at a computer screen (or smartphone screen) for too long.
