Dry Eye is more than an inconvenience. Dry Eye is a disease.
Many people suffer for years from the discomfort and pain of Dry Eye Disease Most try various products to manage their disease, and while many of the Over-The-Counter products can provide relief, it is just temporary symptom relief.
Meibomian Gland Dysfunction (MGD) is a leading cause of Dry Eye Disease.1 Dry Eye Disease is rarely due to a lack of the watery part of your tears. 86% of dry eye patients have MGD.2
What is Meibomian Gland Disfunction (MGD)?
Meibomian Gland Dysfunction is a progressive disease of the ocular surface. Long term, failure to treat MGD can lead to chronic discomfort and degradation of vision, significantly impacting quality of life.3
Healthy Meibomian glands that line your upper and lower eyelids secrete oil with every blink. Your Meibomian glands produce the oily part of the tear film needed to protect the surface of your eye by preventing the evaporation of the watery part of your tears. When this function is not working well, your eyes may feel dry. Keeping the function and structure of your Meibomian glands healthy before you become symptomatic is key, as MGD progresses over time.
What causes MGD?
MGD is caused by anatomical changes in the Meibomian glands If left untreated, MGD can become progressively worse over time.
