As a result of MGD (Meibomian Gland Dysfunction), the eyelids cannot produce the necessary quality or quantity of protective oils to keep the eyes healthy and moist.Without protective oils, the eyes become more susceptible to the negative effects that dry climates, air conditioning, computer us, reading and other daily activities can have on the long-term health of the eyes.In one study, 86% of patients with dry eye also had MGD. The good news is that MGD is treatable with LipiFlow.
