Blepharitis, meibomian gland dysfunction, and associated dry eye syndrome affect 30 million Americans. Due to this staggering amount of people that need help with eyelid disease, a flood of new products have come to the market in recent years.
Blepharitis is most likely due to an overgrowth of bacteria on your eyelids (naturally occuring bacteria), which create a discharge that looks like dandruff.
Symptoms of blepharitis include burning, oily, and crusty eyelids. You might also notice that in the morning your eyelids are stuck together.
