The most common type of dry eye, evaporative dry eye, is caused by a lipid (oil) deficiency resulting from a blockage of the meibomian glands.
Your tear film, made up of the lipids, aqueous, and mucin layers, is protected against evaporation by meibum, an oily substance found in the meibomian glands around the rims of your eyelids. When these glands are blocked or dysfunctional, your tears evaporate too quickly (between four and sixteen times faster than normal).
