The sebaceous glands within the eyelid tarsal plates that release oil onto the surface of the eye are known as what?

Glands in the eyelid tarsal plates that secrete oil onto the eye surface are Meibomian glands. They produce meibum, a lipid-rich substance that forms the oily layer of the tear film. This oily layer coats the aqueous tears beneath, reducing evaporation and helping the tear film remain stable as you blink. That’s why these glands are essential for lubrication and comfort of the eye. The lacrimal gland makes the watery portion of tears, and glands around the eyelashes (such as Zeis or Moll) are associated with hair follicles rather than the tarsal plates, so they don’t fit the description.
