What causes a chalazion?

ANSWER

A chalazion is a small lump or swelling in your eyelid. You have glands throughout your body, like tear and sweat glands. The meibomian glands in your upper and lower eyelids make oil that mixes with your tears to moisten and protect your eyes. If the oil gets too thick or if the glands are plugged because of inflammation, you may get a chalazion.

Sometimes an infection can cause a chalazion, though this is rare.
