What causes a stye or a chalazion?

ANSWER

A stye usually stems from a bacterial infection that causes a blocked eyelid oil gland or clogged eyelash follicle. Stress and hormonal changes also can bring on a stye.

A chalazion happens when a tiny part of the eyelid called a meibomian gland becomes blocked.

Blepharitis, which is a condition that causes the eyelids to become inflamed, often is linked to styes and chalazia. So is rosacea, a skin condition.

Skin cancer also can cause styes and chalazia, though this is rare.

Also, a stye left untreated can sometimes turn into a chalazion.
