What causes the sty inside the eyelid?

Sties in the eyelids may be caused by poor eye hygiene, blepharitis, conjunctivitis and other reasons.

1, poor eye hygiene

If patients often do not wash their hands before wearing contact lenses, the bacteria in the hands may cause infection of the meibomian glands, causing styes.

2, blepharitis

If the patient has blepharitis, the pathogens may be transferred to the meibomian glands, and cause sterile infection of the meibomian glands, causing styes.

3, conjunctivitis

If the patient's conjunctiva is infected by bacteria, bacteria can multiply in the conjunctiva, may involve the meibomian glands, stimulate the meibomian glands to produce acute suppurative reaction, so that the patient has styes.
