A chalazion is sometimes the aftereffect of a sty. It is less tender but lasts longer. Natural oils from the eyelid's oil glands must drain through ducts out to the eyelashes. If debris blocks this normal drainage, it may cause a sty or chalazion. Sometimes, this debris accumulates because of a condition called blepharitis, a long-standing inflammation of the edges of the eyelids, with redness, thickening and scales and crusts.
Chalazion facts. 1  A chalazionis a lump in the upper or lower eyelid caused by obstruction and inflammation of an oil gland of the eyelid. 2  A chalazion is not a tumor or growth and does not cause permanent changes in the vision.yelid glands are called the meibomian glands. They are also known as the palpebral glands, tarsal glands, or tarsoconjunctival glands. There are 30 to 40 of these glands in each of the upper and lower lids. These glands produce a thick liquid secretion that is discharged into the tear film of the eye.
