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.
Learn to recognize styes. Styes can be confused with chalazions, which also appear as a bump near the eye. The treatment of a stye and a chalazion is the same, so it's not a problem if you can't tell them apart. A stye or hordeolum is caused by bacterial infection. These red lumps are often filled with pus, like a pimple. Styes cause pain and swelling of the eyelid.
