A chalazion is an inflammation or blockage of the deep oil glands within the eyelid that develops into a small hard mass.
A chalazion first appears as a firm lump under the skin but is usually not painful.
Sometimes, a chalazion develops after a sty has healed.
On rare occasions, if a chalazion becomes quite big, it can press on the cornea.
If the chalazion is on the upper eye lid, it can produce various vision problems including astigmatism, a distortion of the lens that causes fuzzy vision.
If the bump is hard and is located deep within the eyelid, it probably is a chalazion.
Until the sty or chalazion is healed, the child should not wear contact lenses and the adolescent should not wear eye makeup.
Homeopathic practitioners prescribe oral homeopathic medications that reduce the bacterial growth within the sty and chalazion and thereby heal the inflammation.
