Chalazion is a swelling in your eyelid caused by chronic inflammation of one of the small oil producing glands (meibomian glands) located in the upper and lower eyelids. This swelling is localized and often resembles a pea-like lump under your eyelid skin.hen a chalazion is small and without symptoms, it may disappear without treatment. If the chalazion is large, it may cause blurred vision by distorting the shape of your eye. A chalazion is sometimes confused with a stye, which also appears as a lump in the eyelid.
A chalazion is generally not an infection. A chalazion often starts out as a very small red, tender, swollen area of the eyelid. In a few days, it may change to a painless slow-growing lump the size of a pea. A chalazion is often confused with a stye (or hordeolum), which is an infection of an oil gland in the eyelid. A stye produces a red, swollen, painful lump on the edge or the inside of the eyelid and usually occurs closer to the surface of the eyelid than chalazia.
