A chalazion is a lump that develops when an oil gland in the eyelid becomes blocked.  It is usually painless and is not contagious. Your eyelids contain tiny oil glands called Meibomian glands. These glands produce oil that forms the outer layer of your tears and helps prevent tears from evaporating too quickly. When one of these glands becomes blocked: Oil cannot drain normally from the gland. The trapped oil accumulates inside the eyelid. The surrounding tissue develops inflammation. A firm lump gradually forms in the eyelid. A chalazion is often a type of chronic inflammatory reaction to trapped oil, rather than an active bacterial infection. Common Symptoms of Chalazion • A small lump on the eyelid• Eyelid swelling• Usually painless and not very red• Blurred vision if the lump becomes large  Chalazion vs. Stye Chalazion: Usually caused by a blocked oil gland and inflammation, a chalazion appears as a firm lump located deeper within the eyelid. It is typically painless or mildly tender. Stye (Hordeolum): Usually caused by a bacterial infection, a stye presents as a red, swollen, and often painful bump near the eyelashes or within the eyelid. It may develop a visible pus-filled point. Who is More Likely to Develop a Chalazion? Some people are more prone to blocked oil glands, especially those with: Blepharitis: Chronic inflammation along the eyelid margins. Meibomian gland dysfunction (MGD): Oil glands produce thick or poor-quality oil that does not flow easily. Rosacea: A skin condition that can also affect the eyelids and oil glands. Previous chalazia: A history of recurrent eyelid lumps. Seborrheic dermatitis: A skin condition associated with scaling and inflammation.
