What is a chalazion?
A chalazion is a swollen, painless lump on the eyelid.
The eyelid has tiny glands that produce oil to lubricate the eye. A chalazion occurs when these glands become blocked.
Initially, the lump is painful, but over time it no longer causes discomfort. It is common in people between the ages of 30 and 50 - it is rare in children.
Other symptoms may occur with a chalazion, including:
- Mild irritation;
- Blurred vision with a large chalazion;
- Swelling of the entire eyelid.
Chalazion is not contagious - it is not caused by a bacterial infection, so it cannot be spread from one person to another.
No one is immune to chalazion, but it is especially likely in the following cases:
- You have had a chalazion before;
- You have chronic inflammation of the eyelid;
- A history of any skin disease;
- Dry skin;
- Hormonal changes.
Keep in mind that if the chalazion is large, it may limit your vision.
