What Is a Chalazion? Symptoms, Causes and Everything You Need to Know

Chalazion vs Stye: What Is the Difference?

Because both conditions cause a lump on the eyelid, chalazia and styes are often mistaken for one another. However, they have different causes and can require different approaches to treatment.

A chalazion develops when one of the meibomian glands becomes blocked, causing oil to build up beneath the eyelid. It usually develops gradually over several days or weeks and is typically painless, although larger chalazia can cause discomfort or blurred vision by pressing against the eye.

A stye (hordeolum), on the other hand, is usually caused by a bacterial infection affecting an eyelash follicle or one of the eyelid glands. Styes often appear more suddenly and tend to be painful, red and swollen. In some cases, they may contain pus and eventually drain on their own.

Although the two conditions can look similar, an accurate diagnosis is important, particularly if the lump does not improve, continues to grow or keeps returning. An ophthalmologist can determine the underlying cause and recommend the most appropriate treatment.

Will a Chalazion Go Away on Its Own?

Yes, many chalazia resolve without surgery. Small chalazia often improve gradually with simple self-care, although this can take several weeks and, in some cases, even a few months.

The most commonly recommended home treatment is applying a warm compress to the affected eyelid several times a day. The warmth may help soften the blocked oil, allowing it to drain more easily. Gentle eyelid massage and good eyelid hygiene may also support the healing process.

While these measures are effective for many people, they do not work in every case. Some chalazia become larger, remain unchanged despite conservative treatment or continue to recur. If this happens, further assessment by an ophthalmologist is recommended to discuss other treatment options.

When Should You See an Ophthalmologist?

Although a chalazion is usually harmless, it is important to seek specialist advice if the lump does not improve with home treatment or continues to return.

You should consider seeing an ophthalmologist if:

• the chalazion persists for several weeks
• it continues to grow or becomes increasingly uncomfortable
• it affects your vision
• you experience recurrent chalazia
• you are unsure whether the lump is a chalazion or another eyelid condition

In rare cases, a persistent eyelid lump may resemble sebaceous gland carcinoma, an uncommon type of eyelid cancer. Although this is rare, an ophthalmologist can examine the eyelid and determine whether any further investigation is required.

FAQ

Is a Chalazion Painful?

Most chalazia are not painful. They usually develop gradually and feel like a firm lump beneath the eyelid. However, larger chalazia can become uncomfortable by pressing against the eye or interfering with normal eyelid movement. If the chalazion becomes infected, it may become red, swollen and painful.

Can a Chalazion Come Back?

Yes. Some people experience recurrent chalazia, particularly if they have underlying conditions such as blepharitis, rosacea or seborrhoeic dermatitis. Maintaining good eyelid hygiene and managing these conditions may help reduce the risk of future episodes.

Can Children Get Chalazia?

Yes. Although chalazia are more common in adults, they can also occur in children. Many resolve with conservative treatment, but persistent or recurrent chalazia should be assessed by an ophthalmologist to determine whether further treatment is needed.

Can I Wear Contact Lenses with a Chalazion?

It is generally recommended to avoid wearing contact lenses while you have an active chalazion, particularly if your eye feels irritated or inflamed. Wearing glasses until the eyelid has healed can help reduce discomfort and lower the risk of further irritation. If you are unsure when it is safe to wear your contact lenses again, ask your ophthalmologist for advice.
