A chalazion, pronounced sha-LAY-zee-on, is a cyst-like bump in the upper or lower eyelid caused by inflammation due to a blocked oil gland. It may look a bit like a stye. While a stye involves a bacterial infection, a chalazion has no infectious element and may take much longer to resolve.
What is a Chalazion?
Meibomian glands, also known as tarsal glands, are located along the edge of the eyelids. They are an essential part of the eye, keeping it healthy and lubricated. They secrete fatty and oily meibum, and with every blink (with help from a tiny muscle called the Riolan's muscle), they spread a thin film over the tear film to slow the tear film's evaporation. Meibum also protects tears from spilling down to the cheek by trapping tears between the edge of the eyelid and the eyeball. It also makes the eyelid airtight when closed. Meibomian glands are located on both the upper (about 50 glands) and lower (about 25 glands) eyelids.
Glands of Zeis are also sebaceous (oil) glands that protect the surface of the eyelid, adding a protective layer to the top of the tear film. These glands secrete sebum to the middle section of the eyelash follicle, keeping it lubricated, and keeping the eyelashes from becoming brittle.
Glands of Moll are located at the base of the eyelashes. They are modified sweat glands, secreting sebum. However, unlike Zeis glands, these secretions contain immune system ingredients: the enzyme lysozyme, mucin 1, and immunoglobulin A, which suggest that they are part of the localized eyelid immune system. Their function is not precisely known, but they may be protecting against pathogens on the surface of the eye.1 Further research supports this hypothesis with the discovery of additional immune-system components.2
Chalazia usually, but not always, do not involve redness, soreness, and swelling. Twenty-five percent of chalazia show no symptoms other than the visible bump, and they usually disappear without treatment. But they can grow to a bothersome size and even blur vision, because they distort the shape of the eye.
- A hard nodule or swelling in the eyelid, typically a little farther from the edge than a stye, or sometimes on the underneath of the eyelid
- Red, swollen eyelid
- The skin outside of the chalazion usually isn't tender and can be moved around easily without pain.
- Blurry vision which could result if the swelling due to a chalazion on the upper lid is enough to press on the cornea.
Types of Chalazia
Chalazia can be categorized as either superficial or deep, depending on the glands that are blocked.
- Inflammation of a meibomian gland leads to a deep chalazion.
- Inflammation of a Zeis gland leads to a superficial chalazion.
As mentioned above, chalazia often disappear on their own. If recurring, or if the chalazia does not resolve, see an eye doctor, as in rare cases the chalazia may be cancerous. The eye doctor will drain the contents and review the test results, if needed.
Sometimes chalazia look like styes, becoming red, swollen, and tender. Other characteristics distinguish the two:
- Chalazia tend to develop farther from the edge of the eyelid than styes, grow more slowly, and are typically larger.
- Styes are smaller and more superficial than chalazia, usually look like a pimple, and have a small white dot in their center indicating an infection.
Who is at Risk?
- Those who get sties where the infection resolves but the white blood cells and fatty cell secretions don't completely drain and instead form a hard bump;
- suffer from rosacea with papules and pustules, especially around the eyes;
- suffer from blepharitis, or eyelid inflammation;
- have a meibomian gland dysfunction;
- have seborrhoeic dermatitis, a kind of eczema;
- are pregnant;
- or have adult-onset diabetes.
I just wanted you to know that I followed your protocol and my chalazion is 95% gone!! I’m very happy I could treat it naturally – and without surgery – and I very much appreciate your kindness and expert advice!
By the way, one of my co-workers told me he had them three times in a row – each time, he had it surgically removed, but then it came back. I told him that if it comes back a fourth time, he should speak to me first!

Chalazia take longer to heal than styes. In most cases they will resolve naturally in several weeks to months, but there are few things you can do:
- Diet and digestion. Diseases of the eyelid are often the result of a relationship between poor digestion and diet. In Chinese medicine problems of the upper eyelid often correspond to the spleen meridian and lower lid problems correspond to the stomach meridian. These imbalances can be prevented and improved by following diet and nutrition recommendations, including eliminating fried foods, eating plenty of fresh fruit, vegetables, whole grains, and using nutritional supplements. Acupuncture treatments may help as well.
- EyeEase is a soothing herbal formula for internal use and/or as part of a compress when irritation is present in the eyes. These are not eye drops, but herbs which have their primarily help to:
- Help the body to clear excess heat, congestion and inflammation from the eye area
- Combat bacterial and viral infections
- Clear the lymph and liver
- Stimulate and support the immune system
- Compress. Apply a warm, wet washcloth to the affected area and hold it in place until it cools, as you would when treating a stye. EyeEase can be used in the compress by adding one dropper to eight ounces of boiled water. The water should cool before using so the alcohol has a chance to evaporate, then dip the washcloth, squeeze out excess, and apply. Recommended application time is 5 minutes, 2-3 times per day for 1-2 weeks.
- Hygiene. Good eye hygiene is indicated, so use a baby shampoo on a cotton swab to wash the eye lids.
- Don't rub. Avoid rubbing the eyes, further irritating them.
- Don't squeeze. Never squeeze or try to pop the lump, as this will cause inflammation, infection or damage to the delicate tissues of the eyelid.
Beyond Self Help
Even though a lump in the eyelid is unappealing cosmetically, it is benign and will often resolve with the simple self-care instructions above. Please see your eye doctor if it does not resolve or becomes infected, if it is large enough to press on the cornea or if it becomes a persistent problem.
- Your doctor may prescribe a topical or oral antibiotic. Unless there is an infection present, this will not be effective.
- An eye doctor may drain the contents of the lump by making a small incision on the inside of the eyelid.
- The lesion can be injected with a corticosteroid to help drain it.
- If chalazia recur in the same location, the doctor may take a sample to test for tumorous growth.
