A swollen eyelid can happen for many reasons. It can indicate an infection or other problem that requires medical attention. Treatment options depend on the cause.
Possible causes of swollen eyelids include:
- a stye or chalazion
- an allergy
- an infection, such as pink eye or blepharitis
- a health condition, such as Graves’ disease or liver failure
- a blocked tear duct
In this article, learn more about these and some other causes of a swollen eyelid, and get some tips on how to treat and prevent each cause.
The following pictures may help identify some causes of a swollen eyelid. Below is more information about some different causes.
A stye (hordeolum) is an infection of a gland in the eyelid. It is like a small abscess.
Symptoms affect the rim of the eye, often by the root of an eyelash.
A person may notice:
- a feeling of scratchiness
- a red bump like a pimple, usually with a small spot of pus in the middle
- crusting due to discharge
A stye often needs no treatment. It will usually resolve on its own in 1–2 weeks.
Here are some tips for managing at home:
- Apply warm compresses for 5–10 minutes, three to four times a day to relieve pain.
- Avoid eye products, including makeup and eye creams, until the stye disappears.
- Avoid wearing contact lenses until the stye goes.
- Use pain relief medication, if necessary, such as ibuprofen.
- Never pop a stye, as this can spread the infection and damage the eye.
A doctor may prescribe antibiotics.
It is not always possible to prevent a stye, but the following tips may help:
- Remove all makeup and wash the face before going to sleep.
- Avoid sharing personal items, such as towels, with someone who has a stye.
- Avoid rubbing or touching the eyes.
- If a person needs to put in contact lenses or touch their eyes, they should wash their hands first.
A chalazion forms a lump in the eyelid. It can look like a stye, but it is not an infection.
It happens when an oil gland in the eyelid gets clogged, and oil accumulates behind the blockage.
It feels like a hard lump. A person may also notice:
- swelling, which may affect a whole eyelid
- redness, in some cases
- a hard lump
- tenderness, in some cases
- blurry vision
A person may have more than one chalazion, known as chalazia, and the bumps can grow quite large. They usually resolve on their own after several days or weeks.
- applying warm compresses for 10–15 minutes three to five times a day to relieve discomfort and encourage the chalazion to drain
- using anti-inflammatory eye drops
- having steroid injections, in some cases
- minor surgery may be necessary to drain a chalazion
If the bump does not go away after a few days or there are other signs of an infection, such as a fever, a person should contact an eye doctor.
A person cannot always avoid chalazia, but they can try:
An allergic reaction to dust, pollen, and other common allergens can cause eye irritation and swelling.
- itching and burning
- watery eyes
- a stuffy or runny nose
Ways of managing symptoms include:
- applying cool compresses to relieve itching and swelling
- taking antihistamines, such as diphenhydramine (Benadryl)
- using over-the-counter (OTC) eye drops to reduce dryness and itchiness
- oral prescription medication and eye drops
The best way to prevent a reaction is to avoid exposure to known allergens.
People with a seasonal allergy can:
- monitor pollen counts
- wear glasses to prevent contact with pollen
- stay indoors, when possible, when pollen is high
- ask a doctor about allergy shots and other preventive medication
A person with a known allergy should carry an autoinjector in case of a severe reaction. Severe swelling and breathing problems may be signs of anaphylaxis, a life threatening condition that needs emergency medical care.
Anaphylaxis: Symptoms and what to do
Anaphylaxis is a severe allergic reaction that can be life threatening. The symptoms develop suddenly and include:
- swelling of the face or mouth
- fast, shallow breathing
- a fast heart rate
- clammy skin
- anxiety or confusion
- blue or white lips
- fainting or loss of consciousness
If someone has these symptoms:
- Check whether they are carrying an epinephrine pen. If they are, follow the instructions on the side of the pen to use it.
- Dial 911 or the number of the nearest emergency department.
- Lay the person down from a standing position. If they have vomited, turn them onto their side.
- Stay with them until the emergency services arrive.
Some people may need more than one epinephrine injection. If the symptoms do not improve in 5–15 minutes, or they come back, use a second pen if the person has one.
Applying a cold compress while sitting upright may help relieve symptoms.
The following tips may help prevent puffy eyes after sleeping:
- getting enough sleep
- sleeping with the head slightly raised
- limiting salt intake in the diet
- avoiding drinking liquids before sleeping

- following a varied diet with plenty of fruits and vegetables
- limiting salt intake
- having regular exercise
- seeking medical help if symptoms arise that could indicate a problem
- following a doctor’s advice on treatment
Crying can lead to puffiness around the eyes.
The eyes produce tears:
- to lubricate the cornea
- to wash away irritants, for example, dust or onion fumes
- in response to emotional triggers, such as joy or sadness
If the person produces a lot of tears, the lacrimal drainage system, which usually absorbs them, may be unable to cope. This can lead to puffiness.
A cool compress may help soothe discomfort after crying.
If a person finds they are crying more than usual or if crying or sadness is affecting their daily life, they may wish to seek medical advice.
Counseling can help manage depression, grief, anxiety, and other emotional factors that can lead to crying.
Makeup and skin care products can cause irritation, swelling, and puffiness in the eyelids for many reasons, for instance, if:
- they contain allergens or irritants

- products are not suitable for use around the eyes
- bacteria have developed over time, for example, on mascara
Artificial tears can help soothe discomfort if swelling occurs when using cosmetics.
A person should seek medical advice if symptoms continue or worsen.
To prevent inflammation due to cosmetics, a person should:
- take care to avoid contact between makeup and the eyes
- monitor for sensitivity reactions and introduce new products one at a time
- remove all makeup before sleeping
- choose good quality makeup that is fragrance-free
- replace all eye makeup every 3 months
- avoid sharing products with other people
Orbital cellulitis is a serious infection that occurs in the bony eye socket, known as the orbit. The most common cause is a bacterial infection of the nasal and sinus passages, or rhinosinusitis. But, it can result from surgery, an immune problem, and other causes.

- receiving highly active antiretroviral therapy, a treatment for some immune conditions
Quitting smoking may help reduce the risk.
There are many types of herpes virus, and some can cause infections in the eye. Ocular herpes simplex can lead to various eye infections with a range of symptoms.
These can affect the eyelids and other parts of the eye and include:
- irritation and redness
- inflammation of the cornea, the outer cover of the eye
- ulcers of the conjunctiva and cornea
- loss of sensation in the cornea
An initial infection often occurs in children under
A doctor will take an eye swab to check for the herpes virus.
They may prescribe:
- eyedrops containing antibiotics, steroids, or both
- intravenous medication, in some cases
- lubricating eye drops to help manage dry eye
- antiretroviral therapy to prevent recurrences and complications
- surgery, in some cases
The herpes simplex virus is very common, and infection is hard to prevent. Adults can help protect newborns by avoiding kissing them on the mouth.
Some people may need long-term antiretroviral drugs to manage the virus and help prevent a recurrence.
Blepharitis is an inflammation of the margins of the eyelids. It can result from a bacterial or viral infection or exposure to an allergen. Some people experience it only once, but it is usually a long-term condition in which symptoms improve and then flare up again.
Blepharitis can affect the eyelids in the following ways:
- ulceration, in some cases
- dandruff-like flakes around their eyelashes
- blurred vision
- feeling that something is in the eye

It is not always possible to avoid blepharitis.
- avoiding triggers that cause or worsen symptoms
- limiting the use of makeup
- regularly carrying out the hygiene steps above to prevent recurrence in people with chronic blepharitis
When a tear duct is blocked, the eye cannot fully drain tears. According to the American Academy of Ophthalmology, 20% of newborns have a blocked tear duct, but it usually resolves in 4–6 months. In adults, it may stem from an infection, tumor, injury, or other cause.
- inflammation, especially in the inner corner of the eye
- crusty eyelashes
- blurred vision
- traces of blood in tears
- a fever
- frequent infections
Often, a blocked duct will open without intervention.
For a newborn, a doctor may teach a caregiver how to do a special massage to encourage the duct to open.
If the duct does not open, a brief duct probing procedure may be necessary to restore drainage.
It is not possible to prevent a blocked tear duct. However, if symptoms worsen or there are signs of an infection, such as a fever, they should seek medical help.
Conjunctivitis, or pink eye, is an inflammation of the conjunctiva. This is the clear, thin tissue that lines the eyelid and eyeball.
Possible causes include:
