Swollen eyelid symptoms

A swollen eyelid can be a baffling symptom. It can be distressing to have such a sensitive part of your body as your eye suddenly seem to go wrong, especially when it is so visible to everyone. But swelling is actually part of the body's attempt to protect a part that may be injured, and when it occurs around the eyes it should always be investigated.

The most common causes of eyelid swelling are allergies. And the delicate structures of the eye are vulnerable to bacterial infections, which is why it's so important to wash your hands before touching or rubbing your eyes.

Injuries can cause swelling of one or both eyelids, either from direct trauma or due to blood and fluid being forced into the eyelid from an impact that occurs near it.

Common characteristics of a swollen eyelid

If you're experiencing a swollen eyelid, it can most likely be described by:

  • Puffiness of one or both eyelids: Usually the upper eyelids are affected, but it can be both upper and lower or just the lower
  • Red, hot, or discolored: The swelling may be red and hot, or the skin of the eyelid may be its normal color.
  • Bumpy: There may be small bumps along the inner rim of the eyelid.

Who is most often affected by swollen eyelid symptoms?

Hygiene is a factor with eye infections. Cleanliness of hands, face, washcloths, towels, and contact lenses is very important. Children are prone to eye infections since they don't always wash their hands as they should.

Are swollen eyelid symptoms serious?

The severity of a swollen eyelid is ultimately dependent on the cause.

  • Not serious: A swollen eyelid from an allergy or insect bite is not serious. The allergy can be treated, and the bite cared for so that it does not become infected.
  • Moderately serious: Bacterial infections of the rim of the eyelid are fairly common and can be treated with prescription drops from your medical provider.
  • Serious: Deeper infections anywhere around the eye, especially with redness, pain, and fever, should be treated right away before vision is affected.

Swollen eyelid causes

Most common swollen eyelid causes

The most common causes for a swollen eyelid include the following.

  • Allergies: Either seasonal allergies, food allergies, or something you touched just before touching your eyes
  • Bacterial infection of the conjunctiva: (the pink rim around the eyes)
  • Injuries: These can cause swelling and discoloration of the eyelids.
  • Insect bites: Usually from a mosquito, can cause one or more red swellings on the eyelid.

Less common swollen eyelid causes

Less common causes of a swollen eyelid include the following.

  • Bacterial infection at the base of an eyelash: Appearing as a small, sore bump with some swelling of the eyelid
  • Bacterial infection of the tiny oil glands around the eyelashes: Appearing as a small, hard lump that is usually not painful
  • Viral infections of the eyelid: These may appear as clusters of small bumps or scabs on and around the eyelids.
  • Infection following surgery or other treatment: This will appear as red, sore, and swollen eyelids.

Rare and unusual swollen eyelid causes

The following are far less common causes of a swollen eyelid, although possible.

  • Bacterial infection of the skin near the eye: It can begin as a sinus infection and then spread to the eye socket, causing redness and swelling of the deeper tissues around the eyes.
  • Skin cancer of the eyelids: This may first appear as a change in a mole.

This list does not constitute medical advice and may not accurately represent what you have.

Stye and chalazion

A stye (or hordeolum) is an infection in the upper or lower eyelid. There are three glands around the eye and one of them is infected.

You can treat this on your own with a topical antibiotic and warm compresses to help drain the infected area.

Rarity: Common

Top Symptoms: swelling of one eyelid, redness around the eye, feeling of something in the eye, eyelid lump, eyelid pain

Symptoms that always occur with stye and chalazion: swelling of one eyelid

Symptoms that never occur with stye and chalazion: fever

Urgency: Self-treatment

Periorbital cellulitis

Periorbital cellulitis is an infection of the eyelid or skin around the eye, which does not extend into the interior of the orbit (bony framework that surrounds the eyeball). Periorbital cellulitis commonly affects children under 18 months old.

You should seek immediate medical care at an urgent care clinic or ER. Antibiotics will be prescribed if bacterial infection is suspected, and immediate evaluation is recommended to make sure that the infection does not spread into the eye.

Rarity: Ultra rare

Top Symptoms: fever, eye pain, redness around the eye, swollen eyelid, swelling of one eyelid

Symptoms that always occur with periorbital cellulitis: redness around the eye

Symptoms that never occur with periorbital cellulitis: bulging of the eyes

Urgency: Hospital emergency room

Orbital cellulitis

Orbital cellulitis is a serious infection of the bony cavity (the orbit) which holds the eyeball. This condition affects the eye, eyelids, eyebrows, and cheeks, and causes the eyeball to have a swollen appearance. It can cause blindness if the infection is not treated.

You should seek immediate medical care at an urgent care clinic or ER. Antibiotics are given immediately to treat the infection, even before results from the laboratory have come back. You may likely be hospitalized as well.

Irritant contact dermatitis

Irritant contact dermatitis means a skin reaction that is caused by directly touching an irritating substance, and not by an infectious agent such as a bacteria or virus.

Common causes are soap, bleach, cleaning agents, chemicals, and even water. Almost any substance can cause it with prolonged exposure.

Contact dermatitis is not contagious.

Anyone who works with an irritating substance can contract the condition. Mechanics, beauticians, housekeepers, restaurant workers, and health care providers are all susceptible.

Symptoms include skin that feels swollen, stiff, and dry, and becomes cracked and blistered with painful open sores.

A medical provider can give the best advice on how to heal the skin and avoid further irritation. Self-treatment can make the problem worse if the wrong creams or ointments are used.

Diagnosis is made through patient history, to find out what substances the patient comes into contact with, and through physical examination of the damaged skin.

Treatment involves avoiding the irritating substance if possible. Otherwise, the person can use petroleum jelly on the hands underneath cotton and then rubber gloves.

Rarity: Common

Top Symptoms: rash with well-defined border, itchy rash, red or pink, rough patch of skin, painful rash, red rash

Symptoms that always occur with irritant contact dermatitis: rash with well-defined border

Symptoms that never occur with irritant contact dermatitis: fever, black-colored skin changes, brown-colored skin changes, blue-colored skin changes

Urgency: Self-treatment

Inflamed eyelid (blepharitis)

Inflamed eyelid, or blepharitis, is a bacterial infection of the skin at the base of the eyelashes.

If the oil glands around the eyelashes become clogged, normal skin bacteria will multiply in the oil and cause infection. The glands can become blocked due to dandruff of the scalp and eyebrows; allergies to eye makeup or contact lens solution; or eyelash mites or lice.

Symptoms include red, swollen, painful eyelids; oily, dandruff-like flakes of skin at the base of the eyelashes; and eyelashes that grow abnormally or fall out.

If the symptoms do not clear with hygiene, see a medical provider. Blepharitis can become chronic and lead to infections of the eyelids and cornea; dry eyes which cannot take contact lenses; and scarring and deformity of the eyelids.

Diagnosis is made through physical examination of the eyelids, under magnification and through skin swab of the eyelashes.

Treatment includes warm compresses and careful washing of the eyelids; antibiotics in pill or cream form; steroid eyedrops; and treatment for any underlying condition such as dandruff or rosacea.

Rarity: Common

Top Symptoms: eye itch, sensitivity to light, eye redness, feeling of something in the eye, dry eyes

Symptoms that never occur with inflamed eyelid (blepharitis): severe eye pain

Urgency: Self-treatment

Eczema (atopic dermatitis)

Atopic dermatitis, also called eczema, dermatitis, atopic eczema, or AD, is a chronic skin condition with an itchy rash.

AD is not contagious. It is caused by a genetic condition that affects the skin's ability to protect itself from bacteria and allergens.

AD is most often seen in infants and young children. Most susceptible are those with a family history of AD, asthma, or hay fever.

Infants will have a dry, scaly, itchy rash on the scalp, forehead, and cheeks. Older children will have the rash in the creases of elbows, knees, and buttocks.

Without treatment, a child may have trouble sleeping due to the intense itching. Constant scratching may cause skin infections and the skin may turn thickened and leathery.

Diagnosis is made through physical examination, patient history, and allergen skin tests.

AD cannot be cured, but can be controlled through prescribed medications, skin care, stress management, and treatment of food allergies. Those with AD often have allergies to milk, nuts, and shellfish. Keeping the skin clean and moisturized helps prevent flareups.


Angioedema is a condition which can cause swelling and puffiness of the face, mouth, tongue, hand or genitals. It is often related to an allergic reaction to food, medicines or insect bites.

Allergic reactions can be dangerous and therefore you should be brought to the nearest Emergency Room for evaluation and treatment. Call for an ambulance if you are experiencing any of the following symptoms: fainting, vomiting, trouble swallowing, tightness in throat or trouble breathing.

Acute allergic conjunctivitis

Itchy, red, swelling of the whites of the eyes can be caused by allergies to any number of things (like pollen, hay, etc).

Seek basic advice at a retail clinic, via telemedicine or at your primary care physician. Acute allergic conjunctivitis is usually treated by using artificial tears, cold compress, and/or an antihistamine (only if over 3 years of age). Additional tests might be ordered to look for the specific allergen. Try to avoid rubbing the eyes, this will only make the symptoms worse!

Rarity: Uncommon

Top Symptoms: eye itch, eye redness, watery eye discharge, itch in both eyes, eye redness

Symptoms that always occur with acute allergic conjunctivitis: eye itch, eye redness

Symptoms that never occur with acute allergic conjunctivitis: lump in front of the ear, vision changes

Urgency: Phone call or in-person visit

FAQs about swollen eyelid

Can allergies cause swollen eyelids?

Yes, allergies can cause swelling of the eyelids. This is often caused by the contact of allergens like dust, pollen, or pet dander within the eye, eyelid, or eyelashes. The swelling can be accompanied by itching, but is not usually painful. It often occurs in conjunction with a red eye (conjunctivitis) which may also be triggered by the same allergen. An over-the-counter allergy medication might help.

Why is my eyelid swollen in the morning?

Eyelid swelling is most commonly associated with normal, age-related changes to the blood flow in the eye as well as diet, salt consumption, amount of sleep, and circadian rhythm. If you eat a large amount of salt, your body can and will retain fluid. Sometimes this retention takes place in the hands, making it more difficult to squeeze one's hand, and other times it occurs in the eyelids, causing swelling.

Why is my eyelid swollen and drooping?

Your eyelid may be swollen because of an infection or blockage of an oil-secreting gland. This condition is called a chalazion. It usually looks like a red pimple-like area along the top or bottom of the eyelid. You may also have a more dangerous diagnosis, called orbital cellulitis, which can occur when an infection of the eye migrates into the eye socket. Pain, eyelid discoloration, and swelling along with fever, the eye bulging out or protruding, and difficulty moving the eye are common with this type of infection.

Are swollen eyelids contagious?

This depends on the cause. The most common causes of swollen eyelids are allergies and swelling related to allergies. If this is the cause of your eyelid swelling, it is not contagious. However, you may also have eyelid swelling caused by an infection, which can be contagious. Infections such as pink eye are very contagious, but do not commonly cause eyelid swelling.

Can the weather cause swollen eyelids?

Yes, weather or a change of seasons can trigger local allergic reactions (reactions in one part of the body), or systemic reactions throughout the body. If during pollen season you walk through an area with a heavy pollen burden, it may trigger eye swelling, eye congestion, or eye redness as well as a number of other allergic symptoms. At the same time, exposure to allergens that cause an allergic reaction throughout the body, like dust and pet dander, may also cause puffy eyes in the morning.
