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.


  • Puffy appearance of one or both eyelids. Usually the upper eyelids are affected, but it can be both upper and lower or just the lower.
  • The swelling may be red and hot, or the skin of the eyelid may be its normal color.
  • 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?

  • 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.
  • Bacterial infections of the rim of the eyelid are fairly common and can be treated with prescription drops from your medical provider.
  • 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 cause types:

  • 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, which 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 cause types:

  • 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, which may appear as clusters of small bumps or scabs on and around the eyelids.
  • Infection following surgery or other treatment, which will appear as red, sore, and swollen eyelids.

Rare & unusual swollen eyelid cause types:

  • 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, which may first appear as a change in a mole.

FAQs About Swollen Eyelid

Here are some frequently asked questions 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.
