Eyelid swelling occurs when fluid or inflammation builds up in the tissues around one or both eyes. It may develop because of allergies, irritation, infection, injury, blocked eyelid glands, or other medical conditions. Eyelid swelling may be mild and temporary or severe enough to interfere with opening the eye.
Blepharitis is inflammation along the edges of the eyelids, usually near the eyelashes. It commonly causes red, swollen, itchy, or irritated eyelids and crusty or flaky material around the eyelashes. Blepharitis is not contagious and usually does not cause permanent eye damage, but it frequently returns and may require ongoing eyelid care.
There are two main types of blepharitis:

Blepharitis is a common eye condition that can affect people of all ages. It often occurs in both eyes and may continue for a long time or return after symptoms improve.
Eyelid swelling is also common and may occur with allergies, conjunctivitis, styes, blocked oil glands, skin conditions, injuries, or infections. Most mild cases improve after the underlying cause is treated.

Symptoms may affect one or both eyelids and may come and go.
Common symptoms may include:
Blepharitis may occur with dry eye, styes, chalazia, or inflammation of the eye surface.
A healthcare provider or eye-care professional will review your symptoms and examine your eyelids, eyelashes, and eyes. They may ask about:
Blepharitis is usually diagnosed through an eye examination. A magnifying instrument or slit lamp may be used to closely examine the eyelid margins and eye surface.

Eyelid swelling and blepharitis can have several possible causes.
Common causes include:
Blepharitis is often associated with bacterial buildup along the eyelid margin or dysfunction of the meibomian oil glands. Skin conditions such as rosacea and seborrheic dermatitis may also contribute.

Several factors may worsen eyelid irritation or cause symptoms to return.
Common factors include:
Contact lens wearers should remove their lenses and seek prompt eye care if swelling is accompanied by worsening pain, light sensitivity, discharge, or sudden blurred vision because contact lens-related corneal infections can threaten vision.

Not all eyelid swelling or blepharitis can be prevented, but healthy eye and eyelid habits may reduce the risk of flare-ups.
Helpful prevention tips include:

https://www.nei.nih.gov/eye-health-information/eye-conditions-and-diseases/blepharitis
Provides recommendations for controlling eyelid inflammation and reducing recurring symptoms.
Most cases of blepharitis or mild eyelid swelling do not require laboratory testing.
Laboratory tests may be considered when symptoms are severe, recurrent, unusual, or do not improve with treatment.
Possible tests may include:
A provider may collect material from the eyelid for testing when infection or excessive eyelash mites are suspected.
Laboratory Tests – NIH MedlinePlus

Provides information about common laboratory tests that may be used when infection, allergy, or another condition is suspected.
Most people do not require imaging or extensive testing.
Common diagnostic evaluations may include:

Provides information about eye examinations, eyelid disorders, and other eye conditions.
Treatment depends on the cause and severity of the eyelid swelling.
Treatment options may include:
Daily eyelid cleaning and warm compresses are often the main treatments for blepharitis. Prescription antibiotics or anti-inflammatory medications may be used when self-care is not enough.
Blepharitis Treatment – National Eye Institute
https://www.nei.nih.gov/eye-health-information/eye-conditions-and-diseases/blepharitis
Provides information about eyelid cleaning, medications, and managing recurring blepharitis.
Consistent eyelid care can help improve symptoms and reduce future flare-ups.
Helpful lifestyle changes include:
Blepharitis often requires regular eyelid care even after symptoms improve because it frequently returns.
Blepharitis – National Eye Institute (NEI)
https://www.nei.nih.gov/eye-health-information/eye-conditions-and-diseases/blepharitis
Provides practical instructions for managing blepharitis and maintaining eyelid hygiene.
Many cases improve without prescription medication.
Medications that may be recommended include:
Steroid-containing eye medications should not be used without supervision because they may worsen certain infections and can cause serious eye complications. Prescription treatment may include antibiotics, anti-inflammatory medication, or therapy for associated dry eye or skin disease.

Provides information about eyelid hygiene, antibiotic treatment, inflammation control, and long-term management.
Most people with eyelid swelling or blepharitis do not require invasive procedures. However, procedures may be recommended when glands remain blocked, complications develop, or symptoms do not improve with routine care.
Possible procedures may include:

Blepharitis is often a chronic or recurring condition. Symptoms may improve with treatment but return if eyelid hygiene is stopped or an underlying condition remains uncontrolled.
Most people can successfully manage blepharitis with regular warm compresses, eyelid cleaning, artificial tears, and prescribed medication when needed. The condition usually does not permanently damage vision.
Possible complications include:
Home care is an important part of treating blepharitis.
Helpful tips include:
Do not use water that is hot enough to burn the delicate eyelid skin.

No. Blepharitis is not considered contagious.
Yes. Redness and swelling along the eyelid margins are common symptoms.
Yes. Allergies commonly cause itching, watering, and swelling of both eyelids.
It is generally best to stop wearing contact lenses until redness, swelling, and irritation have resolved and your eye-care professional says it is safe to resume.
Symptoms may improve within days or weeks, but the condition frequently returns and may require ongoing eyelid care.
Blepharitis usually does not cause permanent vision loss, but severe inflammation can occasionally affect the cornea or cause temporary blurred vision.
Yes. Blocked and inflamed eyelid glands can contribute to recurring styes and chalazia.
Consider asking your healthcare provider:
Many cases can be managed by a primary care provider, optometrist, or ophthalmologist.
