Swollen eyelid

Common causes of swollen eyelids

The delicate skin around the eyes is highly sensitive and prone to inflammation. A swollen eyelid can be caused by fluid retention or inflammation resulting from several factors.

Common causes include:

• Injury to the eye or surrounding area for example following a fall or blow to the eye in sport can cause bruising and swelling of the eyelids.

• Conjunctivitis, also known as "pink eye", affects the surface of the eye but can also cause inflamed and swollen eyelids.

• Eye allergies are caused when the body reacts to certain substances called allergens. These include things like dust, pet fur, pollen, certain eye drops or contact lens solutions, as well as some types of makeup.

• Styes are usually small, tender bumps on the edge of your eyelid, but they can also cause the whole eyelid to swell.

• A chalazion is a hard cyst that develops on the eyelid. It’s often confused with a stye and can cause the same type of tenderness and eyelid swelling.

• Blepharitis is a common eye condition that causes inflammation of the eyelids, resulting in redness and swollen eyelids.

How to treat swollen eyelids at home

Your GP or optician will be able to advise on the right kind of treatment for you, but there are a few things you can try at home if you think the swelling may be allergy‑related:

• Wash your face with clean water

• Use eye drops to clear the eyes and help calm down any itchiness

• Apply a cold compress, like a damp flannel, over your eyes to reduce irritation or swelling. This works by constricting blood vessels and reducing inflammation.
