Swollen eyelids are common and can result from allergy, infection, or fluid build-up. The right response depends on the cause and associated symptoms.
Possible reasons for eyelid swelling
Mild puffiness may follow lack of sleep or high salt intake. More marked swelling with redness or pain can signal infection or inflammation that needs treatment.
- Allergic reactions causing itch, watering, and rapid swelling
- Styes or chalazia presenting as tender or firm eyelid bumps
- General fluid retention, especially noticeable on waking
- Skin conditions such as eczema affecting the lids
Safe first steps and when to seek help
Gentle care can ease mild swelling, but some situations require urgent review. Protecting the eye surface is always the priority.
- Use cool compresses for mild puffiness, avoiding direct ice on the skin
- Seek urgent care if swelling is severe, painful, or affects vision
- Do not squeeze eyelid lumps or share eye products
- Contact lens wearers should remove lenses until assessed
