A swollen eye can be caused by a variety of factors, ranging from minor irritations to more serious health conditions. While it's often related to allergies, pink eye (conjunctivitis), or a stye, it's essential to consider other possibilities, especially if the swelling persists or worsens.
Common Causes of Swollen Eyes:
- Allergies: Contact with allergens like dust, pollen, or pet dander can cause your eyelids to swell, particularly in the morning.
- Pink Eye (Conjunctivitis): This infection can cause redness, itching, and swelling of the eyelids.
- Stye: A stye is a painful, red bump on the eyelid caused by a bacterial infection of the hair follicles.
- Blepharitis: This chronic inflammation of the eyelids can cause redness, swelling, and itching.
- Sleeping in Eye Makeup: Leaving makeup on overnight can irritate the delicate skin around the eyes, leading to swelling.
- Eye Injury: A direct blow to the eye can cause swelling and bruising.
- Insect Bites: Bites around the eye can cause local swelling and redness.
Less Common Causes of Swollen Eyes:
- Orbital Cellulitis: This serious bacterial infection of the tissues around the eye requires immediate medical attention.
- Chalazion: This non-cancerous lump on the eyelid is caused by a blocked oil gland.
- Thyroid Disease: Some thyroid conditions can cause swelling around the eyes.
- Kidney Disease: Kidney problems can sometimes lead to fluid retention, which can cause facial swelling, including around the eyes.
If your swollen eye is accompanied by other symptoms, such as vision changes, pain, or fever, it's essential to see a doctor right away.
Treatment for Swollen Eyes:
Treatment for swollen eyes depends on the underlying cause. For allergies, over-the-counter antihistamines or eye drops can help. Styes often resolve on their own, but warm compresses can help to speed up healing. Blepharitis requires regular eyelid hygiene to control inflammation. More serious conditions, like orbital cellulitis, will require antibiotics or other medical treatment.
