Causes of Swollen Right Eye

Allergic reaction: Allergic reactions can cause the body to release histamine, which can cause swelling and inflammation in the eyes. Common allergens that can cause this reaction include pollen, pet dander, and certain foods.

Infection: Bacterial or viral infections can cause swelling and redness in the eyes. Common infections that can cause this reaction include conjunctivitis (pink eye) and orbital cellulitis.

Injury: Injuries to the eye or surrounding area can cause swelling and bruising. These injuries can range from a simple bump or scratch to a more serious trauma, such as a fracture or contusion.

Sinusitis: Sinusitis is a condition that occurs when the sinuses become inflamed or infected. This inflammation can cause swelling and pressure around the eyes, which can result in swelling.

Thyroid disorders: Thyroid disorders can cause a wide range of symptoms, including swelling and inflammation around the eyes. This condition is known as thyroid eye disease or Graves’ ophthalmopathy.
