The most common cause of eyelid swelling is eye allergies. Eye allergies sometimes cause significant discomfort, often interrupting daily activities with annoying symptoms such as eyelid irritation and swelling. Eye allergies develop when the immune system overreacts to a certain allergen.
Most often, eyelid edema is caused by allergic reactions to products such as eye makeup or eye drops, or allergens such as pollen. While most causes of eyelid edema are not dangerous, this condition can also be a symptom of trichinosis, a disease caused by eating undercooked meat, and other serious infections.
