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.
A swollen eyelid occurs when there is inflammation or excess fluid (edema) in the connective tissues surrounding the eye. Swollen eyes can be painful and non-painful, and affect both the upper and lower eyelids.
