A swollen eyelid is a very common symptom, and is usually due to allergy, inflammation, infection or injury. The skin of your eyelid is less than 1 mm thick but it is loose and stretchy, so your eyelid is capable of swelling quite dramatically. This leaflet discusses the reasons why your eyelids might swell, and directs you to more detailed leaflets explaining how to treat these various causes. Your eyelids are there to protect your eyes and to keep the surface of the eye particularly the cornea, which is the clear part of the eye over the iris and pupil from drying out. Each eyelid consists of thin skin with some pads of fatty tissue , muscle and a lid-shaped piece of thick fibrous material called the tarsal plate. These tarsal plates contain Meibomian glands which produce oily material which helps keep the eye and eyelid lubricated.

Eye discharge, or "sleep" in your eyes, is a combination of mucus, oil, skin cells and other debris that accumulates in the corner of your eye while you sleep. It can be wet and sticky or dry and crusty, depending on how much of the liquid in the discharge has evaporated. Other slang terms used to describe eye discharge include eye mattering, eye boogers , eye gunk, eye pus and goopy eyes. Sometimes called "rheum," eye discharge has a protective function, removing waste products and potentially harmful debris from the tear film and the front surface of your eyes. Your eyes produce mucus throughout the day, but a continuous thin film of tears bathes your eyes when you blink, flushing out the rheum before it hardens in your eyes.
