what can cause eye goop
There are many causes of eye discharge, ranging from infections to allergic reactions to eye injury. Irritation of the eyes is a frequent cause of watery eye discharge. Allergic reactions can cause itchy, watery eyes. Both allergies and infections cause pinkeye, or conjunctivitis. Eye discharge associated with infections is usually accompanied by other symptoms including redness (bloodshot appearance), burning, blurred vision, or eye pain. Photophobia (sensitivity to light) can be associated with eye infections.
Some drainage or crusting of the lids, especially in the morning, may be normal. Clear or watery drainage from the eye is often due to allergies or a virus. The eyes may also be itchy and red and feel scratchy. Colds, flu, and viral pinkeye (conjunctivitis) also can cause watery eyes and a runny nose. It is very common for pinkeye drainage to cause the eyelids to stick together during sleep.
