Eye discharge refers to the sticky, yellowish and crusty substance that can sometimes make your eyes feel glued shut. It can be temporary such as when you wake up in the morning, or persistent in which case medical attention should be considered.
There are many causes of eye discharge, ranging from infections to allergic reactions. Most causes of eye discharge are not serious and can be easily treated.
People who are unwell (with cold or flu) may also have more eye discharge. Pollen, gusty winds, dry eyes or an eyelash can cause an irritation which may also lead to the discharge.
More serious causes of eye discharge may be infectious conjunctivitis and corneal ulcers. Both of these conditions can lead to further complications, so if you are experiencing pain, eye swelling or visual changes in addition to eye discharge, you should consult your eye doctor immediately.
