Why does my eyes discharge a mucus like when u first wake up but they do it all day.

Eye discharge: If this is a short term problem, you may have infectious conjunctivitis (viral or bacterial). If this is a longer term problem, you likely have blepharitis or allergies. If you have itching as a symptom, it is most likely allergy. All of these are treatable, but you should be seen by ophthalmologist or optometrist for diagnosis and treatment.
