Why is there a clear liquid on my eye classes from eye discharge?

See an eye MD: There are many causes for discharge from the eyes. Viral conjunctivitis (commonly called pink eye), a bacterial infection, underlying dryness, allergies, or a blocked tear duct could all caused discharge or tearing. See an ophthalmologist for a proper assessment and appropriate treatment.

Condensation?: Your eyes produce tear which is a clear liquid. When your lenses are pressed up close (leaning head on pillow/couch with glasses on?) to the eye, the vapor from your eye can condensate on the lenses and may appear a bit wet. This happens more often if you have watery eyes--when someone cries, his/her glasses often get foggy. Hope this explains your case.. Consult doc. Good luck.
