Are you using eye drops to help relieve your sore eyes? If you overuse eye drops that contain decongestants (ingredients that shrink swollen blood vessels) such as naphazoline, tetrahydrozoline, or phenylephrine, it could lead to conjunctivitis--swollen, red, sore eyes with a liquid discharge. It could take weeks for this condition to clear up. Use your eye drops as directed on the label, or your red eyes may actually worsen.
