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 or tetrahydrozoline, it could lead to conjunctivitis--swollen, red, itchy, sore eyes that may crust over at night from a liquid discharge. It could take weeks for this condition to clear up. Use eye drops as directed on the label or your red eyes may worsen.
