How will i know when my pink eye is gone?

Eyes less red: "pink eye" is the generic term for viral conjunctivitis. It runs a course of 5-10 days depending upon the virus. When your eyes become less red, then you probably are winning the battle and not shedding virus. When you have won the battle, the eyes turn white and stop dripping and irritation.

Red eye: Pink eye may be caused by a bacterium which responses to anti bacterial eye drops, whereas viral conjunctivitis doe not respond to eye drops unless it is specifically meant for a viral infection.
