Are they disposable contacts? If not, it definitely sounds like you need a new pair. If they are, it sounds like you have (as the first response says) pink eye, or some other type of conjunctivitis. Go to the doctor (or eye doctor). Wear your glasses until its cleared up and then get new lenses... DO NOT wear the old ones anymore!
do you sleep with your contacts on
My hubby had the same thing it was pink eye, go to a dr., doesn't have to be red all the time, he wore contacts too~!
