If it's still red after that many days, see a doctor. It could be anything from some small particle of something trapped under the eyelid irritating it, to an infection (i.e., pink eye), or you just rubbing it too much, or itching from allergies. A doctor can take a look and help find the reason and prescribe treatment if necessary.
