    Why do some people have red eyes?

    I know that some medical condition can cause red eyes. But there are some people who always have red eyes. Is there any cause for that?

    Are you talking about bloodshot eyes?  A number of things can affect this; contacts, allergies, fatigue, or dryness.  A lot times just the environment like dust or humidity can effect eyes.  Some people are more sensitive to these things and it definitely can make your eyes "red."
