I feel very sorry about your problem. In general, red eyes are closely connected with swelling and dilated blood vessels which make the surface of the eye look red. Possible causes of red eyes vary from time to time. You just said that during sleep your eyes would become red. Perhaps this is due to lack of rest and sleep continuously. Or more seriously, I should say you probably have suffered from vernal conjunctivitis or more specifically epidemic hemorrhagic conjunctivitis. Epidemic hemorrhagic conjunctivitis is quite a serious eye disease which is infectious and widespread. So do not take your red eyes for granted and go to the eye doctor and have your eyes carefully examined to avoid more threatening problems in the following days.
