Redness in eyes. This happening to me.

I have floaters and had adenoviral conjunctivitis one month ago. But recently I noticed redness in my eyes everytime I wake up, I thought it was lack of sleep, or cold or even infection. But this problem is even worse. I noticed the eyes becoming red every time I close my eyes, even when I'm no napping and just keeping them shut and awake, even if for a few minutes. But the redness does not stay at all, it clears out as soon as I open them, in fact within seconds its normal. But it is the same all over again after closing them. Throughout the day same thing. It started happening a couple days ago, and is continuing. I used to take antioxidant capsules gloeyes for floaters given by my doc, but have stopped them as well. But its not improving at all...what is this...why is this happening to me.
