bloodshot eyes

I wonder if anyone can help me with this. About 2 yrs. ago we moved into a new house and I noticed that we (myself and my three kids, my husband seemed unaffected) got very tired, lethargic, and our eyes became bloodshot. Now, over the 2yr. period that we've lived here, the bloodshot eyes are still with us, esp. me! I also noticed that the white part of my eye is now sort of an off white, somewhat darker than it used to be (before we moved in here). It has stayed like that for these past 2 yrs. My skin color hasn't changed though. What can this be? SusanG Tweet
