I have had a red eye for about five weeks now. There is no pain, itching, or other symptoms. In the morning when I wake up, it really doesn't look that red at all, but by the end of the day, it is bloodshot and it forms a red ring around most of my iris. The other part of the eye seems unaffected. At nighttime, I suppose I can feel a bit of strain, but that is about it. I also wear contacts, but I switched to new ones in case the old ones were the cause. Do I need to see a doctor, or will this eventually go away?
