Hi, what you are describing sounds like what I am experiencing also right now, but in just my left eye. I also see a faint brown sport when I cover my right eye. Try covering one eye at a time, and look at different object in different lights, and see if anything seems different. Like the Dr.said you need to see a specialist and get checked out.
My diagnosis is fluid build up behind the retina. I thought maybe I was getting Macular Degeneration, and am glad I am not even if my problem is annoying, I am so glad I got to see a Dr. so soon. Good luck.
