In my opinion, yes. When your eyes focus the muscles in the back pull in or relax depending on what you are focused on. Sometimes when this happens you experience "shadows" which I think is just your eyes adjusting and pulling in the light as it focuses. Now, depending on when it occurs or how it occurs I might be completely wrong, but since I have experienced the same thing I typically push it aside saying, "It is just my eyes playing tricks on me".

I see sometime dark shadows out of the corners of my eyes. Are my eyes playing tricks with me?
