Delusional eh? Hardly. Here's something you can try at home. You'll need a wall, a very bright torch (300 lumens should do), a poster with some writing on it and a helper. Hang the poster on the wall at eye level. Stand at a distance that you can comfortably read the poster. Read the poster. Now get your helper to turn the torch on and shine it away from the poster while holding it near the poster, and towards your line of sight. The helper shouldn't be obscuring the view of the poster with the torch itself. Read the poster again. You will find it less clear than before. You may even be unable to read it. This simple experiment will prove beyond doubt what I have stated. Good luck!
Don't know why but I hear the voice of hannibal lecter as I read that.
