I have to take a test where the paper has to be flat on the desk, but because I have bad eyesight and can’t wear glasses during the test, I have to get my face relatively close to the paper. The only issue is that when I do that, my head feels much heavier (like it would if I were hanging upside down but not nearly as severe) and mind feels clogged. Hopefully this is psychogenic. Besides the psychological discomfort, would I be at a disadvantage compared to other students who are able to see with much more normal posture? I’m hoping that it’s something that would go away with practice being in that posture.         

Also, if there are any effects: I’ve been using my phone flat on the table which has much smaller text than printed pages, so maybe I won’t have to get as close during the real thing?
