I can't see straight and its COD4 Fault

I can't see straight I have officially played for 6 hours straight and Everything is all blurry. my hands are cramped and it was worth every minute of it. Can't wait to get home from work tomorrow. The game play is great the boards are awesome and the single player so far is perfect. What else can I say but Eat it to all who have to wait till Tue to play. LOL
