7 will work BUT as Der Vorsteher says it is tough to see detail on the split screen (I also need glasses but refuse to where them....). Mine came with it so I live with it. I would say if you can go large go large early! Go big or go home. Think of it this way, everyday you get older your eyes get worse......If I could afford a 52" screen I'd find a way to put in on there.
