If you have bad vision and you need to have font sizes enlarged, etc., to see the screen, then it should be a no-brainer that you should choose the standard resolution display.
If your vision is fine or your corrective lenses work correctly then the high resolution display would be an excellent choice. Consider choosing the antiglare model as well.
That said, no matter which display you choose, remember to always rest your eyes once in a while by looking outside or just stare off at something else in the room for a few minutes.
