Roy's fourth point is - rest your eyes occasionally by looking at something distant. Good advice - gotta get ya head out of that finder every now and then. I may have interpreted Roy's point all wrong, but the way I see it (oops!) an SLR viewfinder system is a self contained infinity scene, or it can be if you set up the diopter adjustment to be that way. That is, if you want to have relaxed eyes when looking through the viewfinder, then set the diopter so that the focussing screen image is at infinity for your eyes, or slightly beyond infinity for really relaxed eyes (just go to + 1 click of adjustment from where you eyes are relaxed). Diopter equipped SLR viewfinders and binoculars can be used to exercise one's eyes in this way, to counter staring at a computer screen all day. See, your Leicas are good for you.
