The outdated advice was that the text you were looking at most often was usually at the bottom of the screen (with old style VDUs and shitty/awesome text only terminals) and so the suggested eye line was lower than it is now.
I don't think the advice has ever to have the eyes level with the top of the screen (although that may be the eventual position given an individual setup and the next piece of advice...)
Now the common advice is that the centre of the screen should be about 10-15 degrees down from the eye level. In other words, you probably want to have your eyes level with about 3/4 of the way up the screen.
But it really does depend on your individual situation though, and what you are doing. I want to be looking at different points on the screen depending on what I'm doing. My email client has the list of emails in the top half of the window, and the text of the emails in the bottom half of the window. So if I'm responding to emails I'm mostly looking at the bottom half of the screen, but if I'm clearing out my inbox and filing emails I'm mostly looking at the sender/subject info and not the content, and so I can spend 30 minutes just looking at the top half of that window.
If I'm coding I tend to look at the middle of one window (when editing the code) and the bottom of the window when compiling and looking at output.
There is no magic hard and fast rule that works perfectly for everyone.
It's why I went for a really big screen (43") so I can have multiple things open, move the windows to suit, and even move myself around to see the different bits (sitting on a 'wobble stool' helps me do this easily, as does having an adjustable height desk).
It basically exists in Occulus desktop, you can give yourself a desktop that is larger than your entire field of view if you want, as wrapped or flat as you want but obviously involves wearing a headset
