> get this one very wrong, recommending a display with eye level somewhere around the middle of the display Maybe this is because I wear glasses and don't move my eyes much (tend to move whole head when shifting gaze because looking through center of glasses works best), but when my monitor is low, it eventually causes strain on my neck and shoulders. It also causes me to slouch a lot as I try to fix the positioning subconsciously. Before I had a monitor with a riseable base, I used to put my monitor on a book or two.

In general people can keep their heads upright and balanced above the spine. It is not in general necessary to move or turn the head to look slightly downward. No idea about glasses though.

  Your recommendation doesn't take into account monitor size. If you always keep the top at eye level, the larger a monitor you get (assuming same distance away), the farther and farther down most of the monitor will be. Monitor sizes have grown a lot over time.

    I have a 27 inch display, and the top of it is easily 6 inches below my eye level. It is about 3 feet away from me, so about 5°–35° angle measure below my eye level from top to bottom. It’s perfectly comfortable to see the whole display without moving my head from an upright position. Put the display on an VESA mount attached to an articulating arm and put the bottom of the display bezel directly on the table or slightly above. Maybe if you have a 40 inch display it starts getting tough.

  Was curious and decided to test it out. Swiveling my eyes horizontally works great, no head movement needed unless I'm looking at the far edges of the screen. Up-down, I move my head almost immediately. My understanding is that glasses have an optimal viewing angle centered around your pupils where your perscription is perfect. As you start looking through different parts of the lens, it gets less perfect. At extreme angles you start seeing the frames themselves and it's annoying.

    Freeform and digitally surfaced single-vision lenses have less peripheral distortion away from the optical center of the lens. Round/oval metal frames will reduce visibility of the frame edge, if the frame fits well and the eye size is tall enough. Lenses: Essilor “Eyezen+ 0” CR-39 lens+AR is ~$120 online or Zeiss Individual SV ~$300. If you have prescription with sphere stronger than -3, the improvement in peripheral vision can be useful for large or multiple monitors.
