Amazon offices use absurd amounts of paper.... however it's mainly for raising desks and leveling monitors. Literally every desk has some thing up on a ream of paper. The actual paper document culture is moving online finally.
Most people also position their monitor too high, to be fair. The top of the monitor should be at or slightly below eye level. If you reach out from your chair with your arm held level, that should be roughly in line with the middle of the screen, and your fintips should be ~10cm or a few inches away from the screen.
I very purposefully position my monitor so that my main console window is viewed, with my head level. It is also horizontally centred on the mid-left of that console.
This is because most text, eg bash work, vi of files or code, rests there.
In this way, my head is not tilted down, or eyes tilted down constantly. My head is mostly centred, and looking straight ahead.
I find that elsewise, my body follows the constant downward look, either slouching or the neck bent forwards.
Why do you belief your monitor should be positioned, so you are looking downward constantly?
Multiple ergonomics guides give the guidance I mentioned. Here’s a link to a few, but I encourage you to do your own research.
At the end of the day, if you’re finding that something helps to reduce long-term fatigue then it’s probably not too bad, but don’t forget that slouching in your chair feels good however it’s terrible ergonomically - this is similar. Comfortable short term, but not always long term.
All of these recommend at or slightly below eye level:
Of course though, because the monitor and keyboard should be able to be raised and lowered independently. If you set the desk to a height that's suitable for the monitor, it may be too high for the keyboard.
