To prevent your eyes muscles from going lazy and thereby progressively worsening your eyesight I propose a computer monitor stand that utilizes a chain or a hinge from which the monitor swings freely.
This idea was inspired by Juran's eye gym idea. Always looking at a static monitor from the same sitting position does for our eyes (depth at least) what a sedentary lifestyle does for the rest of our muscles.
People spending a lot of time on the computer could periodically swing the monitor. That way their eyes get to work out while tracking/zooming on the details. Of course, it would be annoying if the monitor moved all the time, so it's up to each individual's preferences to determine how much workout their eyes need.
Optionally there could be a small motor added to the top of the swing. It would periodically get the monitor moving without asking for the user's permission. The rationale being - sometimes we are our own worst enemies and can't rely on discipline alone.
I'm building this and will update the header image when done.
