If we use our computer or laptop screen for 10 hours a day for decades, our eyes are going to optimize for that distance (1 to 1.5 feet). Over time, we are going to lose our distance vision and near vision.
This is the "use it or lose it" theory of how our body works. This happens for many muscles in our body so why wouldn't it happen with our eyes?
So, I set out to find out.
A few months ago, I set my 27 inch monitor about 5 feet away but left the fonts at the usual size. At first, it was a little uncomfortable. But now my eyes seem to have adapted to it. In fact, my far vision seems to have improved (tested against a mini eye chart at 10').
I am going to move the monitor further away gradually and also intentionally read books at a close distance.
Check back in a year.
