There are also vision exercises on youtube:

It is totally possible to improve your ability to focus visually using these. Just doing them on occasion, or once a day for a few minutes can be enough to counter the negative effects of staring at a screen all day.

Wow. Thanks! Just one minute of each of the seven exercises has improved my vision to the point where I no longer need my 1.0 reading glasses to read hacker news on my iPhone 7+. The improved vision seems to be lasting at least a few minutes. Perhaps there’s truth to the “use it or lose it” theory of vision?
