Part of how myopia works: When your peripheral vision is in focus too much, because something is close to your face like a screen, your eye (which grows on its own, without brain involvement), is told to grow longer to to help reduce the over sharpening of the world it thinks it has. This happens in developing humans, at some point in adulthood it's suspected this stops (although some people see worsening myopia past the typical age range where it stops).

would it help to keep your phone or monitor further away?

  Having less focus in your peripheral vision might help slow myopia progression, so possibly. However wearing glasses and contacts automatically add more focus to peripheral vision, signaling the eye to grow. So moving something further away from your face while wearing glasses or contacts may have less of an effect. Having periods of blurry vision, like looking at something far away for some time without glasses or contacts, may be beneficial in that it may signal the eye to become less football shaped to help correct for the blurriness it now is experiencing. However I haven't seen any evidence this can reverse or improve myopia, rather this just seems to slow its progression.

I literally just had that yesterday, and was wondering what it was. My eyes have always been very good, but I have been a bit worried of late after a few such blurry episodes...

      no, I mean intentionally unfocusing your eyes by looking at something far away without wearing correction. Involuntary blurriness or double vision is unrelated.
