I don't wear them in front of a screen because they reduce contrast an there are reflections - however clean they are. But I wear them to drive home.

As far as I am concerned I have evolved from something that needed to spot lions on the horizon to something that needs to spot trolls 0.5m away

That makes sense, but for me it would be more convenient if I could wear glasses while using the computer and not while doing other activity, which hopefully will be possible with the research that's going on.

Wait for old age! As you age your ability to focus closely gets worse (the eye muscles weaken) but your distance vision generally doesn't change much.
