I don't agree with this at all.  Ergonomics suggests that everything we
might look at should be at the same focal distance to reduce eye strain.
You can get a feel for the problem by holding a finger at arms length in
front of you alternately focusing on your finger and something further
away.  After a short time, your eyes will start to hurt.  Holding your
finger closer will accelerate the problem.

What you really want is to have the monitors, work surface (all those
listings), keyboard and mouse all the same distance from your eyes.

Turning off lights may help reduce strain while looking at the screen, but
it is going to increase strain when trying to read those listings in the
dark.  Get a desk lamp to help light up your reading materials.
