What about distant focal work (focusing your eyes on clouds, etc)? It's weird that illumination should have an effect and training focus variation doesn't?

  Focusing on clouds is not much different than focusing on the other side of the room.

    I don't know, I'm looking at the other side of my room right now and I can definitively see a lot of difference (additional blur) by trying to extend my depth of field. Maybe I'm focusing past infinity though.

      How can you extend the depth of field of the eye?

      Subjective experience does not always match with scientific fact.

        Blanket statements do not always refute arguments.
