Can you trick your eye into long range mode?

    I was thinking about using a large picture of a outside scene that
    looks far away and looking at that while at my computer. In theory
    would that work for relaxing my eye strain? Maybe a sunset or other
    landscape. I figure if looking outside a window your eyesight is not
    stopped or hindered by the glass anyway this theory could work. My
    theory is based on the looking at far away scenes is relaxing on your
    vision since looking at close objects puts strain on your eyes.

    My guess is no. What might work is getting a "magic eye" picture -- to
    see those you have to focus past the actual picture, which is apparently
    what you want to do. You can probably even find one that you can look
    at ON your computer. It's also possible to see your keyboard as a magic
    eye picture, with each key having two simultaneous labels.

    I had wondered along these lines too. If you look in a mirror, the
    image is supposed to be as far behind the glass as the object is in
    front of it, so presumably your eye would focus for distance if you were
    looking at a faraway mountain in the mirror?

    And if that is correct, if someone was to replace the mirror with a
    photograph, or a very realistic painting, why wouldn't your eye be

    What happens if you hold something up close to the mirror or painting,
    but focus on an object in the mirror that should be some distance away?
    If the close object goes out of focus, then I would guess your eyes are
    seeing the mirror or painting image as distance.

    Incidentally, there used to be a computer programme that produced random
    dots on the screen, and if you were long sighted, the dots moved in one
    direction (up or down - can't remember) if short sighted they moved in
    the opposite direction. It was supposed to train your eyes back to
    normal. One was supposed to have been given to Prince Charles for his
    long sightedness, and there was some publicity a few years back, but not
    heard anything about it since.

  4. But why don't you use a simple Snellen eyechart, to be placed on the
    wall at 10, 15 or 20 feet and look at it?

    Of course, you should look at the eyechart without glasses.

    It is the only method really useful, both for people with perfect
    sight and for people with imperfect sight.

    Can't place one at work that way.

    If the picture is the same distance as the computer, your eye will need to
    focus on it exactly the same as it needs to focus on the computer screen; if
    it doesn't focus, the picture image will be blurry.

    Looking at distance objects relaxes accommodation only if the objects are
    actually at a distance.

    I would disagree with your idea that looking at near objects strains the

    Dear Judy,

    I agree 100 percent with your statment.

    The accommodation system must remove micro-blur
    on the retina (as a control-system).

    This means that the value of the accommodation
    system (in diopters) is equivalent to the eye-to-target

    If the reading is done at 20/inches, accommodation
    is at -2.0 diopters. At 6 inches, -6 diopters,
    at 4 inches, -10 diopters, and 3 inches -13 diopters.

    It is difficult to assert reading at -13 diopters
    for hours on end has no effect on the refractive
    status of the natural eye -- but you keep on insisting
    in making that statement.

    I can do this trick quite easily by "looking away _through_ my computer screen"
    and the text on the screen changes from "blurry" to
    "crisp". I noticed that this trick works only with one eye open,
    when both eyes are open this is not easy (I think when doing that trick
    I see double vision because of wrong vision convergence).
