    Could you please confirm that looking at a 30" TV from a distance of 3
    metres (about 3.5 yards) with a 3X binoculars is not harmful to the

    I found the following at misc. low vision what to do.htm

    "Using magnification and looking at books, lenses or screens will NOT
    damage the eyes."

    Thank you,

  2. It depends on what amount of strain you put while watching into the thing.

    Looking at TV, from any distance, with or without magnification will not
    harm the eyes. The only time that looking at anything is harmful, is when
    the object has a high level of UV or IR light for example, staring at the
    sun, at a welding torch or into a glass oven.

    I am sorry you are wrong here.

    _Looking at_ the sun is not harmful in any way.
    *Staring* , at the sun or at every other object (even with
    eyes closed!) is very harmful to one's eyesight.

    It is not light but the strain that is dangerous.

    People who can look at anything without straining and maintaining
    central fixation will get benefit even from unfavorable conditions
    like the strong light of the sun or of an arc welder.

    Do you think that the light from an arc welder is dangerous to the
    eyes ? It is not, I can look at it without any damage, but with

    Do some people injure their eyes staring at it ?
    Of course they do, but the cause is the strain not the strong light.
    I can teach them how to maintain central fixation and avoid strain
    and they will look at it without any injury.

    You also could teach them how to do it once you understand
    and demonstrate to yourself the principle of perfect sight.

    Might cause some temporary fatigue ( as would holding your arm in one
    position for hours) but will cause no damage or harm.

    Lots of people, for example truck drivers, pilots, computer workers, factory
    line workers, artists, home crafters look at a fixed distance for hours on
    end. No harm.

    Dear Dr. Judy,

    Then you can confirm in an absolute sense, that
    if an individual has a refractive status of -1/2 diopter, (20/40)
    reading with a plus 2 diopter (spherical) lens (at 20 inches) will
    have NO EFFECT on the refractive status of his
    eyes. Is that correct. That process would by totally
    ineffective -- but harmless.

    Or could any "harm" be caused by such use of a simple
    reading glass?

    I know of no placebo controlled human research that shows that wearing (or
    not wearing glasses) while reading has any effect on refraction.

    Are you talking about a low vision aid or regular binoculars? Either way, Judy is
    correct- you will do no physical damage (or physiological) damage to your
    eyes or vision by using a 3x binoc watching the tv (especially if you are a
    low vision patient).
