    Dear John,

    Subject: 43 percent of normal eyes have diplopia.

    1. Monocular Diplopia Caused by Ocular Aberrations and Hyperopic
    Defocus. Russell L. Woods, Arthur Bradly, David A.
    Atchison. Revised March 1996 Peragmon

    "... The second type of monoculary diplopia, however, seems
    to be much more common, and perhaps present in most eyes. Studies
    of otherwise normal eyes indicate incidences of monoculary
    diplopia of between 43 percent (Fincham, 1963)..."

    Dear Alex,

    The text is fuzzy, so I can't copy it.

    I will type up some of it and post it
    here when I get some time.

    The implication is that eye with
    VERY SHARP vision have some
    "ghosting" or diplopia.

    I will state the author's location
    at the time of publication, and
    a correspondence author.
    With most of these scientific
    publications the author
    is pleased to discuss his paper
    with you.

    Best,

    Otis

  4. What about the remaining 57 percent? Yes I used to be in that 57%.
    Again, you better hope I don't have diplopia, or maybe start a research
    how I can get rid of diplopia.

    Dear Myopia prevention friends.

    I have received the following on "ghosting" for your
    interest. Since this is a private email, I will change the name
    of the sender.

    +++++++++++++++++++++++

    Dear Mr. Brown:

    I have been following with great interest your latest
    postings on "Ghosting" or Diplopia. My main reason to contact you
    at this point is my concern that John may be commiting an
    error for something he can overcome by continuing
    with his vision therapy.

    As it happens, in the process of restoring my vision, and
    struggling with a stubborn astigmatism, I have noticed "Ghosting"
    in both eyes. In my worst eye (Right) the ghosting has actually
    changed. Originally the ghost image was at 11 o'clock position.
    As my vision improved, the ghost is now at 3 o'clock position, and
    disappearing. The left eye also has some ghosting that still
    shows up occasionally. I know it is related to the astigmatism in
    my eyes, because the astigmatic mirror tells me so. I have my own
    ideas as to why this is occurring, but the point is that I am
    getting rid of the ghosting.

    While there has been some discussion about John's complaint
    and his ghosting or diplopia, I am not aware he has had a thorough
    diagnosis. Unless I have missed those posts. Maybe the
    information at the following link:

    http://www.optometry.co.uk/files/2c8b0cc4c7b2636385085b3991c9f03e_finlay20001006.pdf

    maybe helpful, if John is not aware of the whole diplopia
    issue.

    Regards.

    Jo

    Is ghosting less prevalent in the artificial eye?

  8. Kindly ask the sender post here. I have no diagnosis of diplopia, but
    you admit that plus lenses introduce diplopia, which is a defect, to
    one's vision, this is not acceptable. What am I supposed to see in tis
    study paper?

  9. Otis, I have received your email. Kindly ask this "Jo" person to email
    me if he needs to point out certain facts about my ghosting in the right
    eye. Better yet he should come and visit SMV. Unless it is public
    discussion where ODs can see and verify, I have no interest in these
    dialogues.
