    Otis> But you are in NO POSITION to

    Neil> Your nephew has a fool for an uncle.

    Otis> Your opinion -- of course. He simply
    followed the scientific analysis of the eye's behavior
    as proven by the primate studies. This is of course
    the second-opinion -- and he was wise to understand
    it that way.

    Otis> He also has run the Iron-man, and looks
    after his personal health. At his last
    check he had better than 20/20.

    Otis> At 12 years of age he was decleared "nearsighed".

    Otis> The records at both Annapolis and West Point
    show that the fundamental eye goes "down" in a
    four-year college. At West Point, the rate
    is -1.3 diopters for four years, with the
    spread of -1.1 diopters to -1.6 diopters.

    Otis> If he had not worn the plus (and verified clearing)
    he would be at about -2.0 diopters today (about

    Otis> To bad we don't have more people who
    actually SUPPORT us with true-prevention
    as Steve Leung OD is now doing it.

    Otis> You don't like true-prevention? Find, don't
    use it, and develop stair-case myopia. No
    skin off my nose.

    Shotwells study at the Naval academy show no myopia prevention using
    plus OR bifocals. just give it up Otis. your understanding of the
    literature and the state of myopia research is fragmentary at best!


    Am J Optom Physiol Opt. 1984 Feb;61(2):112-7.

    Plus lens, prism, and bifocal effects on myopia progression in military
    students, Part II.

    Shotwell AJ.

    Military academies routinely lose a percentage of their
    pilot-qualified students to myopia during the 4-year academic program.
    This study investigated the progression of myopia during such a program
    and evaluated the usefulness of reading glasses to prevent myopia
    progression and subsequent acuity loss. A group of students at the
    United States Naval Academy comprised three randomly divided groups: a
    placebo group (no. 1 pink tint), a plus with prism group (+1.25 D with
    2 delta base-in each eye), and a bifocal group (+1.50 D near addition).
    All the lens powers were relative to the experimental subject's
    distance refraction and were for use full-time when reading. The pre-
    and post-test refractive errors at distance were determined using 1%
    tropicamide HCl. At the end of 4 years, the tropicamide refraction
    showed approximately -0.25 D of myopic shift in all groups. There were
    no significant differences between the myopic shifts in the controls
    and experimental groups.
