Increase in Myopia may be due to increasing testosterone...

    It is my hypothesis that the "secular trend," the increase in size and
    earlier puberty occurring in children, is caused by an increase in the
    percentage of individuals of higher testosterone. More specifically, I
    think this is driven by an increase in the percentage of women of higher
    testosterone giving birth within the population. Exposure to increased
    maternal testosterone may be the cause of the parallel increase in numerous
    phenomena such as diabetes, obesity, breast cancer, etc., including myopia.
    Black maternal testosterone is known to be higher than white and this fact
    explains the higher incidence of myopia and increase in myopia among blacks.
    Testosterone has been connected with myopia.

    "Results Using the 1971-1972 method, the estimated prevalence of myopia in
    persons aged 12 to 54 years was significantly higher in 1999-2004 than in
    1971-1972 (41.6% vs 25.0%, respectively; P < .001). Prevalence estimates
    were higher in 1999-2004 than in 1971-1972 for black individuals (33.5% vs
    13.0%, respectively; P < .001) and white individuals (43.0% vs 26.3%,
    respectively; P < .001) and for all levels of myopia severity (>-2.0
    diopters [D]: 17.5% vs 13.4%, respectively [P < .001]; -2.0 to >-7.9 D:
    22.4% vs 11.4%, respectively [P < .001]; -7.9 D: 1.6% vs 0.2%, respectively
    [P < .001]).

    Sounds like Dr. Tyner was correct, then: myopia is less common in
    blacks than in whites, though the gap may be narrowing

    Otis? What do you make of this? Think black people have discovered
    the secret of plus lens therapy??

    Dear Mike,

    Why ask me? You have declared that you will NEVER LISTEN TO THE
    SECOND-OPINION.

    Why ask now?

    The people who have their own trial-lens kit, and verify their
    refractive STATE themselves, simply clear their vision when necessary,
    and keep their refractive STATE close to zero.

    Thus avoiding "stair-case" mypopia -- permanently.

    It is never "easy" -- but it has been done, and continues to be done
    by the people who have the motivation for it.

    Prevention best,

    Otis

    He didn't. You're an idiot.
    And the people who spray Shark Away in their front yards .... have
    never had a shark infestation in their front yards.
    The issue isn't difficulty. It's efficacy. Got any evidence of that?

    Your nearsighted niece, Joy Benson .... is probably something we
    should discuss.

    Dear Mike,

    As you might recall, I never said "CURE".

    I said avoid entry into a negative refractive STATE.

    Thus, prevention must be under control of the Engineer/Scientist
    (i.e., a person like Dr. Stirling Colgate) who "wakes up" to the fact
    that the eye is dynamic, and, that your are destructive to the goal of
    effective (threshold) PREVENTION.

    Engineering/Science best,

    I must have missed the part of this that was supposed to look
    like .... evidence.
