    Please don't shoot the messanger! I am only the mail delivery person.

    At first glance the article sounds like "astrology", but reading it,
    and knowing who had conducted the study, it might make some sense.

    "The team interpolated data from a sample size of almost 300,000 young
    adults, making it one of the largest epidemiological surveys carried
    out in the world on any subject." This is impressive!

    Also astonishing (and statistically significant) are the results:
    "Babies born in June and July had a 24% greater chance of becoming
    severely myopic than those born in December and January -- the group
    with the least number of severely myopic individuals. "

    The researches hypothesized not on astrology, but on a more sound
    theory: "We know that sunlight affects the pineal gland and we have
    indications that melatonin, through other compounds, is involved in
    regulating eye length," says Belkin. "More sun equals less melatonin,
    equals a longer eye which is short sighted."

    As I said, I am just the mail delivery person. But here is a thought
    that came to my mind:

    Most babies nowadays are being born in hospitals with very bright
    lights, unlike in the past where they came to the world in dim-lighted
    rooms. Right from the darkness of the womb they are exposed to
    cruelly unbearable lights at a very crucial moment of their lives.

    Could that be a factor in their future development, mainly on their
    vision? And could this explain, at least partially, the increase in
    myopia rate in recent times?

    I don't purport to have the answers. I am only thinking, wondering
    and speculating about a possibility.

    ok so u were actually bein serious was u? i thought u wz jokin!

    u have a sorta good point with the babies bein exposed to a bright
    light from the complete darkness, but i dnt see how these shd affect
    axial length myopia or nething... anyway bright lights r nt harmful to
    the eyes, and any damage is almost always temporary and onli rarely is
    it permanent.

    an u are forgettin one very important truth here coz sudden changes
    and contrast in light and brightness r nt only NOT harmful 2 the
    vision, but in fact the quick and rapid changes r something that the
    eyes enjoy an it is very beneficial for the vision. so u r wrong in
    all aspects im afraid... an ur theory dnt make sense at all or fit
    with the facts....
    well duh... andrew an me waz jus humouring with ya mate.
    well im sori to break ur little bubble of speculation, but it dnt work

    Babies born in June and July had a 24% greater chance

    hav u considered weather conditions? coz it is hotter in june and july
    than any of the other months so it might jus b bcoz of the weather...
    i mean like the babies feel uncomfortable in the hot weather were it
    is so dry and different from the normal condition in the womb of the
    mother.... u kno wat i mean

    and discomfort of the body is a major factor of strain in the mind, so
    that means that the babies get more strain in the mind which leads 2
    the worse myopia. in science simple explanations r alwayz the best,

    Ms. Brainy, it might not be quite as crazy as it sounds. There's also
    evidence that babies born during the late winter and early spring have
    a significantly greater chance of developing schizophrenia during
    their lifetime. This finding applies both north and south of the
    equator, although the months of winter and early spring are
    different. It's hypothesized that a virus during the second trimester
    of pregnancy may be to blame.

    But the research you sited is another correlational study, so maybe we
    should withhold judgment for the time being.

    ...and besides, the authors are talking about severe myopia, not all

    Huh? The more sunlight you experience the MORE melatonin you develop.
    There's a reason that Africans are dark and Norwegians are light. Let's
    think about this for a while...

    So if Belkin is right in spite of his wrongness, how much melatonin (not all
    that expensive at Costco) do I have to take to reduce my +3 and +5 eyeballs
    to perfect planosity? Should I undercorrect the +5 or overcorrect the +3?
    Decisions decisions decisions...

  13. cruelly unbearable lights at a very crucial moment of their lives.

    And not just that.

    Prematurity is associated with myopia.

    As is being first born. First children are often the experimental
    child till parents figure out what to do. They can also be spoilt and
    over prtoected which then leads later to anxious behaviours when the
    real world intrudes on the an unrealistic family environment.

    This suggests quite a strong possibility of some factor influencing
    the baby that in turn leads to myopia.

    For decades it has been argued by the behaviourists that insecurities
    of the kind brought about by difficult early experiences are a major
    factor in myopic development. If for no other reason it could lead
    to a withdrawal towards "bookish" or intellectual behaviours where
    distance place is avoided.

  14. Actually Zetsu has a point here.

    Maybe even in womb foetal distress could be relevant as the summer
    season approaches, but the hotest month is August and in the middle
    east this would probably extend into September.

    Perhaps a child born in early summer gets pivotal experiences in
    intense unpleasant heat that in some manner stress it?

    what does any of this wild speculation have to do with (S)cience or

    you should go off to some other forum where proof and facts are not
    relevant or important.
    p.clarkii, Sep 1, 2007
  16. Science is open minded before it is narrow minded.

    "Proof and facts" are often founded on poor science and narrow minded

    People tend to ridicule what they cannot believe.

    Science gets there in the end.
