Blood Vessels

    Someone else asked this on another forum, and it made me wonder. When
    you shine a very strong light like the focused rays of the sun using a
    burning glass on your sclera, how is it possible that blood vessels
    can be seen, which are inside the eye, when things from a range of
    less than 1cm in front of the eyes are usually difficult or impossible
    to see or focus on? Wouldn't it take an enourmous accomodative power
    to see blood vessels in the eye themselves?

    Just curious, Thanks!

    I expect that one possible reason for the visibility of the blood
    vessels is that YOU ARE BURNING YOUR EYE!!!!!. Blood flows to the site
    of an injury.

    Along the same lines, I expect that if one were to take a sharp object
    and penetrate the outer surface of the eye, one could acually see the
    vitreous humor as it seeps down over the outside of your cornea. How
    much less sane is the notion of puncturing your eyeball as the notion
    of deliberately focusing a burning glass onto its surface?

    You are not seeing the vessel by accommodating, you are seeing their
    shadows which are falling directly on the retina.

  8. I know this is being gratuitiously picky, but do you have
    any evidence that s/he was once not "off the deep end"?
    S/he cannot "go" where they already are.
    This is just the latest and clearest sign.

    Many people who need mental health professionals resist any notion
    that they could benefit. This makes most therapies ineffective.
    Like the joke:

    "How many psychs does it take to change a lightbulb?
    -- Only one, but the lighbulb _really_ has to want to change."

    Best suggestion I can offer is that once you type a big shouting-match
    message in all caps, freaking out like that.. always (*Always*) walk
    away from it for at least a few hours before hitting that Send button.
    You might come back after a few hours and decide you really don't want
    to say what you'd thought you'd wanted to say.

    I have other suggestions (like maybe calm down just a smidge and don't
    take things quite so personally), but I expect that immediately
    practicable suggestions would get more traction than ones concerning
    perspective.

    Too bad you decided to share that. Next time you blow off, you'll be
    taken even less seriously by the general populace of the group,
    because now you've come out and admitted that you blasted people on
    the group because of something that had absolutely nothing to do with
    the conversations *in* the group.

    The *least* you could do is to offer an apology to the individuals
    that you "all-caps'd". The adult thing to do would be to apologize on
    the group, and also privately, just for an added gesture of sincerity.

    Just my opinion, though.

    Trying to figure out where the problem lies. An adolescent (subolecent?)
    arguing with adults or the adults arguing with the whatever.

    Why are you all even posting in my thread?????
    The question I asked has been resolved. I asked how it is possible to
    accomodate on something so near as blood vessels. Then I found out
    from Mike and Judy that it's not actually the blood vessels but
    actually their shadows. This topic has
    ended!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Somebody's going/gone off the deep end.

    Please reach out to Otis, directly. Perhaps the institution that
    cares for him has additional vacancies....
