It's a virtual certainty that Otis hasn't read ANY paper that doesn't
support (a pretty broad statement, considering his tenuous grasp on
reality) his preconceived notion.

If he does, he never admits to them -- though he occasionally does
reference papers and snippets that contradict him, directly.

Perhaps more than occasionally.

Here's a good starting point:

Thanks for the input. So you're saying there is definitely a
correlation between a lot of close work and myopia, but we have so far
not found a way to slow it down? Does the consensus think it's a
causative relationship merely a statistical one?

Do you have the name of that paper you mentioned that Otis hasn't
read? Wasn't sure if that was a figurative statement or not.

Also, about the double vision question I had, I meant that I see a
double effect on horizontal edges, not sure if that matters. The left
script was -0.75/-1.00/02. I've been noticing it though to a certain
extent in my "better" eye, and in most lighting conditions. What
worries me is that I can definitely make out two lines of text on a
computer monitor even in the eye that had only a spherical script. I
could just be over thinking this a lot, but it would seem to me that
even more minor astigmatisms make things like reading take an
unnecessary amount of effort because it's so much harder to perform
edge detection. I've always dealt with not being able to sit down and
read for significant periods of time despite being very academic.

I'm one of those who is used to spending money on heathcare only to
see my problems not get resolved - so I guess I'm trying to figure out
if I should get a follow up eye exam so I don't end up wanting a
revised prescription later. On my first visit, I didn't ask to be
dilated, so I'm not sure if that makes a difference as well.

Thanks for all the help,

-David

Spectacle cylinder ("football" shape) is a mathematical model that only
approximates the real-world maps you see in corneal topography.

From your rx, we know in one eye, the closest approximation was a sphere. In
the other eye, the best model was toric. We use those simple models because
that's how you can cut real lenses.

Sphere or sphere-cylinder, you can see from corneal topographs that it's
more complicated - there are peaks and valleys and plains.

It's the plains that matter. If there's a big plain of uniform 45-diopter
surface on the left half of your cornea. it'll form a precise image at the
retina. If there's another big plain on the right half of your cornea, it
can be precisely the same power (45 D) without being precisely _coaxial_ so
that it forms another crisp image slightly offset from the other.

Ergo diplopia, a type that increases in dim light and disappears with a
pinhole.

No, this thread has been blissfully FREE of that old crap.

Otis insists all myopia results from accommodation and that parents have a
duty to put drugstore glasses on children to prevent myopia, or to cut their
myopic correction so they can't read a blackboard. All with the intention to
avoid further myopia.

I can't find any licensed doctors that agree with him. The ones I can find
say reading glasses don't prevent myopia.

Myopia is mostly due to the eye growing longer than average. The control
mechanism for axial growth does not appear to involve accommodation, because
manipulating accommodation with glasses/no glasses/plus glasses all have no
effect,. At least not enough to warrant intervention..

Otis hasn't read that paper yet but Otis doesn't have to keep a license
current.

That's right. Myopes read a lot and readers get myopia but we haven't been
able to interrupt the relationship with reading glasses or any other
manipulation, except chemical. Ergo the tendency to myopia is mostly a
genetic trait.

If you could manipulate or alter the outcome of ordinary myopia with glasses
or treatments, I'd be doing it. I would patent my treatment, franchise it
and retire to the lake.

"Mild" cases of myopia are a blessing, a serendipitous adaptation that many
people are glad to have after 40, when hunter-gatherers put down their
spears.

Most people can detect some diplopia or other aberration in dim light.

Work hard, rock hard, eat hard, sleep hard, grow big, wear glasses if you
need 'em.

.... except, perhaps, for "pseudomyopia," or ... "accommodative
myopia," or ... "accommodative spasm," or ... whatever you call it.

It can become 'semi-permanent,' but there's no evidence that it
changes the shape of the eye -- even over time.

Plus ... my "protocol" is a pretty sound way to avoid even the
accommodative myopia ... and ... it don't cost nothin' ;-)

That one's pretty obvious, other than the hills and valleys, of course.

Many people have found that staring at a computer screen for long
periods of time causes problems. Just looking up and across the room
occasionally will solve this problem. Some people even set a timer to
remind themselves. I find that getting up and walking around makes me
feel better, as my whole body seems to dislike sitting in one position a
long time. It is important to note though, that despite the preachings
of Otis, none of this has anything to do with causing, preventing or
curing myopia.

At this point, a quick e-mail to Otis seems very relevant ... since he

I made a little typo about the Sun/Earth thing above, but I trust
you'll in good faith forgive me .

Also, as for the anal sphincter thing - and I think it was discussed
as much as a joke as it is a serious corollary - what you said brings
up a good point of distinction. That muscle feels more strongly
contracted (as a matter of force as opposed to distance) when the
rectum is full than otherwise. The way I understand it, if we hold
for a moment that long periods at close distances aren't natural,
sitting at a computer all day (at the age of 24) might be better
compared to mildly needing to pass a bowel movement and withholding...
for 10 hours a day... every day . This comparison makes quite a lot
of assumptions, but I think there is probably a focal distance and an
age group where this makes sense.

Oh I read the line at the DMV, but just had a shock that I almost
could not because it was totally blurry. So in that respect, I just
want to do what's best for me. I'm fairly excited though because I
can't read street signs from too far away when driving, and my wife
with glasses can - so that's something to look forward to. I'd also
perhaps like to look into correcting the astigmatism for close work (I
think at my script the same glasses should be fine though) - because
I've always dealt with focus (concentration) issues, and the thought
has occurred to me that I may be struggling because it takes more
effort than normal to make out the letters, as my mind is removing the
double vision. This last thought though is slightly less informed
than some of the other statements I've made.

As for the Pope - any physicist will tell you that it's just a frame
of reference . The reason we say the Earth revolves around the Sun
is not because the Earth is the fixed body in the equation, but
because there are other bodies following a similar path around the Sun
that from a broad perspective make more sense to describe as revolving
around the Sun and not vice versa.

As for the earth being flat....
