Otis - 23 Jun 2009 02:42 GMT Dear Bill,
As a Ph.D. Engineer, you are going to be interested in scientific facts, and not all the "fluff" that exists on this site.
To read Chapter 6 properly, copy it and then paste it into a "text" file.
The quality of the graph will be restored.
This is a pure and objective test and confirmation that the fundamental eye changes its refractive STATE with an applied "delta" to its average enviroment.
You also ask for a test of the "null hypothesis", versus the "research hypothesis".
Engineering/Scientific Analysis Best,
Otis
Otis - 23 Jun 2009 03:05 GMT Dear Bill,
Subject: A direct confirmation for the effect a minus lens has on the fundamental eye.
Here are the results of that scientific test of a population of natural eyes.
http://myopiafree.i-see.org/FundEye.html
When I wrote the analysis of the primate eye (Francis Young's experiment) the above data was not available.
It is now.
This strongly confirms Soon's general graph FOR PREVENTING ENTRY AT THE THRESHOLD.
I believe in looking at the facts themselves, as an engineer.
This is convincing to me, as to the dynamic behavior of all natural eyes -- to the extent that we can have a repeatable scientific experiment.
But you are free to form your judgment.
If you wish to contact the author (Dr. Smith) I think that could be arranged -- as a matter of pure science -- if you don't believe these results.
Enjoy,

I have come pretty much to the same conclusion you did. Pleas do not continue selling the concept to me. It is now time to get experimental fact. Your choice of the Soon curves seems to show the path to understanding. It does seem, as some others have argued, you are more interested in controversy than in fact.
The idea of measuring refraction as a function of timer correlated to the steps in corrective power strikes me as a dream topic for someone interested in the subject. One questionable publication is just not sufficient. IT MUST BE REPLICATED FIRST!

Otis - 23 Jun 2009 13:03 GMT Dear Bill,
Let me pose this analogy.
You wrote your Ph.D. thesis on a difficult subject.
It was written in a technical style, and few layman would ever understand it.
If you posted it on sci.med.vision -- it would be ignored, or "not understood".
Plus-prevention (as Stirling Colgate did it), is not easy. The average person not only has NO INTEREST but, as you have seen on sci.med.vision is rabidly hostile to plus prevention.
There is no way you can expect Soon See to "overcome" this rabid hostility. Why would you expect Soon to do it???
The only issue is this:
Was Dr. Colgate's report (clearing Snellen can changing refractive STATE from slight negaitve to positive) correct as Science.
As far as I am concerned, the primate data (bi-directional response to an applied -3 and +3 diopter lens) is SCIENTIFIC CONFIRMATION.
In as much as the general public will not understand your Ph.D. dissertation, I equally would not expect people who are hostile to Soon's graph, to "understand" any of it.
SOON'S GRAPH:
Let me add that this graph came from a Dr. Flitcroft, who publishe a more detailed analysis and discussion.
So don't think or say that ONLY Soon publishes this analysis. There is great depth in this "curve" of his -- but due to the hostility of the public, you truly can not expect him to accomplish successful prevention.
Just read the remarks of the resident nit-wit -- as final proof for that issue.
Best,
Otis

You still are missing the point. What is the the process that your cure is trying to correct. You are trying, to use an analogy, to prevent heart attacks before you have shown that blood circulates. Maybe eating foxglove will help, but you still would not know what you are doing.
Your Soon posts show a clear path toward understanding what is happening. If it has not yet been established within the biological literature, it is a great research topic. Even if someone else proposed it, it needs competent replication. That is it!

Otis - 23 Jun 2009 14:26 GMT Dear Bill,
I have NO PROBLEM with instituting a preventive effort.
But it would have to be a person of wisdom, who could couple his desire success (and ONLY from -1 diopter) to a professional goal.
The nature of plus-prevention, is that the person must do it correctly UNDER HIS CONTROL.
Do you think, for instance, that Neil D. Brooks would be involved in a preventive study conducted by Soon????
If you do -- please explain how that would even be possible.
But, yes, provided each person in the study would read Dr. Colgates analysis and obvious success, as well as the primate data (before there was even A START to the preventive study) then I believe that a professional could reproduce Dr. Colgates success.
I will post a proposed study for true prevention for engineering/ pilots (at -1 diopter) who have the greatest INTEREST and above all else INTELLIGENT MOTIVATION for it.
But there is no hope at all for people who wish to "trash" the primate data that I posted.
Yes, the minus is indeed POWERFUL AND IMPRESSIVE FOR THE SUPERFICAL.
If you want it -- I certainly will never stand in your way and you lunge for it.
In fact, I would provide you with your own trial lens kit, and you can "prescribe" a minus for yourself if you love it that much.
But I use a trial-lens kit as a scientific measurement tool, not as a "prescription device".
The primate eye data (response to plus and minus lens) makes the issue final (on a SCIENTIFIC LEVEL) for me.
For all others -- well they are just confused -- at best.

Remember: it's easy to claim your 'preventive methods" work when the data shows that 85% of the kids weren't getting myopic, anyway.
Then, you just have to insult the remaining 15% -- saying they were lazy, stupid, ignorant, or immature (what he's saying about his dear niece, Joy Benson, apparently).
Quite a scam, eh?

If that were the case, there would be many more dead AIDS victims. The way understand it, AIDS went from being an almost certain death to a nasty but treatable disease. That is because an intricate drug taking regime appears to work.
Progressive myopia may not be as nasty as AIDS but it may need at least as intricate a process for curing. That does not mean dumping the idea.
I think the main scientific idea to be decided first is: Does using negative correction lead to increased positive refractive error. After all the controversy here, I still do not know the opinions of major posters here. For example, does Mike Tyner merely deny the benefit of Otis's proposed treatment but admit to negative lens contribution to progressive myopia?
I believe negative lens correction does accelerate positive refractive error. At this point, I think that experiment has already verified that. I am not ready to seek the cure yet based upon known science. The Soon curve brought up by Otis seems to be a good vehicle for scientific testing without harming participants any more than they are being harmed by "best practice."

Test question, very relevant to anyone with a license: Why are the benefits of wearing plus so hard to measure?
Why are the Oakley-Young results so hard to replicate?
Why is the accellerating effect of glasses so hard to measure?

I am not asserting the Soon curve as fact, I do assert that if it can be shown to be fact by means of competent experimental replication, then we will have a basis of how to intervene to limit progression of myopia.
Let me ask the following question for which I want a yes or no answer, Does the preponderance of scientific evidence show that negative corrective lens use accelerates progression of myopia? I want to leave talk of cure for another time.
My interest in the Soon curve is that it is a very specific statement of fact that is subject to statistical testing. I am willing to start out with it being considered it unlikely for many reasons including possible scientific fraud. That does not diminish the promise that taking the data to support or refute it will lead to useful scientific knowledge.

To the extent that you're interested and/or physically able, I'd recommend this as a good source of basic info on the entire debate:
http://www.nap.edu/openbook.php?isbn=0309040817
Also, take a look at this study -- one of the ones that solidified a few elements of my "protocol."
http://health.groups.yahoo.com/group/i-see/message/17660
Even if you DID torture your macaque/baby chicken/shrew, with unnecessary glasses ... you just have to let the things run around outside without them -- as kids/people SHOULD do, regardless -- and the damage is undone.
These are the exact issues -- hugely relevant issues -- that Otis actively ignores.

That's a rarity, if not unprecedented.
I've known numerous people in my life who wore minus lenses since childhood, and -- despite early progression in their myopia -- their Rx stabilized and remained unchanged (+/- 0.25d either way, depending on who did the refraction) for decades -- all the way through presbyopia.
My wife and my brother are two such examples. Both wore their glasses for all waking hours. Each wore them all the way through undergrad. My wife wore hers all the way through grad school.
They're each roughly -3.25d, though my wife finally DID have PRK (and couldn't be more thrilled with her result).
I've researched eyes and vision for decades. I've never seen anything that would lead me to believe that minus lenses accelerate myopia progression.
That said -- and I'll repeat myself, here -- my "protocol" offers tested and/or perfectly logical solutions to EVERY SINGLE POSSIBLE POSSIBLE PROBLEM that the likes of Otis contends minus lenses might cause.
And ... again ... as somebody who has suffered from accommodative spasm issues for decades, I know a great deal about this subject.
The sort of myopia that Otis (and other advocates of Natural Vision Improvement who are NOT insane (as he is)) seeks to forestall is accommodative myopia (a/k/a pseudomyopia).
I've never seen any evidence that pseudomyopia causes axial-length myopia. Repeating myself yet again: if it truly happens, then it surely should have happened in my case.
It didn't.
I forgot which OD first proposed the analogy, but ... it's perfect: blaming the minus lens for myopia progression is like blaming that first barber for a child's hair continuing to grow....
The current opinion of mainstream vision research is basically this: there is no evidence that appropriate correction or over-correction of myopia hastens myopia progression.
There has been at least ONE credible study that showed that UNDER- CORRECTION of myopia (in effect, what Otis advocates) DOES ACCELERATE myopic progression.
That's MY "yes or no" answer to your question ;-)

BUT ... I genuinely think it WOULD be worth your while to take a look at that National Academy of Sciences book. It is an extremely well- written and thoroughgoing treatment of the subject of myopia progression and prevalence, including a broad meta-analysis of existing studies.
BTW: I'm VERY glad that you remain conscious of the BAK issues. It seems to me that the practice, among prescribing eye docs, is slowly changing.
Otis - 24 Jun 2009 19:56 GMT Dear Bill,
Thanks for your thougtful review.
But some phrases require SOME clarification.
Remember, medicine is not like the "hard" sciences, math, engineering, control-system design.
Medicine, and the minus lens grew out of the fact that 400 years ago, some people found that a minus lens "sharpened" their vision, after they induced a negative STATE in their eyes.
They never asked "why", just started wearing the "obvious" minus lens. There is no real "hard" science behind this process, and the real justification is that it "works" on everyone.
But let me attempt to clarify you questions:
Bill> Let me ask the following question for which I want a yes or no answer,
> Does the preponderance of scientific evidence show that negative > corrective lens use accelerates progression of myopia? Otis> This depends TOTALLY on WHO is doing the judging. The majority- opinion medical people INSIST THAT A MINUS HAS NO EFFECT ON THE EYE'S REFRACTIVE STATE. The second-opinion people insist that it does. The appeal to "fact" and "science" has NO EFFECT ON EITHER GROUP. Asking for a consensus, simply drives these two groups further appart. The simple answer is that the majority-opinion group says "NO", and the second-opinion group says "YES".
Bill> I want to leave talk of cure for another time
Otis> Fine! Then you must rely on this bifurcation of opinion -- because each group is going to cite their own studies to make their claim.
Otis> But I personally I take Soon's "curves" VERY SERIOUSLY, and suggest that that first "minus lens step" be reviewed very seriously -- as the preventive second-opinion.
Engineering best,
Otis

If it did, doctors would be required to warn patients of potential side effects.
So, how many pediatric ophthalmologists write prescriptions for myopia and warn patients to remove glasses for close work? None I know.
Because THEIR literature says reading with or without glasses or bifocals or "plus" makes so little difference you can't support one recommendation over another. Br J Ophthalmol. 1989 July; 73(7): 547-551
How many US optometrists warn myopes to remove -2.00 glasses? A few are left, but they tend to be older.
Outside the US, you often don't know what "optometrist" actually means. There is evidence that it means "flake" in some places.
We tend to lose perspective in this little corner of the Internet... like this question hasn't been pounded to death with evidence-based practices and policies, at the FDA, FTC and in elementary schools and universities all over the globe.
There's your preponderance.
Donald Rehm recently petitioned the FDA to require myopia warnings on spectacle lenses. What does it mean if they refuse?
Me personally, I've only ever said to parents that they shouldn't beat themselves or their kids up about it. I think of Otis every time I say that.

I thought that I worded the question in such a way that a Yes/No answer would the only allowable answer. A maybe or it depends logically requires a NO.
My gripe is not with the answer but with a fallacy invoked. I get the answer No comes from requiring the desired result rather than from experimental determination.

If so, I would have been told about the BAK in some Naphazoline eye drop recently prescribed to me. to help itchy eyes. I had even mentioned the problems I had run into from BAK.

In practice, I now believe that I would NOT be warned even if my premise were true. It seems like another "We have always done it that way."
Is anyone else willing to give me a Yes/No answer?

Doctors don't warn myopes BECAUSE the preponderance of published studies do not show that wearing glasses accellerates myopia.

What if they quit using BAK 20 years ago and now Otis wants to bring it back?
Optometrists used to prescribe bifocals and reading lenses and hygeine and exercises in order to "control" myopia.
Why did they quit?

Yes, Mike Tyner says that "most" studies don't show that the eye goes down with an applied minus lens. That is Tyner's selective CHOICE as to WHICH study he "believes", or it is in fact his OPINION.
The issue is that SOME studies DO SHOW that the minus does produce the SECONDARY response, of accellerating the DOWN RATE. But let us just be honest. The people who understand this, are called second-OPINION health professionals.
In this context there can be NO "yes" or "no" answer.
Prevention best,
Otis

Your phrasing clearly indicates causality. I'd be interested in seeing whether you can reference a credible study that backs up your assertion.
Just a little heads-up, incidentally: Oakley-Young doesn't establish causality, and is NOT randomized. Its subjects were near-point esophores.
I presume you know the difference, right?
Thanks!

The preponderance of evidence shows that the use of negative lenses to correct existing myopia does not accelerate the progression of myopia. There is little human evidence of course but the animal evidence is clear: animals who wear minus to correct existing myopia do not progress.
The next time Otis claims that minus lenses cause "stair case" myopia, ask him for evidence for that statement. The Soon graph is not evidence, it is a speculation of what might happen if minus lenses cause progressive myopia, not a graph based on any actual measurements. The Soon graph is as valid as one published by the Flat Earth Society showing how far you could walk in various directions before falling off.

At THAT time, nearly EVERYBODY believed that the Earth was flat.
In the extant case, however, only a few whack-jobs, True Believers, and those seeking financial gain subscribe to the "stair-case myopia" theory.
