drfrank21@hotmail.com - 17 Feb 2005 03:46 GMT Dear Fellow Friends,
I have friends in both electrical and chemical engineering.
They are doing to best that they can. But some get so fixated that they are unwilling and unable to examine facts logically.
While I might "technically" disagree with them about the analysis in their fields, I respect that in many, perhaps most, cases they do what they were taught to do. And that's to ignore any findings or facts that do not correlate to their way of thinking.
So -- as always -- please respect the man/woman or robot -- even though you think a "second opinion" should be more completely developed and implemented. Who knows, even your next door neighbor may be an engineer- so accept them as who they are.
Best to everyone

This is past insulting and into laughable ignorance. Engineers are taught to _NEVER_ ignore data, even if there is no apparent explanation. But anyone, in any field, can get fixated and carried away with a pet theory. But this is a human failing. Not part of the curriculum!

otisbrown@pa.net - 17 Feb 2005 04:40 GMT Dear Friends, Subject: Hand extended in friendship.
Certainly when new ideas (concering prevention) there will be a certain "anger" in those who are continuing the minus-lens method of the last 400 years.
You would be wise to look at the "second opinion" and consider it -- as developed by Steve Leung OD.
You might be able to help you child maintain clear distant vision through the school years.
www.chinamyopia.org
Remember this -- before your child gets that first strong minus lens.
There is an agreement that the situation of nearsighedness is ONLY PREVENTABLE in its first stage.
These ODs will never discuss this possibility with you.
Think for yourself.
Berst,
Otis

[quoted text clipped - 3 lines] > "anger" in those who are continuing > the minus-lens method of the last 400 years. Anger? Why? I for one, and certainly most others I know, will be glad to offer your preventive method if it is proven to work, But............
1) You don't answere our queations. 2) You say that there are many OD's offering the preventive method, yet I only see the name of Steve Leung. (By the way does Steve have an OD or does he have a Profesional Diploma In Optometry, or both). I still can't understand why Steve himself does not appear on the NG to defend the "second opinion" 3) You Don't seem to understand what we are saying and therefore answere our questions with the same (repeated many many times) ideas. 4) You challenge the opinion of others by using something I call "Otis Logic" And so on
I hope you understand that by so doing you have lost credibility. As a scientist you must know how important this is if you want to influence the profession or the public at large.
The very basis of your theory is the control of accomodation. You have said that the minus lens brings the world closer to the observer therefore stimulating even more accomodation causing stair-case myopia. (Not your exact words but this is what is understood by me. Please correct me if I am wrong)
Now answere this:-
a) A -10.00 diopter myope wearing a pair of spectacles at a vertex distance of 13 mm. b) The same subject as (a) but this time wearing an appropriate contact lens c) An emetrope wearing nothing.
a,b and c are all looking at an object 30 cm. away.
Who needs to use the greatest accomodative effort (a) (b) or (c) Who needs to accomodate the least. Why?
Roland J. Izaac
P.S. I heard something about Steve being brought up by the licencing board for offering the plus lens. Is this true?

I was hoping this certain individual would actually look in the mirror and admit that his post was just another slam. But it went over his head (as always).
Robert, if you're an engineer, I'm sure you're very competent and capable such as the optometrists here in this group.

Had you wanted to make it clearer, you could have replied to his post, just changing the Subject. Threading works.
I don't much like Rishi or Otis, but I'm still waiting for an explanation of dramatic myopia increase when populations increase near-work.

Sibirer - 17 Feb 2005 07:34 GMT > Dear Fellow Friends, > [quoted text clipped - 13 lines] > any findings or facts that do not > correlate to their way of thinking. Ignoring properly reproducible findings is completely against everything taught in engineering classes. Ignoring reality can kill people in civil engineering or any other field of engineering. An engineer cannot allow their personal thoughts to interfere with reality. This is an engineers way of thinking. They always want to reinvent the wheel, but they must still abide by physics. Unfortunately, they often need to consult with a pshycologist to make sure it is usable by anyone other than themselves. They rarely do, judging by the poor devices out there.
Sounds like some people have become too caught up in politics (the process of making the world correspond to your thinking,) to remember their training! It's too easy and happens all of the time.

***** OTIS WARNING *****
This posting is an automatic reply to any sci.med.vision newsgroup thread that is receiving comments from a person named "Otis", "Otis Brown", "otisbrown@pa.net" or "Otis, Engineer".
Otis is not an expert in any field of vision. His medical and eyecare training is nil. He is a proponent of a myopia prevention technique that is unproven.
Otis continually misquotes people in his posts. He drops the names of doctors whom he falsely claims to be associated with. He has been caught in out-and-out lies. He has given people incorrect medical advise. Sadly, his behavior suggests he may have psychological problems that compel him to argue against people just for the sake of causing an argument.
Otis is what is known in internet newsgroup lingo as a "troll". Do not reply to his postings-- it just takes up bandwidth and storage space that should be reserved for meaningful topics. It also just fulfils his sick psychological needs.
No one means to suppress the honest opinions of others. This message is only meant to forewarn newcomers who might misconstrue Otis as a trained eyecare expert. Those of us who have been here for awhile know Otis oh too well!
For anyone who is interested in understanding the true state of scientific/medical research on myopia prevention, I offer the following link: http://annals.edu.sg/pdf200401/V33N1p4.pdf. If you are truly interested in Otis' theories of myopia prevention then visit his favorite websites www.i-see.org and www.chinamyopia.com.
If you have other topics you wish to discuss, there are experts here who will usually help you. Don't waste your time with Otis.
Please see the weekly posting "welcome to sci.med.vision", which usually appears on Mondays, for a guide regarding this newsgroup and for information on how to filter out Otis' posts so that you may be able to participate in worthwhile discussions in this forum.
otisbrown@pa.net - 17 Feb 2005 16:47 GMT Dear Carl,
I have good friends in optometry. They respect me -- and I respect them -- despite the effort by SOME ODs on this NG to destroy the "second-opnion" concept.
I separate engineering-science from "medicine".
The "medical" person must have an "immediate solution", which largly consists of a minus-lens. The public (with rare exceptiongs) expects EXCLUSIVLY that quick-fix with the minus lens. I describe that as a "medical process", that can not be "broken" by reason, logic, common-sense or engineering-sciences.
When you realize this -- you understand the need to separate pure-science from "medicine".
The USA has a problem with obese children. In terms of engineering-science (objective, factual truth) this issue is simple:
1. Conversiation of energy. 2. Calories into child less than child "burns". 3. Child loses weight.
The enginering-scientific solution is absolutly clear.
Then why does "medicine" struggle with the issue?
Because the great mass of people love to over-eat.
The "engineer" knows the correct solution -- but can never "implement" it.
The "medical" person must deal with the CONSEQUENCES of this "over-eating". Very few in medicine will explain the engineering-scientific solution -- because they know the "public" will not listen.
That is the difference between an "engineering" approach to understanding and representing the "fact" concerning the dynamic behavior of the natural eye -- and the means that "medicine" uses to deal with the great mass of the public that walks in off the street.
The problem develops when I make "clean" statements about the behavior of a population of natural eyes (in terms of measured refractive-state.)
This is an engineerin test to determine if the natural eye is dynamic -- and has NOTHING to do with "defect" at all. The natural eye can and does have postive and negative refractive states.
Part of this effort is to get you (and others) to think in an abstract way about the natural eyes behavior. Truly and "intellectual" enterprise -- dispite the "slams" posted by RM who either does not "like" or even understand the concept.
This is an "open" forum, and I alway hope to have a pleasant coversation -- where we grown in wisdom and knowledge.
Perhaps in presenting scientific knowlege I have hit a "nerve" in RM. Finsal scientifc truth does seem to hurt him -- for some reason.
Best,
Otis Engineer

There is no mandate that a "medical" person have an "immediate solution." For example, vision therapy does not promise a quick-fix, nor does chemotherapy.
Your ideas do not even rise to the level of bad medicine, let alone pure science.

Repeating Rifle - 18 Feb 2005 01:49 GMT > I have friends in both electrical and > chemical engineering. [quoted text clipped - 3 lines] > are unwilling and unable to > examine facts logically. I am a registered electrical professional engineer in California. Engineers often have to work on projects with limited information. The laws of California allow that to be done if it is done competently. Engineering is often based upon physical science but is not limited to that. For example, designing and buiding a good night vision system requires knowledge of visual science as well as of electronics. California law does not allow practice outside your field of competency. You are held responsible for knowing your limitations.
Medicine is also an engineering art. Physicians always are working with limited information. Although steeped in biological science, a physician has to know other stuff as well. I would be upset having a cardiologist who does not have a basic knowledge of fluid mechanics.
That said, many "engineers" are not registered engineers. A graduate engineer is not an engineer in the eyes of the law. They are able to practice engineering because of corporate exemption. Similary, physicians cannot practice legally without being registered (licensed), no matter how much post graduate education they have.
When I post my opinion on the newsgroup, I try to be correct (or at least flippant). I usually state that I am not a vision professional and that my advice is worth what it costs. I do understand optics although not the nuances of optometry and ophthalmology.

otisbrown@pa.net - 18 Feb 2005 04:00 GMT Dear Bill,
Well said.
For personal reasons, I decided to explore the concept of the "dynamic eye" -- spcifically to avoid all the "hoopla" you see posted against the concept.
>From this work, I deduced that a negative refractive state of the natural eye could be prevented by intelligent and forceful use of a plus -- at the threshold.
I did "wonder" what the ODs "thought" about the concept -- and the extent that they used it. Since I appreciated how difficult it would be to use properly -- I thought that some ODs would have an "intuitive" sense of the eye -- and would use the plus "correctly" on their own children.
In effect, some ODs have in fact reached that conclusion -- and are now using the plus on their own children. This effectively means long-term use of a strong plus -- for the child on the "threshold". It also means that the OD is going to be making that judgment for his own child.
The work of Dr. Francis Young and Dr. Kenneth Oakley MD, demonstrated that a properly used plus (where the child actually looks THROUGH THE PLUS) was effective in stopping the "down" movement of the eye.
With I that I have stated here, I do agree that "agressive" use of the plus -- as Dr. Stirling Colgate has done it -- is indeed difficult since it takes a person of considerable motivation to do it correctly -- and successfully.
Since that is the case -- it clearly can not be "prescribed" -- and for that reason I suggest that the result must rest with the person doing the work.
Further, for "legal reasons" -- as you stated -- the "medical" person simply can not "prescribe" anything like this. There is no solution in 15 minuntes in an office -- and we may as well stop looking for a "medical" solution.
So, except for RM, who does not understand the "abstract" analysis of the behavior of the natural eye -- I think we could develop a "preventive" method. But the person himself would have to make the judgment at the threshold -- before any action was taken.
Since I was well-aware of RM's attitude -- and its effect, I talked to my sister's children about this problem.
I stated that they HAD TO USE THE PLUS, and personally verify that they ALWAYS passed the required legal visual-acuity test -- or they would wind up with a strong minus lens "prescibed" by this RM.
That got their attention. As a result, they systematically use a STRONG plus, and when they saw they were losing their distant vision, they simply did what Dr. Colgate did -- got a plus and persistently used it to clear their eye-chart vision.
But this was indeed a life-time commitment to the "correct use" of the plus. This type of work can NEVER be reduced to a "prescription in 15 minutes", and it is never my intention to even suggest that is possible.
But by technical analysis of the natural eye's behavior it is possible to "see" that it is possible.
The issue does come down to the meaning of SCIENTIFIC proof that the natural eye is dyanamic, rather than "medical" proof where you attempt to come up with an impressive "quick fix" which "works" with out the "understand" of the person involved with it.
We should endeavor to keep a scientifc "open mind" on representing the natural eye as a dynamic system, where we test on an "input" versus "output" basis -- and end the word "defect" when talking about the natural eye in this manner.
Best,
Otis Engineer

You THINK it might work?
Ah, but you think it's a new idea, don't you?
Show us something that works. The Lancet and NEJM and Scientific American will be interested.

Intuition is a wonderful thing. I'm sure that's how many people develop a scientific hypothesis. But after you get a hypothesis, it needs to be tested. Your concept of the plus lens sounds intuitively correct. You don't get to be an Olympic athlete by resting your muscles. Why shouldn't eye exercises help? But the ODs on this group say that the testing has been done, and doesn't support the hypothesis. Furthermore, we know that exercising our legs doesn't make them shorter or longer. Those who know something about the eye say that it reacts more like legs than muscles.
There are lots of things that are intuitively obvious. Drop something heavy and something light, and the heavy thing drops faster. Gravity must pull harder on heavy things.
Walk outside and look at the earth. There are hills and valleys, but it's basically flat.
Walk outside at different times of the day, and you can see the sun circling around the earth.
Look around while driving, and you'll see (at least in the US) pickup trucks with no tailgate. Obviously, if you take off the tailgate, you'll lower the wind resistance.
What do all of the above have in common? They're wrong! They have been tested, and shown to be false.
