acemanvx@yahoo.com - 18 Dec 2005 14:01 GMT This is something that has caught my interest! I have been looking into it for some time but now im really serious about it. With all the negative on laser surgury about its risks and complications, plus the fact im not your "perfect" candidate, lasik is definately not for me. I have researched this throughtly and conclude it wont work well for me. Its permaent too so whatever you get, its forever better or worse. I will save the lecture on lasik here as this isnt really a lasik BB. My topic in question is Ortho-K! Anyone here have experience or knowlege?
The main concern is the risks of complications due to overnight wear of the RGP orthoK lenses. Netherless I and most others believe its considerabily less risky than lasik. Plus if orthoK doesnt work out, its reversable, lasik your stuck with it and whatever vision it gives you. One optometrist says hes never gotten more than -4 diopter correction in anyone with orthoK. This is not an issue for me because I have only -5(left) -4.5(right) with little, if any regular astigmastim. Plus due to my presbyopia, its beneficial I leave a little myopia so at least I can see the computer clearly without reading glasses and only need reading glasses to read fine print. I may have pseudomyopia so ill only want to correct my cycoplegic refraction and exercise my eyes to resolve the pseudomyopia. I may get another cycoplegic refraction after orthoK to ensure im not overcorrected, this will rule out any latent hyperopia accomodated. I have a relistic goal of orthoK, see well enough to be in focus at 2/3 meter which will let me see this computer monitor clearly sans glasses. I wont need glasses around the house for the matter. In fact im wearing -3.25 glasses so ill be happy to achieve this much correction from orthoK then ill only sometimes need distance glasses.
I am worried about my huge pupils and have been told this may complicate orthoK ah well as long as the night vision isnt too bad, im sticking with it. Its temporary so I can cease using orthoK if im not satisfied for any reason. I need to get an appointment for orthoK and see what the expert optometrist says. If he says I have litle or no chance of it working, ill leave things be. If he says I have a reasonable chance, by all means ill go for it! Itll probably cost like $1500 but ill try to find a doctor with a partial refund policy, one of them will give all but $300 back if you turn in the orthoK lenses within a month(or was it three?)

acemanvx@yahoo.com - 18 Dec 2005 15:34 GMT "Why not give it a try and report back to the group?"
my mom thinks its a gimmic that itll work for an hour then ill regress, she basically doesnt believe in it, but says if I can show her real experiences here she will change her tune. DrG, can you share some if you know anyone whos done orthoK or better yet, if you perform it yourself? Give a summary. How long do the effects last? How much myopia gets corrected, whats the most myopia youve seen or heard someone get corrected/reduced? Is there any discomfort initially and long term? How does it fare for night vision? Does it change your BCVA for better or worse?
"Ortho-K is expensive, running about $1,000 to $1,600 -- depending on the OD."
Thats still 1/3 to 1/4 the price of controversal lasik, a great bargin compared to lasik. Its also the same price as me getting RGP contacts but I believe ill be much happier with orthoK than rgp contacts. My optometrist warned me dust is the enemy, get any in and your in for a world of pain and must remove the RGP lenses immediately and on the spot. Theres other things I dont like about them. With orthoK I will be almost free of glasses!
"It is mostly effective for refractive states of better than -2 diopters, with perhaps -3 diopters possible."
>From what I read, todays orthoK technology can address less than -3 diopters very easily, this is where low myopia falls. It will greatly reduce the pescription of a moderate myope like me. Different people respond differently but I would think a reduction of -3 diopters should be doable. I may be -4.5 and -5 but some of it is pseudomyopia. I do NOT want to correct more than my axial myopia. I do want to be undercorrected a little so I dont need reading glasses full time. I am not 8 years old anymore and dont have the accomodative amplitude of one. How much myopia should I leave? I am thinking between 1 and 2 diopters, less than -1 and ill need reading glasses full time, more than -2 and my distance vision wont be clear enough. -1.5 is the sweet spot and is actually the undercorrection presbyopes are happiest with. If orthoK addresses 3 diopters, ill be -2 and -1.5, a very small amount of anisometropa and monovision, something I can handle no problem. This is good enough to reduce my dependancy on glasses by more than 75% and only need reading glasses for fine print or getting a closeup look, such as threading a needle.
"The effect does not last. Stop wearing the "retiner" and you go right bact to you previous prescription."
stop wearing glasses and the same problem. I will wear the retainer lense as often as I need to keep the effects. Its more a good thing its not permaent in case it doesnt work out for you. With laser surgury your stuck with it better or worse.
Dr. Leukoma - 18 Dec 2005 15:56 GMT Ace,
You and I have traded posts about this before. I don't really think you are sincere about pursuing orthokeratology, as there is plenty of information available to indicate that you are at the extreme end of the range of correction, if not out of range for this modality. Besides, if you have dry eyes, you shouldn't be sleeping in any kind of contact lens.

"You and I have traded posts about this before."
I know, but do you have any knowlege about the following questions? DrG, can you share some if you know anyone whos done orthoK or better yet, if you perform it yourself? Give a summary. How long do the effects last? How much myopia
gets corrected, whats the most myopia youve seen or heard someone get corrected/reduced? Is there any discomfort initially and long term? How
does it fare for night vision? Does it change your BCVA for better or worse?
"Besides, if you have dry eyes, you shouldn't be sleeping in any kind of contact lens."
I will take a scheimer's test and let the optometrist decide if the dryness of my eyes is mild enough to be OK for orthoK.
"Therefore, why should you care what mummee thinks?"
Because shes going to pay for it? She knows I need vision correction and if she knows orthoK will work then I may get that.
"The last I heard, you were still trying to convince your daddy that you needed a good eye exam."
Yes one that includes a cycoplegic refraction with a potent cycoplegia agent.
"Yes. Yes, you do."
Ok good. Do you have any experience? I have some questions, see above. Tell me everything about orthoK experience, this is what I need to convinece my parents.

acemanvx@yahoo.com - 18 Dec 2005 16:52 GMT I already searched on google and know about orthoK but what me and my parents need is personal orthoK experiences or know people with experiences. We want to push aside the hype and marketing and see how others react to orthoK and if it really delivers. My parents said if orthoK was so good, there would be no point in most people getting laser surgury!

Unless you get a patient list from doctors (which you won't) and call those people directly, what you'll get is what's known as a "self-selecting sample," meaning: the people you'll hear from (if any) are those who had exceptionally positive, or exceptionally negative experiences. This is either end of the bell curve. You won't get the experiences of the masses who are in the middle.
Go see an eye doctor. Find out if you're even a candidate. Refine your question list based on what that eye doctor says, then come back to the computer.

Dr. Leukoma - 18 Dec 2005 17:12 GMT Ace, the first rule of internet bulletin boards is that people report their personal subjective experiences. Someone will post "I hate orthokeratology. The lenses were a pain, my night vision was terrible, and I just got fedup with all the mainencance." Someone else will post "I love orthokeratology. I cannot feel the lenses in my eyes, my vision is excellent, and I am a happy camper."
What kind of parents would be swayed by a post from someone on the internet? Surely, not yours.

acemanvx@yahoo.com - 18 Dec 2005 18:24 GMT "is that people report their personal subjective experiences."
I want to hear all experiences, both good and bad. I will not be swayed by bias. Its perfectly normal to have a bad experience for anything be it glasses, lasik, contacts or something entirely different like buying a certain brand of cookie and it tastes terriable! I want to see how orthoK is for them. I will be able to arrive at a general informed decision.
"What kind of parents would be swayed by a post from someone on the internet? Surely, not yours."
Where it stands, they know nothing about orthoK and think its just a gimmic. I told them everything about it and they said if its as good as I make it out to be, almost everyone would be using orthoK! My mom may even use orthoK herself if it can correct high myopes(which it cant currently and may never be able to due to the nature of excess corneal molding) My sister has shown some interest and even my brother may try it if it works really well for me. Brother doesnt have much dependance on glasses but if orthoK is so easy, hey its free vision improvement! I have some friends that may try orthoK themselves but they too are skeptical, they need testimonals.
"You won't get the experiences of the masses who are in the middle."
oh yea? Theres a few hundred lasik experience reports online, some negetive, some positive, some in between. Ive seen very few orthoK reports, one negetive the the rest positive. I read an article and its appearenly popular in children that are shy of glasses but not old enough for lasik.
"Go see an eye doctor. Find out if you're even a candidate. Refine your question list based on what that eye doctor says, then come back to the computer."
will do, but maybe you guys can think of questions I can use to ask the doc?
"Meanwhile: did you see this?"
Irrevelent, its old tech. Todays orthoK can correct 3 diopters without a problem, even 4 with a more aggressive approach.

Ortho-K is expensive, running about $1,000 to $1,600 -- depending on the OD.
It is mostly effective for refractive states of better than -2 diopters, with perhaps -3 diopters possible.
The effect does not last. Stop wearing the "retiner" and you go right bact to you previous prescription.

Ace has a right to be fully and completely informed of the second opinion at the threshold (i.e., pseudo-myopia).
The most likely result of Ace being provided with this preventive information -- would be that he would reject it. In which case, the stair-case myopia that he developes (as a result of wearing that minus all the time) would be his choice and his responsibility.

Subject: Evading questions not answering them.
I see you have done it yet again! You again attacked me, an not "corrected" the general statements I made about Ortho-K. If you think they are not correct -- then redefine them -- or answer them.
Yes, I expect accurate answers from you concerning the dynamic beahvior of the living eye.
And it is obvious that you are always going to evade them also -- because you hate the implications of the correct and accurate scientific answers.
Let us try again. I stated that Ortho-K can clear vision from about -2 diopters to "normal", and it has been used by pilots for that purpose. Now, do you:
1. Agree?
2. Disagree?
Then I said, that when a pilot stops using the "retainer", his vision tends to return towards -2 diopters. Now, do you:
1. Agree?
2. Disagree?
Now, rather than attacking me, why not provide your own assessment of these answers?
Best,
Otis

acemanvx@yahoo.com - 19 Dec 2005 22:05 GMT So I can only expect to clear -2 diopters of myopia with OrthoK? I could do that in conjuction with clearing pseudomyopia and the -2 reduction due to OrthoK may somewhat reduce my dependancy on glasses which should make it easier to resolve my pseudomyopia as well. I read in vision improvement books including one by Dr. Bates who says glasses are crutches that hinder improvement and often cause stair case myopia. Otis would agree with that too. One of my friends who does vision improvement says its much easier to improve and results come faster if your not wearing glasses. Right now im too "blind" to go without glasses for more than 10 minutes. I am -5 or near that and its a significent amount of myopia.
I am -5(left) -4.5(right) with very slight astigmastim. OrthoK can clear -2 diopters plus my minimal astigmastim. This will put me down to -3(left) and -2.5(right) letting me clear 20/200 without a problem. How long does it take orthoK to clear -2 diopters if the retainer lense is worn nightly? I will countinue to wear my -3.25 computer glasses till they become too strong then ill just forgo glasses.(or as Otis puts it, the evil minus lense!) This is when ill start being able to clear my pseudomyopia and get down further, perhaps to 20/70? 20/50? I will use the plus lense for extended periods of reading or near work to keep my vision sharp and also because my accomodative amplitude isnt too good. I dont drive so I have no DVM obligations to clear 20/40. I wont be needing the minus lense even if I fall a little shy of that. Ill be completely free of the minus lense and will only need the plus lense for prolonged near work as a precaution and to greatly reduce eyestrain and accomodative spasms. Otis never claims to be a doctor. Perhaps hes a scientist or philosopher?
Again to clarify, I am/should be -5 and -4.5. I should get down to -3 and -2.5 or therebouts and easily clear 20/200. Then being able to see well enough to function without the minus lense, I then can keep clearing my vision by resolving my pseudomyopia. I should attain a level of vision that while not perfect 20/20(cant even be corrected to that anyway) or even a bit shy of 20/40, will let me be very functional without the minus lense. Ill be able to see the computer clearly without strain due to my slight residual myopia and only need plus lense for prolonged near work.

We do appreciate your gradually adopting more conventional terms and definitions. "Living eye" is much easier to define than "natural eye."

Speaking for every optometrist, we'd be happy to adopt your cure for myopia if you'll just show us it works. It's been tried and never proven reliable, but maybe you have the secret. How was it you use a Snellen chart to prevent myopia?
> Now, rather than attacking me, why not provide your > own assessment of these answers? OK now we're back to that. No, your answers were right... ortho-K works, but it's temporary, it's limited, and as you love to say, it's expensive. I don't see much point to it, except where glasses are hazardous or inconvenient.

> Best, > [quoted text clipped - 7 lines] > > -MT acemanvx@yahoo.com - 21 Dec 2005 11:42 GMT Otis and anyone is welcome to give me advice. I know many of you arent doctors, some may be patients or know other patients with experience reguarding orthoK. Anything that helps me learn more about orthoK is welcomed! I now know that orthoK is good for correcting -2 diopters(and less) I do hope I can achieve a little more than -2 diopters correction so I can further reduce my dependancy on glasses.
"Dr. Bates published in 1919. His ideas have had eighty-six years to catch fire. We are still wearing contact lenses and eyeglasses."
Theres too many non believers and with all the near work people do, they are just ruining their eyes. Hey 86 years ago there were no computers and almost everyone used their eyes for distance only! Now most people use their eyes for near only! Did you know the percentage of myopes today is MUCH greater than it was in the past?
"As I said, why don't you just *do it* and report back your results. Since clear unaided vision is not your goal, the results should be successful."
Well it helps to learn more about something before jumping in it. Of course I need to also schedule an appointment with an orthoK doctor for an eye exam and questioning. I am guaranteed clear distance vision without glasses and with glasses I should keep my 20/30 BCVA and possibily see like half of the 20/25 line due to much less minification of weaker glasses. I did email an orthoK optometrist who says I definately will be seeing every bit as good as I do now with glasses, or else he can tweak the contact lenses to further improve me. Not only can orthoK not fully correct me, I cant and dont want to be fully corrected because I dont have a high accomodative amplitude. I am not about to trade distance glasses for readers but by keeping some myopia(-5 is too much!) I will greatly improve my distance vision, greatly reduce dependancy on glasses and yet still not need readers.
"Dr. Bates would have been horrified by the idea of contact lenses, since they hadn't been invented yet at the time he did his phony "research"."
LOL I hope no one mentions lasik to "him" as for his research, hes fully qualified being a doctor and optometrist so he knew everything about the eyes. Yes modern optometrists do disagree with some of his points. I think he was claiming you can improve all imperfect vision to 20/20. You cant if you have too much myopia. Hyperopia can be cleared if done early in childhood while your still undergoing emmetropization. Almost everyone starts out as a hyperope, this is normal and glasses arent needed unless your a high hyperope than only get glasses strong enough for clear vision and let the child accomodate the rest.
"No, your answers were right... ortho-K works, but it's temporary, it's limited, and as you love to say, it's expensive. I
don't see much point to it, except where glasses are hazardous or inconvenient."
I will take any improvement in my uncorrected vision. I want to wake up to a clear(er) world, see the digital clock without squinting, wake up and look around my bedroom clear(er) without first reaching for glasses. Id love to shower and swim without so much blur. I have started taking up biking and working out and may do other outdoor activities. Not needing glasses for such activities is quite a convinence. Best of all, I can greatly reduce my dependancy in the evil minus lense and save my eyes from stair-case myopia and also resolve my pseudomyopia.
"Disagree......I have fitted ortho-lenses that "cleared" vision by 4.5D and a friend of mine managed to "clear" a patient by 5.50D It really depends on the e-value"
That is a CRAZY amount of myopia cleared! Actually I read that orthoK is technicially capable of clearing up to -6 diopters, its not relistic and not really possible. Clearing less than -3 diopters(which is considered low myopia) is both possible and relistic. Clearing -3 to -4 diopters becomes tricky and difficult and many dont achieve this much clearing. I may be a -4.5 and -5 but this is my manifast refraction. I could be considerabily less with cycoplegia and I do NOT want to clear more than my cycoplegic refraction because the cycoplegic shows my true axial myopia. Pseudomyopia will resolve on/in itself once I stop wearing the evil minus lenses so much. Not only that, Ive already mentioned why I want to be slightly undercorrected as well. All people over 40 who use the computer alot understands me.
acemanvx@yahoo.com - 21 Dec 2005 12:26 GMT Let me add something important.
"Ortho-k may be a good option if you suffer from dry eyes. It's been found that this condition is sometimes worsened by LASIK."
My dry eyes isnt bad, id say mild. I still make tears but they get dry at times if im in front of the computer alot or if im tired. Sometimes when I wake in the morning my eyes are a little dry for a short time. Lasik would make dry eyes worse as they said so thats another advantage of orthoK and why im interested in it :) I can reduce my myopia from -5 and -4.5 to -3 and -2.5(orthoK clears about 2 diopters) then I can further reduce it by resolving my pseudomyopia.

All people > over 40 who use the computer alot understands me. I think I can see your future. Although RGP lenses offer the only hope of correcting you to 20/20, you will not pursue them because of lens intolerance. This is one of the reasons you will not pursue orthokeratology. The other reason is that your parents won't shell out the money on any treatment that isn't permanent and cannot fully correct your myopia, and that you will probably give up on anyway. Insofar as eye exercises, Bates, and other nonsense...I guess if you've got the time on your hands it won't hurt. Of course, it won't help much, either.
Also, from your posts on other boards, I see that you have become anti-refractive surgery. Which means that you will continue to wear eyeglasses into the foreseeable future, unless of course you decide to pursue the only realistic option open to you which is getting fitted for one of the newer silicone-hydrogel soft lenses....or wait until the new hybrid SynergEyes lens is available in your area.
Best of luck.

Once wavefront tech takes off, I have a 99.9% chance of getting 20/10 or better if my retinas capable of it. Theres talk of wavefront glasses and contacts. Right now yes its true RGP contacts give the best possible vision. Thanks for mentioning SynergEyes lenses! I read they are RGP in the center embedded in soft contact. Those with large pupils may not like them at night and in low light due to the small RGP optical zone. I dont know how much a problem dust is for those but for real RGP contacts dust is your worst enemy. Get a tiny spec in your eyes, they will get trapped under the contact and really hurt! For this reason, orthoK is definately more apealable. Doesnt orthoK provide good vision when your still wearing the retainer lense? Doesnt it work as well as an RGP lense? Yes im intolerant to soft contacts but I am not ruling out orthoK. Many people used orthoK successfuly despite not liking soft contacts.
Well im not quite anti lasik, it seems OK for those really desperate to redude/rid themselves of glasses at the expense of usually worse vision. Its great for those who arent picky and not needing glasses(for the time being) is more important than the best possible vision. Many people are perfectly happy to get 20/30 or even 20/40 after lasik when they were equal or better with glasses/contacts. Residual refractive error and high order aberrations are responsable for this. Lasik has other risks like dry eyes and irritation too. I think as wavefront technology matures in glasses/contacts lasik will lose popularity as most people will still need glasses after lasik to get really sharp vision anyway. Even now a good number of people still wear glasses part time after lasik. You yourself would have been farsighted and in bifocals if you got lasik. Your currently -3.25 and take your glasses off to read and can be corrected to 20/15? which is just amazing!!!!!!!!!!

OK isn't for people who are unconcerned about their vision. It is for people who want good vision.
For christ sake dickhead, learn about what you speak of. OK is a great treaiment for myopes. It is not the alternative to Lasik, as Lasik is not the alternative to glasses. It is simply another means of correction, admittedly a brilliant one. As with Lasik, all appropriate measures need to be taken to ensure that the right candidates are selected.

otisbrown@pa.net - 21 Dec 2005 14:26 GMT Dear Ace,
Subject: These sci.med.vision OD will ALWAYS be majority-opinion "selective" in the studies they cite.
Some thoughts on majority-opinion OD bias.
Since there is no "arguing" with these ODs and they are totally blind about the proven dynamic behavior of the natural eye, I would suggest recognizing the type of "bias" that they represents.
Myself, and other ODs will report the Oakley-Young study, that was better organized and controlled, that demonstrated that a strong-plus, used systematically has the effect of stopping refractive movement in a negative direction. (Than the so-called "Shotwell" study.)
The "plus" group went down at 0.025 diopters (virtually zero) while the full-minus went down at a rate of -0.53 diopters per year.
So rather than attempting to deal with these ODs' intense bias, the better idea is to simply state the second-opinion, and the basis for it.
But the real "test" of an optometrist in reviewing these type of studies, is the judgment of a parent who has HIS OWN CHILD at a refractive state of zero diopters.
What to do?
Given the he can only "control" his own child, then the ONLY prevention he can conduct is to put his own child in a strong plus. This is the real "measure" of a competent "second opinion".
This is of course what Steve Leung is doing with his own five year-old daughter.
We can "learn" from this -- or ignore it. But at least you should be aware of this type of second-opinion judgment.
Best,
Otis

Subject: Understanding the SCIENTIFIC BASIS for the preventive second-opinion
Dear Prevention minded friends,
Subject: Second-opinion on preventing negative refractive states.
I suggest that there is a profound difference concerning "pure science" and "pure medicine". And I suggest the difference is this:
Medicine: Must deal with a great mass of people walking in off the street. There might be some "intelligent" people but that can never be the assumption of the medical doctor. The result is that we get "canned" procedures that "work" instantly. I consider that people in this profession have no choice but to conduct that kind of work -- and I would do the same thing IN THEIR PROFESSION. That would not make it "right" but I do understand them -- and what they are doing.
Science: Must "step back" from that situation, and think about the behavior of the natural eye as a dynamic system. Engineers and scientists simply do not deal with children, nor with others that do not understand the need to work on prevention with the plus.
But when you ask very fundament questions about whether a population of eyes (primates) are dynamic, you get the "second-opinion" answer, that POTENTIALLY a negative refractive status could be prevented -- before the minus lens is applied.
I believe that pure science (i.e., the SCIENTIFIC -- not medical -- experiments proves that point.) But that is the nature of our arguments. Many concepts in science simply can never be reduced to "medicine" and we should understand that truth.
I enjoyed your write-up about pure science, and the majority-opinion "habit" of tossing science out the window when a concept (like the dynamic eye) can not produce a quick-fix in 15 minutes. That seems to be the only criteria for the "public" and the majority opinion OD. Maybe they were "made" for each other.
But that is how I separate "medical issues" from scientific concepts and experimental and objective testing.
But that is why it took a scientist like Dr. Stirling Colgate to do the "work" correctly with the plus and clear his vision from 20/70 to 20/20.
His statements are confirmed by direct experiments with the primate eye, again on a pure-scientific (not medical) level.
Use the term "refractive state" where the natural eye can have positive and negative refractive status (as a dynamic device) and this situation becomes much clearer.
Best,
Otis

otisbrown@pa.net - 21 Dec 2005 15:59 GMT Dear Ace,
I value your intelligence. I believe that if you and your parents had been offered "prevention" with the plus -- and you had the motivation for it -- your vision would now be better-than 20/40.
In my opinion, the living eye will go "down" when you place a minus lens on it. This has been proven on a scientific level (but not "medical" level.) That means that great "caution" should be used in "prescribing a minus" in my opinion.
Here is "Steve" a man who was "myopic", but decided to make agressive use of the plus -- and clear to PASS the DMV level test.
As always, enjoy our pleasant discussions about the proven dynamic quality of the natural primate eye.
Best,
Otis

Newbie seeking help
Hi,
I read as much as I can in the last 2 days about preventing nearsightedness.
Let me tell you my situation. I started wearing glasses at the age of 13. At 28 (now 38) I started wearing contacts lens. For many years I looked for a "cure" but didn't find any. My last test shows that my power is 275 for both eyes (that's how they tell me) and it has been pretty much stable for the last few years. I still have faith that I can have perfect sight without minus glasses or contact lens.
I just got a +1.5 lens for me to start using while I'm using computers. I work a lot with my computers.
My questions is. Since it is dangerous for me to drive without glasses or contact lens. What do you suggest for me now, a lower powered minus glasses or contact lens. If yes what power do you suggest!
I'm planning to start today using +1.5 lens & try to get comfortable with it.
Wish me luck.
Rgds, Steve
P/S - I've printed the eye charts, will stick it today & check out where I stand
__________________________
Dear Steve,
After a great deal of research, I discovered that SOME ODs know what a total disaster that minus lens is. They call it "poison glasses for children." My issue is this -- why not TELL US ABOUT THIS BEFORE THEY PUT THAT FIRST MINUS LENS ON US?
Tragically, they keep their mouth shut -- and will not say squat. Nearsightedness is preventable in that first stage, and I would GLADLY PAY the OD for his information and time -- even if I had to take TOTAL responsibility and do ALL THE WORK MYSELF -- including monitoring my "clearing" on my own eye chart.
[This is my "rant" for today. That being said, the next step is asking about what you "want" in terms of vision clearing.]
I would never use the term "perfect" -- because no eyes are perfect.
I would look for a goal of always passing the DMV (1.8 cm at 6 meters) as a reasonable attainable goal.
I would start by reading your own eye chart.
In fact this is very easy. Just click on www.myopiafree.com
and then eyechart 2 (lower right)
and enter 1 inch and 10 feet, and read the eye chart on your monitor at 10 feet.
I would guess you can read the 20/200 line.
Let us know.
Best,
Otis

Dear Otis,
I tried the test I can see at 20/200 but very blur. By saying "perfect" I meant 20/20 vision, this is what I want ( I know some people reading this might be laughing, no problem, if only they know what true 20/20 vision means to me, oh well...). If I've known this when I was 13 yrs old , I don't have to go thru this now, but life is a lesson and anything is possible is my firm belief.
Otis , please tell me what I can do next. I believe my case can be conquered if you guide me how to approach this matter.
BTW, I work in an office mostly dealing with computers at work & home...and of course I also drive quite a bit everyday.
If you require any other info, please let me know.
Thanks a million, Steve

Otis> The accepted standard for reading a "line" is that you read 1/2 the letters correctly.
For purpose of consistency, please report your Snellen that way.
You said you read all the letters on the 20/40 line.
I would suspect you are reading letters on the 20/30 line. If you read 1/2 the letters, the say you pass the 20/30 line.
This is just for "consistency" with the commercial standard.

Dear Steve,
I personally consider that anyone with better-that 20/40 vision -- has a WONDERFUL SUCCESS! That is my "standard". Vision above that is just great.
The DMV "gave up" on 20/20 as being an "excessive" requirement, and would not require a minus lens until vision less than 20/40. I believe that is a reasonable policy.
Also, you reported -3.0 diopters and less-than 20/200, four months ago.
People with less than 20/200 vision are classed as "legally blind". So if you had lost your glasses then -- you would have been legally blind!
I know that is not quite the case -- but you have made a PROFOUND improvement.
Keep up the good work!
Getting to 20/20 is however a very slow process. (Try tennis and football -- or go the beach, sail, get OUT!) When working to "better" 20/40, that seems to "help" most of all.
Best,
Otis
___________________________________
Dear Otis,
First of all I would like to thank you from the bottom of my heart for your strong dedication to guide others to improve their eye sight. Not everyone has that kind of passion or time to do that.
I will definitely update my progress as times goes by. My personal challenge(altho a little tough) is to "compete" with my niece who has a 20/10 vision and during bright days she has 20/8 vision. Now, that is what I call great eyesight. I even read some having a 20/4 vision...awesome.
With a little a bit of innovation & persistence, most people can achieve what they desire. To me it is important not to have a " mental block". If you say you can , chances are you can. If you say you can't , chances are you can't. So to me, my mental outlook is very important on most outcomes in my life. I only wished that I got to know this new found knowledge much earlier, anyway better late than never
Cheers, Steve
P/S - FYI, I just got (about 2 weeks ago) a pair of +1.5 lens for my niece for her nearwork. I like to "preserve" her good eyesight. Oh yes! I definitely know what to do for my daughter as well when she is 6-7 years old( I can see that she has a little poor eyesight, she's 4+ now). As for my wife, she has glasses of - 0.50 & -1.00 on the other eye( thankfully she never used glasses much, so it stayed that way)and can read 20/40 line before using plus lens. In less then 3 months with irregular use of +1.5 lens (initially +1.0 lens)....now she can read 1/2 of 20/15 line...........I'm so happy for her .
I have another niece who has -7.0 prescription but unfortunately she is not motivated to improve her vision, so I can't do much for her.

Dear Steve,
Thanks for your kind statements.
You would not believe the hostility I get when I suggest this "preventive" alternative. Most people act as though I spit in their face. That is how bad it is. These people do not get a "second" offer of prevention with the plus.
I am convinced that any child, at age 5, who has 20/20 (and a positive refractive state) could keep their vision clear through high school and college. But it does take commitment and work.
Most people go running to an OD, who tells them, "Oh, we heard about that -- it does not work. Don't bother with it." And then the kid gets an over-prescribed minus -- and "loves" it.
Only much later, after he develops "stair-case" myopia from the minus, does he "wake up" and realize that his vision has been destroyed -- for life.
I think you have been very lucky. If your refractive status gets beyond -3 diopters, "clearing" becomes very difficult.
But obviously, why should ANYONE ALLOW IT TO GET THAT BAD?
I think we are ALL OWED A DISCUSSION OF THIS ISSUE BY ANY TRUE-PROFESSIONAL WHO DEALS WITH THE PUBLIC. (But that is my "rant.")
I am convinced that only an "educated" parent can help their own child. And now you can do that. With guidance and support from you (and ODs like Steve Leung) eventually others will "get the idea") and that will be the "preventive" future for your children.
Best of luck,
Otis
================
From Steve: (20/200 to 20/30)
Hi everyone,
Just like to add my view.
Initially when I first found out this forum, I was very excited...an opportunity to improve my vision. This has been a desire since my late teens, so you can imagine my excitement, then came the disappointment reading Otis' statement that people with 20/70 or more has slim chances of improving vision to 20/40 or better. Not exactly those words but something to that understanding. Naturally, I was very irritated of this "statement", where else I can find ppl with 20/200 or worse have improved to 20/20 vision. So I was thinking why Otis kept saying that & dampening people's spirit/motivation to improve their vision. So when I started, I was not so happy but persisted to use plus lens, thinking that I got nothing to lose.....and my vision started to improve
As time went by I understood, why Otis made such statement(after much reading). IMHO, it is not to dampen a person's spirit or motivation but NOT TO OVER CLAIM the "cure/prevention" and secondly, if you read at this place : www.google.com
then select Groups and type
sci.med.vision
You'll be astonished how a lot of people bash Otis. In my opinion Otis has nothing to gain out of this, he just want to spread the knowledge of the "second opinion" but unfortunately a lot people don't accept it.
So later I realized and began to have a different view why Otis keeps saying that. A better view of course.
IMHO, anybody who has no medical problem( eyes) has a very good chance to improve their vision. They can improve their vision with plus lens or with some exercises ( Brian is one of the best proof we have here ). You can do it with either one or with a combination of both. Which one works faster or better, I really don't know. To me it is purely an individual experience & effort. You have to do it yourself with persistence, testing & innovation.
I hope people will stop bashing Otis(at sci.med.vision) and I hope people will try which "system" works the best for them. I feel all methods has its pro & cons. Its a persons choice to pick plus lens or the exercises to clear their vision. If a person don't believe these choices we have, then they must just move on in life. Search for the ultimate natural "thing" to improve their vision.
Nobody can give guarantees & I'm sure there are disclaimers somewhere in the website.
Everything I said was based on my opinion, so don't use it against me. I sincerely hope that I didn't offend anyone in what I said above.
Oh yes, I also want to thank Robert & Patrick for their views, opinions & suggestions.
Just my 2 cents. Chill out everybody
Cheers,
Steve ___________________________________
Dear Steve,
Thanks for the write-up!
Most parents -- if offered the plus -- will recoil in horror, that their child must put on a plus for reading.
That is 99 percent of the population at this time. (I personally think they should go through an "educational" process before deciding to put their child in a minus -- with the either-or, now-or-never issue clearly explained to the parents and child.)
But AFTER a parent has cleared his vision from 20/200 to 20/30, he becomes sufficiently "expert" to understand the meaning and use of this "second opinion".
Now your children have a "fighting chance" to keep their distant vision clear through the school years.
That is what I "fight" for -- your right to an informed, competent second-opinion at the threshold when it can be truly effective.
Sincerely,
Otis

>Here is "Steve" a man who was "myopic", but decided >to make agressive use of the plus -- and clear >to PASS the DMV level test. Aw, DANGIT! You just slipped back into n=1, anecdotal crap that shoots apart any credibility as a "scientist" that you may claim.
Don't you understand the scientific method? Here. Read about it:

Trying to control the argument by controlling the terminology has never gained you credibility, nor proven your hypothesis (which--again, admirably--you seem to be changing EVER SO SLIGHTLY to discuss PSEUDOmyopia, not axial myopia. But these relapses ... sad ... so, so sad....).
In fact, somebody who pays attention to what it is you spout is *bound* to notice the contrived terminology you so favor and will readily disregard your ideas.
"proven dynamic quality of the natural primate eye??"
Who talks like that?

acemanvx@yahoo.com - 21 Dec 2005 19:13 GMT Nice read Otis. clearing 20/200 to 20/40 DMV is rare. You said most dont clear to DMV if they are worse than 20/70. Why arent optometrists giving everyone cycoplegic refractions so they can avoid pseudomyopia and stop their eyes from getting more axial myopia? Ive said several times already, I reeeeeeeally need a cycoplegic refraction and I am getting one asap! This will tell me how much myopia I can clear. True and full 20/10 vision is rare, many optometrists overstate your accuracy. I have already explained how. My sister's friend was declared 20/10 but she cant see any of the 20/10 and barely 8 out of 10 20/13. I have been declared 20/25 and sometimes even 20/20 but 20/30 is the smallest I can reliabily read. At least 25% cant be corrected to 20/20. 20/4 vision? Thats better than a hawk's 20/5! 20/4 would be able to see the 20/20 line from 100 feet! How good can human vision get Otis? One guy said it can get to 20/2 which is as good as an eagle but only like 1 in a billion have that. Its a freak of nature blessing type of ability! If it was hypothethical and I could choose to fly like superman or have eagle vision, it would be a hard choice! I get shivers just imagining what 20/2 looks like, or even 20/10! I seriously believe ill be seeing 20/10 oneday, probably not soon. They could have very advanced wavefront glasses or contacts some decades away that will give almost everyone 20/10 or better vision! In fact your retina will pretty much be the limiting factor and not high order aberrations which limit most people to 20/15 to 20/40 currently. I did read that theres special instruments that can simulate 20/10 vision for some people and an increase in your BCVA for almost all. It uses like 5000 tiny mirrors to correct your high order aberrations.
http://www.zinkle.com/p/articles/mi_m0BFU/is_12_89/ai_113644570
You can use a pinhole right now and at home for a little taste of slightly improved vision beyond your BCVA. Expect about half a line improvement but if you have alot of aberrations you can improve 2 or more lines! I improved my 20/30 BCVA left eye to 20/25 and my 20/40 BCVA(?!) right eye to 20/30 with half of 20/25 readable. I was amazed how rich the contrast was! Letters became noticabily blacker, the edges of the letters bolder and better defined, any doubling was greatly reduced!
http://www.aao.org/aao/news/eyenet/archive/01_00/cover.html
Machine with many tiny mirrors(100,000?!) that can simulate 20/10 vision for you. 99.9% of retinas are capable of 20/10 even if the corneal shape is only capable of 20/20, 20/30, even 20/40! The lucky few are 20/10 because they have very little aberrations while the unlucky can be 20/40 or worse!
http://www.llnl.gov/str/October04/Gilliom.html
Oneday glasses will correct high order aberrations and humans will see 20/10, 20/8 or even better! 20/10 will be the new standard of vision!
By one estimate, about half of the population has higher-order aberrations that produce a noticeable reduction in acuity and 15 percent would achieve a major benefit from having their aberrations corrected.
Unfortunately, it is more difficult to conceive of how spectacles with wavefront-corrected lenses would work because the lenses would either have to move as the eye moved to keep the optical axes of the lenses aligned with the eyes, or the shapes of the lenses would have to be constantly changed to maintain the proper alignment with the eyes. Neither alternative seems feasible at the present time.
My comment: todays wavefront glasses technology does exist but youd have to perfectly align your eyes to the wavefront impression in the glasses to see perfect. Your eyes are always moving so this isnt possible till they make glasses with many tiny lenses that constantly move with your eyes. Big technology hurdle!

good article that explains why some people have better BCVA than others.

1. Your a great optometrist! 2. No but they detect it(ditto to latent hyperopia) and the approperate action can be taken. Any pseudomyopia I have I can work to clear this. Its good to know my cycoplegic. 3. How long does pseudomyopia last anyhow? I want to get it out and be seeing the best I can. pseudomyopia is impairing my vision for nothing!
"Oh! So you think acuity measurements are based on what you can "reliably read?" That could be part of the problem."
Well let me explain it in a way everyone can understand. Theres different levels of vision even if both read the same line. I can read 18/25 while dad can read 22/25. The optometrists consider both of us 20/25 but my dads reading the 20/25 line easily and without missing a beat. No problem for him. He cant quite make out 20/20 still. I on the other hand cant quite make out 20/25 but for some reason the optometrist insists on me trying anyway. I strain and guess my best on shape reconization and if im lucky I get some right then the optometrist smiles and looks satisfied and proclaims me 20/25. Some people say the snellen chart should have more lines like 20/18, 20/22, 20/28, 20/35, etc. Right now it goes in 5s like 15, 20, 25, 30 and in 10s like 40, 50, 60, 70, 80. After that theres a few lines and it stops at 400.
I guess you could consider me between 20/25 and 20/30 but since theres no line between that, 20/30 is the next line I can read. Many people between lines can guess a few on the lower line
"You're off by a factor of 10. Among healthy people your age, it's more like 2%. If accuracy matters."
Were talking full 20/20 here, no getting lucky with guesses, no half way counting. Age doesnt have much to do with it, high order aberrations do. Hey ive seen "old" people see better than 20/20 as well! Its true many old people lose eyesight due to cateracts, refractive errors(commonly hyperopia) and other diseases but a healthy "old" eye is the same as any healthy eye.
"Where did you get this from? You may get improvement from Wavefront specs, but not perfect vision, especially if you have crap optics already."
well the first generation wavefront glasses dont work for 9 out of 10 people. Crap optics doesnt matter as long as my eye and retina are healthy. high order aberrations is like complex astigmastim that can be corrected but we dont yet have the technology to fully correct for this, but once we do, most people will be 20/10 or better. 20/10 may become the new standard like 20/20 is now.
"Who cares, noone wears retainers through the day."
They have to be worn a number of hours and I can choose to wear them when I get out of the house for the sharpest distance vision. Around the house it doesnt matter. I dont know how much better vision is with retainer lenses than without but if I was really concerned about it, I may be better off with RGP lenses then. I am just concerned about reducing my glasses dependancy and of course I can enjoy much sharper vision anyway.
"What planet are you from? OK isn't for people who are unconcerned about their vision. It is for people who want good vision."
OK means as in okay. Lasik gives improved uncorrected vision, that much is pretty certain unless your a very low myope.
"It is not the alternative to Lasik, as Lasik is not the alternative to glasses. It is simply another means of correction, admittedly a brilliant one. As with Lasik, all appropriate measures need to be taken to ensure that the right candidates are selected."
You are right, lasik, glasses, contacts, orthoK are all ways to improve uncorrected vision. Lasik is the most convinent of the following vision corrections but its also the least effective with many people regressing, still needing glasses, developing complications, etc. Contacts, especially RGP is the opposite of lasik. Its the least convinent not to mention its also not always comfortable but the most effective. Glasses are like a middle road. I consider glasses more convinent than contacts. Ive worn soft contacts and was aware of their presence and my eyes felt dry and achy much of the time. If lasik goes well you wont feel it and youll have natural uncorrected vision, albet at reduced quality and often accuracy as well.
"I ain't doing Lasik. Even if I needed it. Even if I was a candidate.
Not my choice."
Well your probably happy with glasses and/or contacts and you expect more than what lasik can deliver, ie perfect vision.

Or how about I work hard to clear my pseudomyopia now so I enjoy good vision a year from now and not when I get old?
"Before you "explain" it, you might read a little about accepted psychophysical measurement techniques and how they are derived statistically."
I will search this on google, but like I said, two people can be both "20/20" or both be "20/25" whatever and yet they can compare visions and one "clearly" comming ahead of others like reading street signs first, being able to see the prices at a greater distacee and then theres also quality of vision. Me and my dad both got labled 20/25 yet my dad can constantly see better than me. I have friends who claimed they were 20/20 and some couldnt even read signs and bullots, such as in a store from as far as I could. I told them no way your 20/20, im 20/30 and you cant even read as far as I can!
"Then you don't understand how acuity is measured."
Then different optometrists have their own ways of measuring accuracies. Some optometrists "get" lots of 20/15 results while others get less than 50% who measure 20/20. The eyecharts they use, how their eyecharts are calibrated, how far subject stands from eyechart, the quality of the eyechart, the illumination of the eyechart and room, the policy the optometrist employs all factor in how youll get. Over the years I can tell you most optometrists have considered me a 20/25 but a few have considered me 20/20 and some consider me 20/30. I do not see as well as a "real" 20/25 person. Again, ive challenged my friends who were told they were 20/20 and they all scored differently, most of them scoring between 20/20 and 20/25 in reality with some barely even scoring 20/25!
"So what are "cortical haze" and "diminished contrast sensitivity?" Like most doctors, I consider 20/15 to be normal acuity for healthy young adults."
Even if so, this doesnt make 20/20 abnormal in the least and its still a VERY good accuracy, period. Normal accuracy in younger people is 20/20. 20/15 is above average, better than normal. Just google it and youll see. Average drops in older people only because many develop diseases. If your eye is healthy you can keep your good vision.
20/20 vision Many eyecare practitioners consider this the average visual acuity for human beings, but some humans can see as well as 20/15 or rarely, even 20/10. People with 20/40 vision can see clearly at 20 feet what people with 20/20 vision can see clearly at 40 feet. In most of the United States, 20/40 is the lowest uncorrected acuity required for a driver's license.
acemanvx@yahoo.com - 22 Dec 2005 07:58 GMT "Few people can read 20-15 or better. The average good vision is 20-20."
http://wb11.empowereddoctor.com/story.php?id=87
"People with unusually good eyesight, usually kids, may have 20/15 or 20/10 vision)"
Well im not a kid anymore but an adult. Yes its more among your very young fellows but notice that 20/15 or better is *unusually good* as they say!
I just dont think such super vision as nearly as common as you say *unless* maybe all the sharp eyed guys drop by you for a visit ;)

Acuity is acuity. If you don't standardize the test instructions and test conditions, you get variable results.
