Dear Second-opinion friends,
Some more commentary on using Ortho-K to clear to 20/20, followed by strong use of a +3 diopter to retain distant vision.

Dear Yves,
The reason I make my "pitch" to would-be pilots is because I know how difficult plus-prevention is.
To a certain extent you must believe it is possible to do it -- before you do it successfully -- if that makes sense.
That is why my site has the "Eskimo" data on it, as well as the "primate" data. By itself "facts" are not convincing, but they do "point the way".
We both know that plus-prevention is an INTRUSION in your life -- intended exclusively for your own personal benefit.
By that I mean that "I" do not tell you what to do, but rather you explore the concept and then YOU determine what YOU wish to do for your visual future.
I am VERY interested in your progress by working interactively with Ortho-K and the plus, since I am not aware of anyone who has done it they way you plan to do it.
You got it right! Use Ortho-K for a week or so, and then stop and rely on the +3 diopter for all close work that is convenient.
I expect that your corneas will spring back, and your Snellen will start down towards 20/50. When that happens, just re-start the Ortho-K again.
I think that at each iteration the amount that your Snellen "comes down" will be less and less, until you will retain 20/40 or better as required.
As Stirling Colgate said, with periods of LONG close work, his Snellen would come "down" so he just re-started with the plus and cleared it when necessary.

Otis> I started the myth ... sorry! Most people will not "do Ortho-K" unless they have pilot-motivation.
Yves> But i do finally believe now that Plus prevention works.
Otis> Good, but only you will know this when you can retain 20/20 with no further use of Orth-K. I would suspect it will take from 3 to 5 months. But I can not predict it.
Yves> I'm starting to notice that by the end of the day after I use the +3 for 8 hours at work, my vision actually improves since I was just able to see half of the 20/10 line at night more than 12 hours after taking the ortho-k off.
Otis> That is INCREDIBLE. The goal is official 20/20, and most of the DMVs only require 20/50 to 20/40.
Yves> I think i'm starting to realize why plus prevention takes much longer for people with higher Diopter, the main reason is the dependence on minus at some point during the day, which probably kills the whole plus prevention effort.
Otis> That is correct. A strong minus is impressive, and often over-prescribed (i.e., strong enough to create 20/15 vision). That is impressive and "sells". Tragically the majority-opinion ODs refuse to believe that their is a "secondary" effect, in that:
1. The original issue (eye adapts to near) is NEVER addressed, and,
2. The total belief that a minus has no effect on the natural eye's refractive state.
Otis> They believe this AGAINST a massive body of scientific evidence that says the exact opposite. Oh, well...
Yves> With ortho-k however there is no minus grudge to mess up your vision, so you can understand and see the results much clearer.
Otis> I am pleased you took that step with Ortho-K. That could be a "selling point" for Ortho-K, and I would support it. Getting to 20/20 very quickly is impressive to BOTH of us. The only issue is to retain it, and slowly reduce and end the use of Ortho-K. Or at least that is the "hope" for now.
Yves> That's my opinion... This weekend i'll try to skip a day and see what happens. Will keep you posted.
Otis> All posting here are VERY INTERSTED. Keep up the good work and commentary -- about any subject you wish.
Yves> Thanks Otis for everything you are trying to do to let the people understand the second opinion.
Otis> Excellent! There is many a pilot who could learn from you!
Otis> Life is a journey. So let us travel this road together.
