It’s time to put this question in the FAQ.  Diopter reductions, where to start.

First, obvious disclaimers.  Don’t monkey with lenses if you don’t know what you’re doing.  Don’t go dig up some “old prescription” and start wearing it.  Learn about the biology first, learn centimeter measurements, do a ton of reading, before messing with focal plane changes.  That stuff is no joke and you’ll do way more harm than good by going into this experiment without a clear background of why and how and what.

So let’s assume you looked through the FAQ and you learned how the eye works, and you looked at some proper clinical science and you read my 7-day free guide, and you did a whole lot of centimeter measurements

Now you joined our FB group and have been reading (while not asking questions without searching the site first).  You feel ready.

So where do you start?

First, you face north and in your most serious voice proclaim to all of your gods that you will not consider anything we say to be medical advice or prescription advice, and that you, and only you, are responsible for your own fate. 

You could face east too, and just mumble, or face the screen and nod your head.  Either way.

Now this is where you start.

Close-Up First.  Always.

You don’t mess with your regular glasses till you have close-up sorted, well and proper.

That’s where your myopia started, and that’s where reversing it has to set out from.  You need to get ciliary strain awareness (Google the keyword endmyopia and close-up strain as a start, for example).  You need to look at your centimeter measurements and understand the diopter bubble (a quick search) and figure out how much correction you need for close-up.

We call those the ‘differential’ glasses. 

This process will do a whole lot of your in terms of learning and understanding your eyes, all while not messing with your normal distance vision needs.  Handy. 

Also for illustration purposes, look at this post in our FB group:


Less efficient than Jake’s way.

See what I’m going on about?

If you start out with your distance glasses, you end up messing with your distance vision needs, possibly spending a bunch of money, and keep doing so till you find the floor in that correction – and what you actually need for distance vision.

On the other hand if you follow my advice above, start with close-up (differential), you skip a lot of doing things the hard way.

Here are some of my comments in the FB thread:


Easy when you know how.

There’s a lot to go on here when you’re getting started with better corrective choices.

And if you do want a structured approach and my personal guidance, you can always try to get a hold of a BackTo20/20 invite, and skip a lot of the effort of piecing things together.  Of course my personal time isn’t quite free, so there’s the trade-off between convenience and cost.

Either way, go make some 20/20 gains!
