As you probably already know, the single prescription paradigm of mainstream optometry is the #1 contributing cause of progressive myopia. Glasses intended to correct the focal plane for distance, cause all sorts of problems when used for close-up (not the least of which being hyperopic defocus, stimulating unwanted axial elongation).
But that’s not news to you, if you visit here regularly. You know that you need to account for close-up, with the correct focal plane change for the distance.
There are multiple ways to manage your close-up focal plane, depending on your degree of myopia, close-up needs, and personal preference. I recommend glasses for many cases, though some might want use contact lenses instead.
Eli is one of these cases. He wears distance contact lenses and compensates the focal plane for close-up, with plus glasses. That’s worked well for him, though now it seems it’s time for a change.
Here’s what Eli just posted in the forum:
Two diopters improvement to date. Nice!
So this is obviously a pro topic. Don’t monkey around with lenses and prescriptions if you don’t know what you’re doing! Consult a friendly optometrist, know the local laws, etc etc disclaimer-town.
Here’s what I suggest to Eli, in the forum:
First of all, congrats on the two diopter drop. Nicely done.
To replace the current solution with differential in glasses, just subtract the plus prescription number from your normalized contact lenses (extra step, convert the contact lens values to glasses equivalent: https://endmyopia.org/convert-contact-lens-prescription-glasses-prescription/
Do that rather than by the generic -1.5 recommendation for best results.
Carrying around two pairs of glasses isn’t super fun but you end up working out a system for it. Back in the day I’d have a pair in my laptop bag (very mobile office lifestyle). Others may keep them at the work desk. I’ve had students who bought all sorts of interesting folding contraptions for pocketability (usually available as reading glasses, people will buy them for the folding frame and then get their friendly optometrist to cut them lenses for it).
I actually *like* the inconvenience factor. Ongoing reminder that these things are crutches that we want to get rid of. Contact lenses have that “set it and forget it” aspect that doesn’t really do much for ongoing motivation.
I reversed a whole entire five diopters of myopia, for myself.
It was a relatively gigantic pain in the ###. There are so many little tricks, so many variables, so many things that are no fun at all to figure out by trial and error. I wasted years, not knowing the things I know today. These blog post highlights of my forum support, hopefully help those of you who want to improve your eyesight without spending money on the fancy business of BackTo20/20. I don’t want you to have to figure out all these things by yourself, either way.
And of course if you do want my personal support, access to thousands of forum threads like the one above, and a structured approach, then do get BackTo20/20 (e-mail me for an invite if the automated system won’t let you have one – it’s still stingy). I’m feeling all newly motivated to promote things just a bit, with the new logging tool busily collecting participant improvement data. Food for a future possible published study on natural myopia control!
Cheers,
