Definitely check out endmyopia.org. It's a great site, he's got a facebook group, you can follow along with real people who have real results.
From what I've learned from endmyopia in the last day:
Regarding eye length, when you do a lot of close up work, the ciliary muscle has trouble relaxing again for distance, and therefore focuses in front of your retina. So you get glasses to push that focus point back until it's projecting on your retina.
Problem is that we tend to keep those glasses on for close-up work, so your eye gets longer to compensate. Which means once again you're projecting in front of the retina for distance vision. So now you need a stronger prescription.
So he recommends two things:
1. Stop using your glasses for close-up work. Read at the point where it's just blurry, but you can read and let your eyes slowly adapt (called "active focusing"). If you can't read from 12 inches away without glasses, then you need to get what he calls "differential glasses". These will be less than your current prescription, used only for close-up work. Alternatively, you could wear plus lenses (reading glasses) over your contacts or over your regular glasses.
2. Step down your current prescription by about .25 diopters (except for driving, of course). Use these glasses for all distance time. Look for the blur, and practice active focusing, which is where you basically will your eyes to focus. Kind of like weight-lifting, where you will yourself to lift a heavy object.
So far, I've been doing step 1 for the last day, and I'm amazed by how far away I can read, and I'm noticing the bad habit I've had of reading really up close with my glasses on. Supposedly, this is what caused the damage in the first place.
Already, I've noticed that when I put my glasses back on for not-close-up time, it is literally clearer than it was before when I was reading up.
I'm going to do a bit more reading before I figure out exactly what prescription to order for distance work. Basically a bit less than what I currently have. According to the site, on average, you'll go down .25 diopters every 3 months. Which means I"ll be glasses-free in 3 years!
