Can you please share that routine with me? I'd love to chuck the glasses altogether.
If you do it right, you won't chuck the glasses, just end up with glasses for near work to prevent sliding back into Myopia again.
Basically, in a nutshell, the eye is both a self-calibrating device, and capable of accommodation both towards you and away from you.
Most of us are familiar with the accommodation that allows seeing closer. Most people are unaware that you can actually push your vision a little bit further than the "relaxed" state of the eye.
The eye is most relaxed at a certain focus distance. "Normal" vision people have that focus distance far away or infinite. People like me have their focus distance closer, mine is about 33cm (it used to be 20cm). I can focus closer than that, and I can focus a bit further than that.
The other part is that the human eye is self-calibrating. There is simply no way one can encode into a few genes the recipe for accurately calibrated eyes, that stay calibrated as the eyes grow through childhood, and stay calibrated over potentially a century.. Eyes grow, every pair is different, etc, etc etc. So the eyes "calibrate" over time. If you spend a ton of time looking close, they will recalibrate so that you naturally see close without trying. We call that "myopia", or nearsightedness. If you spend a ton of time looking far away, the eye will recalibrate to see farther. We call that "hyperopia" or farsightedness.
The two ways that the eye calibrates are based on where you spend your time looking. I spent a ton of time as a kid looking at computer screens and books. Thus my eyes calibrated for that distance. I then went to an Optometrist, since far stuff was blurry, they gave me glasses to look at far away things. I stupidly wore those glasses for close up stuff, leading to repeating that calibration cycle over and over again until I couldn't see naturally more than 20cm, or 8".
That process works in the other direction. By pushing your eye's focus further than that the "relaxed" position, the opposite occurs, the eyes recalibrate towards distance vision.
Both processes are very slow, typically 0.75 to 1.25 diopters a year when done to an extreme.
So far, after a year of this, I can now drive at dusk with -3.0 diopter glasses and see as well as I did a year ago with my last "prescription" of -5.0 diopters. It does work. I estimate that I will no longer need glasses for distance vision in about 2.5 years, at the current rate of improvement.
But it takes discipline. I was disciplined (inadvertently) to get myopic, by constantly looking at stuff up close with my distance glasses for hours each day. To go the other direction, I spend most of the day at "the edge of blur", or with a prescription that's too weak to let me see clearly without pushing focus. I also avoid looking closer than my current prescription as much as possible (e.g. I take off my glasses to look at my phone). But accommodation in the push-out direction maxes out at 0.5D, while near accommodation is 3 to 5D. Thus I have several sets of glasses that I'll switch between during the day, and have to step them down every 10 weeks or so. Much more of a hassle than when I was making myself nearsighted! And certainly more work than getting my eyes zapped by a laser!
And the kicker is, once there, the glasses don't go away. If I don't wear glasses while on a computer or phone when back at 20/20, that makes me pull focus in, which starts the recalibration over again to make me nearsighted. That's like going on a diet, losing 50lbs, then going back to my old eating habits. Baically a recipe for undoing all that hard work. The remedy? Plus glasses for close up work. Thus the glasses don't go away.
So if I'm not going to ditch the glasses, and it takes years, and dozens of pairs of glasses, why bother? I want to see if it can be done! Everyone says myopia is a one-way street. I have experienced the fact that that isn't true. So I want to be there. And I'd like to try using glasses only for near stuff for a while! =)
Check in with me in a few years, I'll let you know if I'm successful in getting all the way back!
I've already seen another payoff. My 7 year old started getting a little near-sighted (about 0.25-0.5 diopters). I got her glasses. But not regular near-sighted glasses, I got her reading glasses! She wears them for all her close-up work (never for far viewing). Within a few months, she now she sees like an eagle, and will likely never develop myopia in her life. Knowing how the eye calibrates and how to manage that has made it so my kids will never have to live near-sighted like I do. And that is even better than me seeing 20/20 again.
