What are you doing to work yourself back from nearsightedness? Just curious!
Well it's a long story, but in essence, I'm nearsighted because of tons of time looking closer than the neutral focus distance for my eyes. Then I got glasses to "correct" that and the cycle continued again, over and over again until I peaked at about 5.5 diopters in 2001.
Well, it turns out you can push focus about 0.5 diopters further than the neutral point and that drives eyes in the opposite direction. It's why far sighted people also get worse with time.
I use a bazillion glasses of various powers to keep my eyes having to push focus at different subject distances. It's much harder than inducing myopia because the far sighted accommodation range is so much more limited than the eye's ability to focus close.
My current attempt started at 4.75 diopters of myopia (neutral focus) last Jume, and is now at about 3.6 diopters that I can actively push down to about 3.2.
My back of the napkin calculations is about 1000 hours of pushing focus like this (with minimal close focusing) per diopter. So it takes years But it took that long per dioper to get myopic, it just was so easy I didn't notice it. I'm hoping to be able to see stars as points naked eye again sometime in 2023/2024.
So it can be done. There is a small community that does this, PM me if you want the link.
