I've been doing the method in your second link (tl;dr: buy every pair of glasses between your prescription and 0 in 0.25 diopter increments, and slowly work your way down to 0).
I started at the beginning of quarantine, and it's actually been a wonderful time to try this since I rarely /need/ to look at anything farther away than my laptop screen. I started at a -2.25 diopter prescription in each eye. So for about $120 I got every pair of glasses down to 0.25 diopters, and a Snellen chart to track progress. Today, I'm down to a -1.25 prescription, although I plan on seeing an optometrist to confirm this once it's safe in the world to do so again.
The things I noticed during this experiment:
> It takes about a month minimum to drop down a prescription (I measure it as once I can reliably read to the 20/30 line on the Snellen chart).
> Given the above, I wear `current prescription + 0.5 diopters` whenever driving to make sure I'm well above the legal limits for driving (which is 20/40 vision)
> Going outside and just looking at stuff that's far away has the biggest positive effect on improving vision.
> Given 30 seconds of actively focusing, I can see temporary gains to my vision for the next 30 minutes or so
> My vision is waaay better in the morning
> I can now work on my laptop without needing glasses (still difficult to watch tv, though)
> Given the focus on what is and isn't blurry, I've started noticing the insane effect the brightness of a room has on how blurry things are
> I'm terrible at tracking data, given that I only have about 10 entries in my very basic excel sheet
> This has made me go on walks more often, which is just a net good all around. It feels "productive" to go for a walk rather than boring.
> It's very possible that this has only a limited return it can provide, since I've been plateaued at -1.25 for the last 3 months.
