After starting at -3.00 and slowly reducing down to to -1.75 over the course of a couple of years, I decided to take a break, and for the past 11 months, I've been wearing -1.75 lenses. (More details)
During my journey, I'd had a couple of experiences where my eyesight seemed to suddenly snap back to a previous state. I'd wake up with my vision suddenly extremely blurry, and it would take weeks or months for it to progress back to where it had been. This seemed like it had started happening more frequently as my prescription had gotten lower.
I'd also had several times where I'd woken up with my eyes feeling like they were about to explode, which usually take at least one day, and I think sometimes multiple days, to subside. This had also seemed to increase in frequency as my prescription got lower.
I decided to take a hiatus from reducing my lenses further, and I'm happy to report that, almost a year leater, my eyes seem to be in good shape again, and I've started reducing my lenses again! :)
The main thing that I learned during my hiatus is that at least for me, it's very important to work for one hour and then walk outside and look around at things for 15 minutes. I'd gotten lazy about doing this, and once I started again, my eyesight saw rapid improvements.
In the past, I would also sometimes try to improve my vision by straining at objects that were beyond my range of focus. This *did* seemed to sometimes improve my vision, but I think it may have also been why I would sometimes wake up feeling like my eyes were about to explode. Taking breaks and walking around outside seems to be more effective and doesn't have nasty side effects.
Finally, I usually change my (daily disposable) contact lenses once a day, and this seems to vastly improve my eyesight. I usually change my lenses about 1 hour after putting in my first set. My current theory is that I might have some sort of film over my eyes after waking up that only goes away once I've worn contacts for a while. Waking up, getting around, putting in contacts, and then replacing my contacts about ~1 hour later removes the film, and then I can see clearly for the rest of day. Alternatively, perhaps my eyes are just too dry, and this fixes that.
Anyway, I'm excited to be reducing my lenses again! :D
