Vision problems - open topic for experience, treatment outcomes, etc.

So after yet another round at the eye doctor yesterday, it seems my glasses prescription has been all wrong for some time (!?). I've been told I am/am not a candidate for LASIK. I've had whole diopters of change in prescription over six-month periods, An ""uncorrectable" astigmatism in one eye from an old orbital bone fracture has corrected itself suddenly (yay?).

What reading I've done suggests that the research basis for understanding the biological mechanisms of optics in the human eye and visual information processing in the brain, versus various styles of correction, is bogus (to put it mildly).

The incidence of severe myopia/astigmatism is rising dramatically around the world, not coincidentally with screen time, and it's getting more difficult to treat adequately. Anyone else feel like they're going blind slowly, and are there any evidence- or experience-based, reliable solutions you've found?
