There's nothing wrong with your eyes, you just need stronger glasses...
I had an elderly ophthalmologist tell me with a perfectly straight face "there's nothing wrong with your eyes, you just need stronger glasses". This, as an answer to my grave concern over suddenly started, fast eyesight deterioration. At which point I decided they just haven't got a clue (but don't have the guts to admit it, the cowards!) and started my own research. By the time I found endmyopia.org, I had figured the connection between starting to wear glasses for close-up due and on-going deterioration, only didn't really know what to do about it other than stop making things much worse. Finding endmyopia.org in this situation was like finding the veritable pot of gold at the rainbow's end. The truth about myopia is kinda shocking but also blindingly (pun intended) obvious when you finally come across it. Since then, slowly closing in on being able to use the computer without glasses again. It's huge. Just don't expect any miracle cures overnight, it's a long road ahead. Endmyopia has a paid programme for a guided tour to getting your eyesight back, but the fundamental information - a wealth of it - is freely available. Which is just the way it should be: some like to DIY while others prefer paying others to help with the heavier lifting, you get to choose whatever works for you after assessing the situation based on the free information. It's actually not entirely unlike how the open-source software ecosystem works.
