I know it's nothing in itself, but the progress in a few year was significant, and my doctors told it to me. It was a huge dégradation in a matter of 5 years, while I was already old. I wondered what was the thing that started the bad progress. Maybe because I got a phone with unlimited internet and kept using it, maybe because of poor light in the offices (during my first job, despite being on the computer all the time, I had no sight loss, because the light was actually pretty good). I think no matter what your correction is, you should take the steps to not make it worse, and I find that there's very little information about that. Even doctors just say "look far once in a while" which doesn't see so efficient.
