Sorry about a bit off-topic and not directly answering your questions but your story resonated with my experience. Maybe it might help you or not :)

I've had surgeries on both my eyes for retinal detachment before I was 22 years old (30ish now). I am now handling myopia of -16 due to bad eyes and post-surgery effects. I don't want to insinuate that you have the same conditions but I dealt with similar symptoms. Sudden loss of vision, dark circles and dark drops passing in the vision is a scary and distraught feeling.

The thought process you describe happened to me as well and is still in-progress. Dealing with the fact that having such issues "early" in life poses questions and anxiety for what might happen later. I kind of navigated over the years with two ways of dealing with this. First as you today with the ideas of pro-active actions to prepare for the day I might go blind: learning braille, using a computer without or very poor sight and thinking about possible career transitions.

I was lucky enough that the surgeries went well and my sight "kind of" stabilized. Over the years I adopted a more "optimistic" approach. Even with a bad start, it is still only a possibility and not a certainty to become blind. I decided to live my life as fully as possible with my current sight and avoid to end-up in a anxiety circle about it. Who knows I might still have my sight for life. And by the time it might deteriorate, technology and medical science will have improve, thus hopefully increasing the chances in treatment, tools and possibilities.

Good luck for everything.
