I have severe astigmatism and have been told that I have a good chance of losing my eyesight in one or both eyes due to the stress.
If that happens, yes, I hope to be able to be able to do at least some of what I do. I'll have to do less, and it will be harder, but I will deal with what I have to deal with as best I can.
Believe me, I think about this often. It's a bit more than theoretical for me.
