Cause of blindness question: The character in question is losing his sight completely in an accident of some kind. The scenarios I have are all explosions, but other accidents are okay as long as they could destroy his sight in both eyes suddenly and permanently. Other damage/scars/etc. is okay, but for every scenario I've come up with, it feels contrived for him to lose both eyes at once. I looked into retinal detachment, but I don't want it to be treatable (part of the point is that he has to adjust to doing his job, which relies heavily on sight, without sight/while asking others to be his eyes). How could he lose both eyes, at once, probably in an accident without it being overly contrived? (I don't know how much it matters, but he has a brother who could and would pay the cost of just about anything even remotely treatable.)
Transition question: I've been able to find resources detailing how he'll have to change his practical life, but for some reason the emotional impact is harder to find. I found a couple articles, but they require subscriptions and deal with older individuals and probably more gradual change. The character considers himself a sociopath, but he would have a reaction and I want to respect the reality of his situation. I can guess, but I don't want to just guess about something I have no experience with.
Thanks in advance!
