Blindness opinion

Wow just imagine that your just living your daily life on just a regular day,and all of a sudden for some weird and unexpectedly you go completely blind. I would imagine that if this happen in real life I would think the doctors and nurses would go blind too. Unless they would have a protected power that keeps them safe from getting blind too. But realistically your not going to get blind from catching it from someone. Its not a contagious disease but other wise I like the creativity in this book. Its different from anything I read. I'm not really into syfy type stuff but this book is interesting.
