Thanks for the clarification. I had sepsis and the outcome was my vision was affected, I still see double. sometimes. Upon an eye examination shortly after the incident I lost 30% of distance vision. The first year the words would melt down the page, or lines would disappear, that part of my vision is better now. In April of this year my vision was considered legally blind. After cataract surgery, my vision now only requires drug store readers and most times not even then. Sorry about your dad, it is very annoying when your field of vision is obstructed. I wish him well.
