I have some eye problems also, legally blind, but corrected by glasses. But my eyes are still bad, even with the glasses, I have to take off my glasses and get my eyes within an inch or so for detail work. The bifocals are supposed to deal with that but they just dont. I was really scared when my eyes first started going bad, but they leveled out on their downward slope of ability. I also was afraid of going blind. Plus I have really bad foot problems, and dont hear well. All together, I am thankful I am not fired from my work. But at least I am 60, and I can take early retirement at 62, and hopefully work part time to make up for the income loss.
I understand the fear, and I am glad to pray for you!
