Hi Harry:
My 35th anniversary was a few days ago. I have always admired how you support your wife.
Currently I am in limboland with negative VEP's. However, I had give up reading about four years ago and when I am tired or having a setback I get double or blurred vision.
MS does damage the optic nerve unfortunately. I can still knit, but patterns confuse me. It's extremely frustrating, a daily problem. I'm sorry your wife is not able to read.
