Thanks so much for recounting your experience.
When you wrote, he was “blind as a bat”, I hope that was a figure of speech to mean he had poor eyesight.
That was a problem that ran in his family.
However, he was not blind.
He certainly did need strongly corrective lenses.
The problem is there is so much misinformation about the man, and on the net you find people who assure everyone that he was totally blind.
Untrue.
I still have a couple photos on my phone that I took of Roy's High School Year book photos... lemme go hunt them down.
