Thank you very much! Now I remember the term "Yag." :)
And thank you for your honest opinion. I think wearing a light prescription is a good compromise, and I agree that it's not worth risking messing with my eyes again since I've been happy with the results I've had so far.
Do you remember the episode of I think "The Twilight Zone" where the man who loved to read was locked in a bank vault during his lunch hour when a nuclear disaster wiped everyone out? He was so happy because he could just read for the rest of his life---until his glasses broke! I think about that sometimes. Not that I expect that to happen, but I've been without my glasses sometimes and it's been a hassle.
However I think the solution to that is to have lots of spares!
Anyway, thank you again for your excellent help, and good night!
