My eyes are old and decrepid but with mild astigmatism and lots of presbyopia. My wife, for my birthday, made me get a pair of trifocals. Yes, trifocals (goans of consternation).
So, I decided if I was going to get a set of trifocals made, I would have the center lens set so I could focus on the sights of my handguns (at natural shooting positions).....
It ends up the glasses are not very good at shooting guns--which I won't discus further. But they are just perfect for shooting pool! The reading prescription at the bottom allows me to see the cue stick, the shooting prescription in the middle allows me to see the cue tip and CB, and the distance prescription allows me to see the rest of the table--all in pretty good focus.
