Ben Stoeger recently did a podcast on this:
https://www.benstoeger.com/practical...ter-dark-ep-16
6:45 starts talking about lenses
9:30 starts talking about shooting target focus all of the time
I'll be spending a LOT of time with Ben from perhaps today through Tuesday, so if you have any specific questions you would like me to ask, now is the time.
FYI, I'm testing a new change. I am normally near-sighted and can see my front sight well, but the target and rear sights are fuzzy (even if I use target focus),
The change is to use a single contact lens to correct my non-dominant eye for distance, leaving my dominant eye uncorrected with a front sight focus. When looking at a target I see the front sight clearly with my dominant eye, and the target (more) clearly with my non-dominant eye, oddly without changing focal depth.
I hope to try this out for real Sat-Tues, we will see if my brain can adapt and I can stick with it.
