A few points I would like to mention, I have similar issues so I think I know where he is coming from.
1)"I keep thinking I'd like to get some safety glasses mad that will be a reading glass lens on the right but plain on the left (I haven't seen custom glasses like this for a reasonable price, though)."
Not sure what you mean be reasonable (varies widely among people) but check out your local WalMart. Many have an optical center and do good work at a reasonable price. I forget how much I paid but it was basically the same as regular glasses.
My glasses are safety glasses with side shields with the left eye focused at far distance (Infinity in photographer terms) and the Right eye focused at 39 inches (distance to the front sight on my primary firearm) no extra charge for the disparity. I was told that this distance is sometimes called " computer distance " and it may be easier for you to explain it that way. I just told them that I am a target shooter, true statments BTW
, and had measured the distance ahead of time with a friend.
You WILL have to explain exactly what you want and express frequently that you want the lenses set at two different distances. Tell them you want "monovision".
For some reason I cannot explain most optical workers cannot believe that someone wants the lenses in their glasses set for two different distances even though they do it routinely with contact lenses. My glasses have been ordered correctly but made incorrectly i.e. they did not follow the order that was placed. This has occurred on several occasions even with the manager involve.
2) Try everything for yourself using the metric of accuracy/speed for your area of shooting. Rent a Eotech, try an Aimpoint or mini-red dot, or a laser either green or red. Or you can celebrate the season by getting both!
Does not matter what the experts say what matters is what lets you use a gun the way you want. What is good for a IPSC person may not work for a Benchrester.
When my moms eyesight went bad she request ( and received ) a Glock with a LASER back in the 90's. Many tried to talk me out of it. 5 out of her first 6 shots were int the cardiac silhouette! (Mom was a retired ICU nurse
)
Good luck, YMMV and all of the above is just my opinion.
