Welcome to the threshold of seniority, Gunner!
If the tops really work well at infinity and the bottoms work really well at whatever distances you read and do close work, then the glasses are right.
One solution is trifocals for midrange. I've never tried those, but I'm quite sure I wouldn't like 'em.
Another solution is variable gradient -- no line. I have tried those and hated 'em. The region where anything is in focus (other than infinity) is small, so reading is like watching a tennis match and working under a car where mobility is misery.
You can ask your optometrist for a mid-range Rx, and have some cheap readers made to that Rx to use when working at a 'puter. I did that and I like those a lot.
I had my current bifocals made so the comfortable close range starts at about 12". That's not usual, but it's what works fer me. A good optetrist can make the Rx match whatever ranges you want (within limits of your vision capabilities) if you tell her what you want. They're then good for both reading and for use at a 'puter monitor, so I don't need the 'puter specs anymore. I use flip-up Optivisor, 3 diopter, for close work. They're on my head almost all the time in the shop.
I have 2 diopter flat plastic fresnel lenses in my welding helmet. They're cheap, less than 5 bux at a welding store. Huge help with TIG and MIG.
There's a little pinhole aperture gizmo with a suction cup that sticks on to my glasses. That helps a LOT with handgun and targets. I haven't tried it with rifle because I have scopes on my rifles but I think if anything it'd work even better with the more distant front sight. The commercial version with a little iris is pricey, but a dot of foil with a pinhole in it would work just as well if you could get it to stay put.
I plan to take a "point 'n shoot" handgun course this winter that doesn't rely on use of sights at all. I know that's been found wanting by L.E., but I think it's a matter of practice and I am more than willing to practice. Hell, I look forward to it.
Write back when you're ready for hearing aids -- and I'd bet large that you will be eventually. Just about every vet over 60 I know has some hearing impairment. Mine started being noticable about age 57 and got to be a nuisance at about age 60. Getting older is not for wimps!
