I've progressively been dealing with the issue in reverse. I'm far sighted but for most of my life I could still focus on things up close. First I started needing a magnifying glass for reading fine details like small decals, then a couple of years ago I finally had to start using reading glasses. So far just the cheap drugstore ones. Technically I just need the +1s, but I've started using +1.25 and +1.5 for doing really fine work.
Being far sighted, I don't have the adjustment to distance you are dealing with as arms length or further I can just remove the glasses.
My Dad is also a modeler and has the same issue only being older, he needs more glasses. It is almost comical, but he just hooked a coat hanger over his work bench and has probably a half dozen pairs of reading glasses in various powers hanging from it, plus a few spares.
Also agree with the work with good light comments. Initially I was able to avoid reading glasses with good light and it still helps. I ran track lighting over my work bench a few years ago. I've got 325w of light aimed at my work area. All LEDs so it works out to only 40w or so of actual power consumed, and it doesn't get hot. If those were incandecent or halogen lights I'd have a combination model bench / tanning salon.
LED lights have gotten much better and much less expensive in recent years. I've gone from a they can have my incandescents when they pry them from my cold dead fingers type to a hardcore LED fan. I don't think I even have any incandescents left in the house. I also haven't had to change a lightbulb in several years, I hope I don't forget how when an LED burns out someday.
Also on reading glasses I found some awesome glasses last year, they split at the nose and are held together with a magnet. They are so much more handy than traditional glasses and I don't lose them all the time like I did regular reading glasses. No finacial interest, just a big fan.
