I'm still blessed with 20-20 vision in one eye and 20-18 in the other. But it isn't as good as it was when I was much younger, so it helps to have some magnification at times.
I have an Optivisor and various hand held magnifying glasses. I also have a couple of those magnifying bench lights with articulating arms which are very helpful. And I always have a small folding magnifying glass in my pocket. It is nearly as useful as carrying a pocket knife. When I pull it out to examine some fine detail at a poorly lighted gunshow or whatever, people who try it always say, "I need to get one of those."
I also have a +1.50 diopter welding magnifying lens in one auto-darkening hood, which can be helpful when doing fine TIG work.
Oh, and don't forget the macro setting on your cell phone camera to enlarge and see fine detail in dark or tight places. I recently used that to read the very faded VIN Number tag on my car trailer.
