At 75 I can drive legally without glasses, but need corrective lenses for up-close work. I get regular eye exams and the doc gives me a real prescription, but it is a simple one with little correction for astigmatism and no other problems. So, with her knowledge, I just buy inexpensive reading glasses. I get them in an assortment of powers, some close to my prescription and others with greater powers for real close work. They are inexpensive, many cost $5 or less and I probably have a dozen pairs. I consider them expendable and just leave them in all the places where I use them. I have several pairs on my main workbench. These various glasses serve for about 90% of my needs.
In addition I have two name brand visors and a couple more cheap imports. They are also left where I need and use them.
When all of the above fails, I have four magnifying lenses in my pocket at all times. They have powers of 2X, 10X, 15X, and 20X. If all of that fails, I have two microscopes. Three if you count the USB one.
I can usually see what I want to see.
I have used the magnifying lamps and they are OK. But I find having a variety of magnification devices available a lot better.
