About 15 years ago my wife got Crystalens lens replacements for cataracts. These lenses are self focusing. Hers were pretty good for several years, but gradually scar tissue grew over the adjustable mechanism, so now she needs glasses. But at least the cataracts are gone. Her eye doctor gave a presentation at a ophthalmologist conference many years ago slamming the product. That was because many of them did not work at all even from the beginning.

So your brand is working for you, as did my wife's at first. Years down the road, perhaps you will need glasses.

There are several eyeglass lenses that would be more applicable to what we do, but are dedicated to shop work. They would have mid-range (arms length to a few feet) in the top with close reading in the bottom. Before getting a permanent change through surgery, I'd recommend having it simulated with contact lenses. During my +30 years as an eyecare professional, I've seen many cases of regret. While numbers are involved in vision correction, in the end, it's how the brain interprets the pictures it receives from the eyes and the ability to fuse the images into a three dimensional picture. What works for one person may not work for others.

Dave, when you say "single vision mid range glasses" are you talking about dime store reading glasses, or is this something special? Source? Sounds like what I need.
