I have tried said devices such things of dark magic exist and yet they are not good enough unless you have two pairs which is a pain and gives me vertigo.
Top tip: Don't wear both pairs at the same time
My natural eyesight is rather poor and now age has gifted me with presbyopia to go with the myopia and astigmatism. I need 3 pairs of glasses. One for reading, one for slightly longer range (e.g. monitor distance) and one for longer than that. It's unsettling to switch between them but it has to be done. I close my eyes during the swap and look immediately at something that's the right distance for the pair I've put on. Works well enough for me.
I cunningly bought the same frames for each pair, so I don't know which is which until I put them on. That was an...interesting...choice.
You could try varifocals, but they might or might not suit you. Some people find them excellent, some people don't. Something relevant that I didn't know before - if you have more than mild astigmatism then you might well find that glasses with a high refractive index leave you with very poor peripheral vision. If so, that makes varifocals pretty much useless you go for a lower refractive index (which will be thicker).
You could also try a combo of contact lenses all the time and glasses on top for when you're looking at something closer. The contact lenses for your normal prescription and the glasses specifically for the
difference between your normal prescription and your close range prescription. Don't try it with your close range prescription. That won't work at all well.
On a related note, I found that a Kindle Paperwhite (and probably other ebook hardware) was just the job for reading as my eyesight got worse with age. Being backlit makes it
much more comfortable for me to read than print on paper. Low light vision tends to deteriotate with age as well.
