I have a very temporary solution to the fact that as I'm ageing my optical prescription is changing. My distance glasses are just a bit too strong but also don't correct for my near-sightedness. I'm getting some new ones. Turns out that while waiting for new lenses to be made up a pair of lightweight +1.5 reading glasses on top of the old ones works just fine and is comfortable to boot!
I wouldn't try to use any machinery other than a desktop computer while wearing them and it's not an all day thing but I can see the screen well from a couple of feet away and it's worth it just to see my wife do a double-take when she walks in.
