NVU Too clever. You'll need one for every screen, a cleaning regime, and you'll still need a bifocal lens type to read anything else like paper notes or make a snack etc., and no good to show the screen to anyone else who isn't afflicted as they'd have to take it off to see properly. As you say, need to see in practice.
I'm so longsighted I haven't been able to focus even on the horizon for 30 years, but it's a lot of guff to replace simple updated script lenses which I still need to walk away from the screen.
