I just got them today LOL, basically just bought them as a super cheap emergency backup should anything ever happen to my proper prescription glasses.
Although far from perfect, I'd say that my vision is about 3 times better while wearing them compared to my natural vision, but then again I'm extremely nearsighted, like 20/500 level nearsighted.
And yes I'm wearing them right now as I type my messages on my tablet. I'm gonna keep them on and try them out through the day, save for any driving, that's a no-go, while I keep my prescription glasses on my hat to swap out if I need.
