It’s harder than it was before I needed bifocals, but yeah.

Once you learn the trick of it, it gets easier to do.

I wanna say I was late teens/early twenties when they first started showing up in my area, and I stood in the store I first saw one for like a half hour trying to see the image. My vision was kinda bad across the board, even then. But I got the first one, which was a boat, and then flipped through the rest of the selection they had, maybe five or six different ones?

But any time I got new glasses, it would take a few minutes to adjust when I’d run across one again. Same if I needed new ones.

They really are fun
