Recently tried on some (i think) fancy photochromic type things and the difference was fairly amazing. Wasn't any magnification just clearer. Heard how much they cost and nup, I'll live in my little blurry world for now.
I had photochromic lenses for a while. They change very slowly when it's cold, nearly blinding you when you walk back inside on a cold day, and they do not get dark enough to be good at being sunglasses. Leaves you wondering what the point is.
