Wearing progressive lenses for the first time. It's gonna take quite some getting used to. Looking right down the middle, vision is sharp and clear as a bell. Being able to read text just by shifting the gaze down slightly is certainly more convenient than having to adjust my normal lenses for the correct focal length, or removing them altogether so I can read whatever is pressing up against my face.
However, to compensate for some amazingly high myopia, even with expensively high index glass, the lenses are super thick, making peripheral vision totally crap. With these babies on, I can categorically confirm that the world is curved around the edges. And if I happen to turn up my nose at you, it's not like I don't respect you. I'm just trying to read what's printed on your t-shirt.
