Just an update. . .I can see amazingly well during daylight hours - the lenses are hard to insert, but I am getting the hang of it, & they are (counter-intuitively) very comfortable. But at night my vision is terrible, not one street name, road sign or whatever is legible; I had a bad fright driving a detour home the other night, got completely lost as I couldn't follow the signage. So apparently adding more diopter strength will help so I will have to part with them so the lab can do adjustments.. . . .but I can see all the notes now, even in Bach partituras
I would recommend them, though. . . crystal clear vision & no Picasso-like astigmatic distortions!
