when I got glasses it took a year to get used to them. Walking or generally just standing up the ground seemed like twice as far away. I even tripped over curbs a couple times at first. I think i'm still not 100% used to them and it's been like 4-5 years. I tried progressive lenses once and that was 100 times worse. Great for reading, driving, especially reading my phone, and pretty much everything except walking. Had to return them. I got computer glasses. They work pretty good-when I use them.
I use .75 and 1.0 full diopter safety glasses for uspsa and 3 gun. I was having terrible trouble with bifocals and topfocals getting them to work well in different situations.
