first pair of glasses! should i get my eyes checked again?

hey y’all, i got my first glasses prescription in september of last year (2023) and only recently had the money and drive to order myself a pair. i got them today and at first it was amazing because everything was clear again, but after wearing them for some time, it seems like my eyes are struggling to focus? i can’t tell if its because im not used to just being able to see without actively focusing, or if my prescription is a bit off.
