Mine either. But in this instance I don't think it would make much
difference.
When we're young our eyes can snap from infinity to close-up vision -and
back- in just a blink, but that would be several thousand miles per hour if
we were converting it to closing speed.
At any sort of reasonable closing speed your eyes should be able to change
focus that quickly with no problem.

Good luck! Eye surgery is getting pretty amazing these days!
