There are several good eye exercises that are easy and very effective. Do a search on them. The trick is to do them daily.
I’m probably one of the oldest FReepers here, and altho I have reading glasses, I have no problem reading or typing here. Same with driving or watching TV glasses. Have them, but don’t need or use them.
Similar category and experience as you.
My grandmother taught me (and my sisters) the same eye exercise back in the late ‘40s
Haven’t done them daily but several time a week when I remember to - much more now than earlier in life.
