I wear contact lenses, and my eye gal prescribed a set for flying that backs off on the distance vision (I was over 20/10), allowing my aging eyeballs to read the smallest bits on the panel before me without bifocals or blended lenses.
A compatriot of mine did LASIK to 20/40 (or 50 I can't recall) and has a light prescription for distance vision, and a set of bifocals for flying when needed, although he claims with the LASIK, his no correction vision gets the job done most of the time.
