Here's how I took care of it. Was given Bi-focals that worked ok. On a day flight adjusted them so the break was right on the glareshield. Above glare shield was the distance lens. Below was the near. Went right to the office after landing and stated this is where the line needs to be. It is different from where they put the line for non-pilots. Also don't go full power on the bottom, that way you can read the instruments cross cockpit.
