If by progressive lenses you mean varifocals, they didn't work for me. Trifocals do work well though, especially at night when one has to alternate vision perspective between a dimly lit overhead panel and a screen in front of one's nose.
One of the problems inherent in a two crew cockpit is that panel lighting has to suit both parties. As the older and blinder crew member, I always deferred to the interior illumination requirements of the gumball in the right.
Trifocals are an expensive option and my spare glasses, within handy reach of course, were never quite as superior as my premier pair. Incidentally, stupid as it might look, a spectacle suspender is a good idea when trailing a few hundred £s of kit around one's glazed eyeballs.
