Someone told me a while ago that if you have a "must wear corrective

carry a pair of regular glasses while flying. Is that true? And if so,
does anyone have a reference?

Untrue. Might not be a bad idea.

If HOWEVER, you need close distance correction, you will also have an
endorsement that says "must possess corrective lenses..." You can't
use monovision contacts either.
