Like blinkers on a racehorse, perhaps?
Kind of, yes, but in a vertical sense rather than a horizontal one.
There is also a smaller and more comfortable device than the classic visor, which is like a pair of safety glasses with most of the lens frosted. A small piece at the bottom (like the close-work part on bifocals) is left clear to see the instruments.
My dad's plane also used to have some fittings on top of the dashboard which held metal slats upright in front of the windscreen. They were angled so that the pilot in the left-hand seat couldn't see between them, but the instructor / safety pilot in the right-hand seat could. Don't know how well the system worked as the slats had long since gone missing.
