You get a protective eye patch you wear before the blast.
A few guys discussed simply moving the patch over the other eye on the way home.
Some of the helmets had gold mirror and some canopies were gold.

They found the easily scratched gold goggles to be a better idea as you could lift you normal visor and put the much cheaper goggles on for a nuke specific mission.

Now they use gold canopies to reflect radar because the round surface of the canopy gives a smaller radar signature than if the radar gets into the cockpit and bounces around before exiting.
