I would expect them to look like the FJ goggles. Reusing the design is very UC as of late. Idk if they'd refer to them as night-vision goggles, simply because the technology wasn't around then. They were very WWII. Probably just protection goggles or something period-related as earlier stated.
The matte backdrop, after fog, will probably not bother me as much as it does now. It's meant to disguise the building and provide dimension to the structure, so in that sense it's fine, but I still would have preferred a relief-like set. Around the Little Mermaid building, there's rockwork extended over a service road in order to completely shield view of it from Storybook Circus. But if it means having a ride of lesser quality, I'll take the simple backdrop.
