The other thing you can try, as it is a very low cost alternative, and you can test the "Toy Attribute" of a digital headset...with surprisingly good performance...
If you have a relatively new smartphone (iPhone 12 or better, Google 5 or better, Samsung 20 or better) with the fancy aperture, ultra low lux low light camera, look for a product called Google Cardboard. Google CB was Google's giggle at their own flop of Google glass, and a laughably toy'ish stab and VR headset moguls like Oculus. Google CB is nothing more than a card board head set, with stereoscopic lenses, that you stick a smartphone into, and you have a VR headset....for about $10. Download the app to set the screen up for 3d viewing. For $10, with an existing smartphone, you have color/3D NV goggles...with recording, zoom, videogames, and SKSboards.com...in
3-flipping-D.

Just add an IR only flashlight from AliBaba...$20...and you have fun toy that will out perform most, if not all sub$500 digital NV on the market.
For less than $40 investment, with the purchase of batteries, you got a cool gadget to play with and you can test the budget side of Digital NV tech.
