    Now that I’ve read my own comment, I see that it came off harsher then I intended it to. Interpret it literally and not like a sarcastic statement.

    Btw, just occurred to me that these would probably not work in a car at all, because regular glass is usually opaque to IR.

      because regular glass is usually opaque to IR.

      I’m almost 100% positive that this is not correct, because I’ve been driven around by someone wearing PVS-14 NODs with no headlights, on dirt roads, in a commercial van. (Edit - most red dot sights also work very well with NODs, and those have one or two layers of glass, depending on which type of system it is. The sights that don’t work well usually can’t dim the dot enough to avoid massive bloom.) Glass is mostly opaque to thermal though, and a lot of glass significantly reduces UV.
