night vision question

I havnt done any AP or even viewing in a while. I have a C8 on an avx mount. I love it but recently i went down a rabbit hole and lets just say i want some more options using NV other than my goggles.

Is it possible to just get a NV eyepiece, do they even exist or do i need a setup like i do with viewing the sun?

Like I said its been a while and Im not sure how much has changed and advanced the last few years.

Thanks. Happy Hunting!
