Need some quick info on filmless WP

Just picked up some binos. Went the WP route.

20UA L3 RNVGs.

Can someone explain how these compare to ‘run of the mill’ (lol because all this stuff is expensive and badass) setups?

I’ve done my best to watch videos and read on how night vision works and what’s what, but all the jargon and the meat/potatoes if you will is still confusing me.

Thank you!
