Look up the Rokid smart glasses. They’re pretty close to what you’re describing. Camera, AI assistant, live translations in over 80 different languages, auto transcribe, monochrome heads up display, and they look like normal glasses. They’re surprisingly lightweight for the amount of technology that’s in them.

A little pre warning though, they start at $599. There is also the Even Realities G1 smart glasses which are a little cheaper and do most of the same stuff, but there is no camera on them.
