How to build ultra-slim, discreet AR glasses – is it even possible yet?

Hey everyone,

I’ve been researching augmented reality (AR) glasses, and while the tech has come a long way, most available models still look bulky, obvious, or too “techy” for everyday use.

I’m curious — is anyone here exploring DIY or custom AR glasses that are:

  • Slim and minimal (close to regular eyewear)

  • As undetectable/discreet as possible in public

  • Still functional enough for basic overlays like notifications, navigation, object recognition, etc.

What are the current limitations? Is it the optics, battery, processor, or all of the above that makes them thick? Are there any modular approaches (e.g., integrating components into the arms or using external processing via phone)?

Also, if you’ve tried making a prototype or modifying existing smart glasses — would love to hear your experience. Any component suggestions (like waveguides, micro-displays, or compact sensors) that could help in building a stealthy AR setup?

Looking to brainstorm ideas with fellow tinkerers and hardware enthusiasts.

You should also join the dedicated AR sub on reddit, they will certainly be able to help.

Have you seen google’s latest I/O showcase where they demoed AR glasses? It seems very similar to what you described.

There is also a startup called Brilliant Labs that is making open source glasses:

Check Xreal or similar brands? From the videos they don’t seem that thick.
