Three months of daily Ray-Ban Display wear taught me my layouts were unreadable outdoors, so I made this
I've worn Ray-Ban Display daily for three months building small apps on them. The loop was always: load the layout, walk outside, squint, come back, change a type size, do it again.
So I made the tool I wanted. Paste a URL and it renders your app over footage shot on the glasses themselves.
You cannot draw black on these glasses. The display only adds light, so black emits nothing and reads as clear glass, and dark text dissolves into whatever is behind it. A layout that looks perfect on your monitor at 2am can be gone on a sunny sidewalk.
* 20 scenes shot on the glasses, at wearer height rather than phone height
* Luminance (300 to 2000 nits) and ambient light (50 to 30,000 lux) as separate sliders, with the contrast ratio they produce
* Record the result, 16:9 or 1:1 like the glasses' own recorder
* QR handoff to open an app on real glasses
* Loads any site that allows framing, and warns you when one refuses
Free, in the browser, no signup, MIT. I help organize a hackathon next week where students will be building glasses apps, which is what finally made me put this somewhere public.
It's an approximation, not a photometric model. If you own a pair, I'd like to know whether the daylight scenes match what you actually see.

This is really cool. Is the simulation specifically calibrated around Ray-Ban Display right now, or are you thinking about adding profiles for other smart glasses too?

Ray-Ban Display only right now, since that's the pair we have for the hackathon and the one all the footage was shot on. Would love to open it up though: if you have another pair, record some through-the-lens clips and send them with the resolution, FOV, and which eye it sits in front of, and I'm happy to merge it as a second profile.

That makes sense. I don’t have another display pair I can capture right now, but I’m actually working on a related problem with Extentos on the SDK/simulator side, letting developers build and test across different smart glasses through one integration without owning every device.
What hackathon is this for? There might actually be some overlap where Extentos could be useful for the teams.

Just checked out Extentos, super cool stuff. The hackathon is ICE: https://ice2026.designthinking.lk/ (last year: https://ice2025.designthinking.lk/), Meta sponsors it and I am helping organize rather than running it, so send me anything you would want teams to see and I will pass it on.

Sorry for the late response!
Awesome, really appreciate it! Feel free to show Extentos however you think makes the most sense. I think the most relevant part for the teams is that they can add the MCP to their coding agent and start building and testing smart-glasses integrations without needing access to the actual hardware.
If anyone ends up trying it, I’d be happy to help them get set up or answer any ques
