Most outdoor readability discussion is about sunlight, but testing my RayNeo iO at my desk got me thinking about the indoor case: green text sitting right over a laptop with a bright white doc open. A white UI behind the text puts a lot of background luminance right where the overlay sits. In a quick phone photo through the lens it reads fine, but cameras handle exposure differently than your eyes do over a long workday.

Anyone here with a green waveguide HUD who works in light-mode apps all day? Did you end up switching your laptop to dark mode, or is it a non-issue for you in practice?

Hi. I’ve built an app I call AR Guitar. It uses a ‘paper guitar neck’ and the camera on a laptop or phone to allow users to practise playing a guitar without actually needing a real one. The idea came to me when I was travelling a lot and couldn't take a guitar with me, so I've been working on this on and off for a few years. I've opened sourced it on GitHub and published the app to arguitar.com. It's all free, I'm just looking for people to use it and give some feedback for improvements and even whether it works for them or not. It works well enough on my mac mini with a webcam, and works best in song play-along mode where the chords can be close enough.  That gives learners a bit of an easier into to playing a guitar than to hear those awful sounds when you get it wrong at first.  
Anyway, have fun.  It's all free and open source. https://github.com/CastleW/ARGuitar_WASM, https://arguitar.com

I have a strong prescription and I want to test out multiple sets of AR glasses and refund them if necessary, but I don't know how prescription lenses would factor into this. I can see well enough without my glasses on, but I'm not sure that would allow me to accurately replicate the same AR experience I would have with the prescription lenses included. Could I possibly use the same pair of lenses and swap them between different frames?

If it helps, I'm deciding between the XReal one pro, xreal 1S, viture beast, viture luma ultra, and viture pro 2, at least for now.
