When meta glasses work to read something, they work very very well. But, when they fail, they fail spectacularly. For some reason, I could not get them to read me something that was right in front of me, the same exact thing I'd done before with other documents I had sitting before me. And other appps did much better.
It's a reminder that this device hasn't been enhanced for blind people's specific needs. It's a device/platform that happens to have features that help.
