Hm. They look very interesting. Wonder if there's anywhere I could try them out. I wear glasses for mild astigmatism, and I've always wondered if that's a blocker. For things like https://brilliant.xyz/ that's obviously less of an issue, but also they aren't aiming at the same sort of display.

Oh now that's even more interesting. Apparently they include a normal frame behind the display, so you can have your optician fit prescription lenses.

They're in a reasonable price range, too. Looking better and better. Thanks for the suggestion!
