No (prism) correction for astigmatism, that’s a shame.

Prism isn’t correction for astigmatism. You can see the ‘Axis’ option at the Zeiss web page which is the astimatism correction…

Aha, thanks @cjcoops ;

No (prism) correction for astigmatism, that’s a shame.

The regular people are the ones who do sane risk assessment regarding RF and Apple Vision Pro. Again, there's more delivered RF from electrical wires in walls, desk fans, and portable heaters than there is in Apple Vision Pro.

I’ve agreed with all of what you’ve said to debunk the tin hat brigade, but am surprised about your above throwaway Mike. Digital electronic systems generate lots of EMC issues that a portable heater wouldn’t. 

It's a generalization about risk management from RF as a whole, don't read too much into it. 

There are obviously differences in frequencies and whatnot, but the wide-spectrum spill from portable heaters made by manufacturers with too many adjacent consonants is pretty rough.

I enjoy the high standards of editorial and comment here, and agree it's best to use facts to debunk pseudo-science. I had a quick DuckDuckGo about RF emissions from heaters but didn't turn up much. I understand you were making a generalised point about the ubiquity of harmless RF clutter, but am curious if I'm missing something here Mike. Link maybe?

Experience. It's easy to use a wide-spectrum meter to see the bleed, and it's literally part of meter use training to show that there are sources everywhere, even where you don't expect them. It's also an illustration of exactly how low exposure 0.1 w/kg from Apple Vision Pro really is.

I'll see if I can find data.

I have taken consumer electronic devices through European CE certification anechoic chamber testing and made changes to multilayer circuit board designs to minimise emissions in order to meet required wide band standards.

So I have some experience, interest and curiosity in this topic. 😉

So, from the screenshot, why is the location of the iPhone hidden for one hour during the lockout phase?

Surely that’s exactly when you want to know where it is to track who has stolen it?
