I did some research on this back in 2016 - I wanna just look right at the sun without needing the excuse of an eclipse to do it. It turns out, an awful lot of manufacturers are taking a while to catch up with ISO 12312-2 since it's relatively recent, and a lot of them say the previous standard which I forget the name of is okay by itself.
Boo to them. If I hadn't done my own research and found out which standard was required, it would have been perfectly easy to look at a legit seeming website selling eclipse goggles, see all the numbers, and assume that must surely be the legal standard. These businesses don't realise with this it's not entirely about profit. It's about retinal scarring.
