This exactly. They claim certifications and safety ratings they do not have. If they're not actually suitable, the result can be severe eye damage. As for identifying the "real thing", I found the specific brand NASA recommends, and then tried to find a reputable supplier through Amazon with reviews indicating, by people who've tested them, that they were genuine. It's still not foolproof, but at least it's something. At minimum, if you're in the market for glasses for the eclipse, if you can see anything other than the sun when you put them on, they're not dark enough. Solar glasses are REALLY dark.
