PSA: You already know (or should know) not to look directly at an eclipse without protective lenses. Any lenses or viewers should meet ISO 12312-2 standards. With an annular eclipse coming up in October 2023, and a total eclipse in April 2024, there are going to be counterfeit eclipse glasses showing up on Amazon, eBay, etc. that will say they're ISO certified but there's no realistic way to verify the claim.

The American Astronomical Society has put together a list of reputable manufacturers of eclipse glasses that meet the ISO standards. Check there before buying.

Don't get blinded by the light!
