However, crucially, you will wish to affirm that you simply’re shopping for authorised eclipse glasses from sincere sellers. Happily, the American Astronomical Society (AAS), has vigilantly vetted merchandise and sellers, so you may make an knowledgeable buying choice.
“Get them now β they may turn into scarce,” Richard Fienberg, an astronomer and senior advisor on the American Astronomical Society, advised Mashable.
“However do not simply randomly get them organized on-line,” Fienberg emphasised. “Verify the AAS listing.”
Over the past complete photo voltaic eclipse to move over the U.S. in 2017, on-line marketplaces like Amazon had been inundated with eclipse glasses. It wasn’t clear how some merchandise had been examined. And it was exhausting to know the place some glasses had been made.
“No person knew if their stuff was protected or not,” Fienberg recalled.
“Get them now β they may turn into scarce.”
It is crucial that any photo voltaic eclipse glasses meet a global security customary for viewing the solar, referred to as “ISO 12312-2.” But simply because somebody prints that it is compliant does not imply that it really is.
“We used to say that you need to search for proof that they adjust to the ISO 12312-2 worldwide security customary for filters for direct viewing of the Solar,” the AAS defined on-line. “However within the weeks earlier than the August 21, 2017, ‘Nice American’ complete photo voltaic eclipse, {the marketplace} was flooded by counterfeit eclipse glasses that had been labeled as ISO-compliant when in actual fact they’d not been correctly examined and proven to be protected.”

Or, a vendor would possibly declare their product is “NASA Permitted” β however NASA would not promote or approve industrial merchandise.
“We’re not going to hyperlink to anyone who’s making false claims,” Fienberg emphasised. “Not solely are we satisfied the merchandise are protected, we really feel snug linking to those firms as a result of they’re following good enterprise practices.”
Fienberg, who up to now has witnessed 14 gorgeous complete photo voltaic eclipses (soon-to-be 15), does numerous this vetting himself. He ensures {that a} vendor is certainly promoting merchandise they obtained from an authorised producer. “I do not take anyone firm’s phrase for it,” he defined. “I additionally contact the producer.”
The AAS listing largely recommends North American firms. That is as a result of the 2024 complete photo voltaic eclipse is crossing a large swath of North America (Mexico, the U.S. and Canada), and the astronomy group would not need the listing to develop too lengthy and overwhelming. Offering β and likewise vetting β 100 decisions just isn’t going to supply a lot profit to somebody who merely needs to see who some legit sellers are.
For instance, this previous week, I used the AAS eclipse glasses provider listing to vet a vendor on Amazon. I situated the identify in 10 seconds, double-checked my buy, and got here away with 10 vetted eclipse glasses to share with my space-intrigued household and associates.
