The country’s top astronomical organization says it’s alarmed by reports that potentially unsafe eclipse glasses are flooding the market in advance of the all-American solar eclipse on Aug. 21 – and in response, it has issued a list of approved manufacturers and vendors.

“This would not be sufficient to protect your eyes from the sun,” the reviewer wrote in his one-star assessment. “I would never trust my eyesight to a pair of glasses from China.”
