"Expert Advice on Eclipse Glasses and Cloudy Forecasts"

The American Astronomical Society warns against buying eclipse glasses from online marketplaces like Amazon, eBay, and Temu, as counterfeit and fake products have entered the market. They have compiled a list of over a hundred vetted producers, distributors, and retailers offering lab-tested glasses, including major retailers like Walmart and 7-Eleven. The AAS advises consumers to ensure the seller is identified on the site and listed on their page before purchasing solar viewers online. eBay responded that it only allows the sale of eclipse glasses verified by the AAS, using AI technology and buyer protection programs to ensure authenticity. If you've already purchased glasses from non-listed retailers, there are methods available to test their safety.
