Amazon shared the following statement with Channel 3 Monday afternoon:
"Out of an abundance of caution and in the interests of our customers, we asked third-party sellers that were offering solar eclipse glasses to provide documentation to verify their products were compliant with relevant safety standards. The offers from sellers who provided this safety documentation remain available to customers. The listings from sellers who did not provide the appropriate documentation have been removed and customers who purchased from them were notified last week. Customers can contact Amazon customer service with any questions or concerns."
