Amazon is issuing refunds to any customers who bought fake eclipse glasses through the site.
It is essential for people who are going to view the eclipse to understand that as long as the Sun is even partially visible, even by a sliver, it can cause significant eye damage if viewed without proper protection. Make sure your eclipse glasses or filters are safe! And remember, only during the short 2 minute or so totality that will occur in the narrow strip across the country will it be safe to look at the Sun without protection. Even so, you must do so with great caution so that you don’t mistakenly view the Sun unprotected when it is partially exposed.
