The total solar eclipse of the Sun is happening on Aug. 21—and you can’t use your regular ol’ sunnies to view the spectacle.
NASA has issued strong warnings about using special-purpose solar filters, a.k.a. “eclipse glasses,” to view the event. Websites, including Amazon, are selling counterfeit solar glasses that could be potentially life-threatening to your retinae. Some Amazon glasses have since been recalled.
How to tell if you’re buying the real deal
NASA has released a list of pre-approved solar glasses that have been certified to international safety standards. NASA is also giving away free eclipse glasses at certain locations, which can be tracked on this interactive map. Check dates and times to make sure you don’t miss the giveaways.
Below is a list of places, provided by NASA, where you can get ahold of the solar sunnies.
