On Monday, August 21, America hosted what may have been the most-viewed solar eclipse in history. While those of us in the United States are still processing the awesome sight, residents of South America and Asia are just starting to look forward to the next total eclipse in 2019—and anyone who still has their protective glasses on hand can help them prepare.

According to Gizmodo, Astronomers Without Borders is accepting donations of used eyewear following Monday’s event. Any glasses they collect will be redistributed to schools across Asia and South America where children can use them to view the world’s next total eclipse in safety.

Astronomers Without Borders is dedicated to making astronomy accessible to people around the world. For this most recent eclipse, they provided 100,000 free glasses to schools, youth community centers, and children's hospitals in the U.S. If you’re willing to contribute to their next effort, hold on to your specs for now—the group plans to the announce the address where you can send them in the near future. Donors who don't have the patience to wait for updates on the group's Facebook page can send glasses immediately to its corporate sponsor, Explore Scientific, at 1010 S. 48th Street, Springdale, Arizona 72762.

Not sure if your glasses are suitable for reuse? Here’s the criteria they should meet for sun-gazing.
