Gizmodo:

Congratulations to those of you who used proper solar eclipse glasses and witnessed the phenomenon without permanently damaging your vision. Good job! But now you’re probably wondering what to do with those flimsy pieces of cardboard and black polymer that were basically priceless just hours ago.

Fortunately, Astronomers Without Borders has offered to take them off your hands so that children will be able to use them in future eclipses. The organization says it will soon announce a program dedicated to redistributing glasses to schools in Asia and South America, where there will be solar eclipses in 2019.

What a great idea and wonderful service by Astronomers Without Borders.
