What should you do with your used eclipse glasses?

Millions of people ogled the skies using eclipse viewers, avidly watching as the moon blotted out the sun. But now that all this celestial majesty has passed, what should you do with your eclipse glasses?

Though it's tempting to save them until the next solar eclipse in 2024, (which will cross eastern Canada, the central U.S. and part of Mexico) you must first check with the company to see if the glasses will last. As Cassy Sommer at Staten Island Live reports, some eclipse glasses manufacturers warn that the lenses expire after three years. But according to NASA, if the glasses are compliant with the ISO 12312-2 safety standards, which were adopted in 2015, they should be reusable indefinitely. Just make sure you keep them in a safe spot: Seven years in a junk drawer will likely lead to scratches or abrasions, which can make the glasses dangerous to wear.

Perhaps the most useful thing you can do with your glasses is to donate them to Astronomers Without Borders. The organization will soon announce a program to collect the used glasses and distribute them to schools in South America and parts of Asia, which will experience their own solar eclipses in 2019.

While the organization will not collect the glasses themselves, they are partnering with corporate sponsors who will set up drop-off sites for the used eyewear. 

The organization hosted a similar program in 2013, collecting donations to send eclipse glasses to west and central Africa for a total eclipse that passed over the continent in November of that year. In total, they supplied 13,700 glasses to schools in eight countries. 

But even more important than getting kids to look up at the stellar event, the AWB hopes the eclipse enthusiasm will help inspire more students to pursue fields in science, technology and mathematics. “Once they look up, we don't want them to stop,” AWB education director Lindsay Bartolone tells Mike Simmons at Sky and Telescope.

That goes for the United States as well. In the wake of today's eclipse, AWB is sending professional and amateur astronomers into the community to help teachers conduct sun-based lessons and experiments, reports Simmons.

Local schools may also be interested in your used eclipse glasses for astronomy activities or experiments, reports Patti Roth of Earth911. You should ask local schools if they have any interest before you toss or recycle the glasses, Irene Pease, board member of the Amateur Astronomers Association of New York, tells Roth. 

If donating doesn't tickle your fancy, it’s fine to pull the solar-filter lenses out of the glasses and recycle the paper or cardboard frames, reports Josh Magness for the Miami Herald. Specialty recyclers like camera stores might even accept the solar filters for recycling. Glasses with plastic frames are likely not recyclable.

And if none of those options pan out, Pease suggests that you can use the lenses as parts of arts and crafts projects. “I wouldn’t mind a pair of eclipse-filter earrings,” she tells Roth, “as an astro-fashion statement.”

Finally, keeping the glasses as a souvenir is always an option. As Brooks Mitchell, education coordinator for the nonprofit Space Science Institute in Boulder, Colo, tells Roth. Mitchell is planning to keep the glasses to remind himself “of the awesome celestial experience.”

    I will donate the eclipse glasses that I received. The text states, "Perhaps the most useful thing you can do with your glasses is to donate them to Astronomers Without Borders. The organization will soon announce a program to collect the used glasses and distribute them to schools in South America and parts of Asia, which will experience their own solar eclipses in 2019" (Daley). By doing this I will help people who might not be able to afford the glasses to be able to look at the eclipse.

    I agree with what "what should you do with your use eclipse glasses" because its smart to recycle the lenses so there can be made more solar cameras but that's mostly if you live where the solar eclipse is but if you went there to travel you should keep them as a souvenir because you probably wont get anymore of them but you shouldn't trash them like the article says 'you should recycle them' but never throw them away because there are a lot of uses for them.

    It would not be a good idea to keep your used eclipse glasses.The text states that "Seven years in a junk drawer will likely lead to scratches or abrasions, which can make the glasses dangerous to wear." Keeping your glasses is not the smartest idea,but if you are willing to take a chance in keeping them make sure they are in a safe spot. It would most likely not be a good idea to keep your used eclipse glasses.

    I agree with not "throwing away" the eclipse glasses. Like the article said, recycling them would be smarter to do because their are many different uses for the glasses. Sending the glasses to foreign students for when an eclipse happens where they stay would be awesome and should always be continued.
