Donations are an option, too. Astronomers Without Borders is looking to collect the glasses that were passed out and sold for Monday's eclipse and redistribute them in South American and Asian schools in 2019 when another solar eclipse will happen in about two years.
A similar program occurred in 2013 to send glasses to west and central Africa. Organizers collected 13,700 glasses that were distributed to schools in eight countries, Smithsonian Magazine reported.
Other groups say check with schools or rec programs to see if they can use the glasses for astronomy activities, Time reported.
A final option is to recycle them. Take out the lenses and recycle the cardboard frames. As for the lenses, contact a local camera shop to see if they will take them to recycle with camera film, USA Today reported.
