“This is an opportunity for schools to have a first-hand science experience that they might not otherwise have,” Simmons told Gizmodo of the upcoming donation program. “Many schools in developing countries don’t have resources for science education and this is a rare opportunity that inspires students and teachers and shows them that science is something they can do. It can be a ray of hope for young people who don’t otherwise see a path to a career like this.”
There’s also the option to remove the solar-filter lenses from your glasses and recycle the paper frames. (Plastic frames are reportedly unlikely to be acceptable for recycling.) According to the Miami Herald, camera stores which process film may be able to recycle the filters. If not, CNET suggests using them to make your own camera filters for cool photos.
If you don’t end up donating or recycling the glasses, there’s also the option to reuse them yourself in 2024, when the next total solar eclipse will be visible in the United States. Just be sure they’re safe to use indefinitely. While some manufacturers warn that the lenses expire in three years, NASA reports that eclipse glasses which are compliant with the ISO 12312-2 safety standard can be reused for as long as you want, as long as the filters aren’t damaged.
